- * cli()/sti() will be obsolete in 2.6.11.
- *
- * Revision 1.7 2005/01/03 13:35:46 starvik
- * Removed obsolete stuff.
- * Mark fast timer IRQ as not shared.
- *
- * Revision 1.6 2004/05/14 10:18:39 starvik
- * Export fast_timer_list
- *
- * Revision 1.5 2004/05/14 07:58:01 starvik
- * Merge of changes from 2.4
- *
- * Revision 1.4 2003/07/04 08:27:41 starvik
- * Merge of Linux 2.5.74
- *
- * Revision 1.3 2002/12/12 08:26:32 starvik
- * Don't use C-comments inside CVS comments
- *
- * Revision 1.2 2002/12/11 15:42:02 starvik
- * Extracted v10 (ETRAX 100LX) specific stuff from arch/cris/kernel/
- *
- * Revision 1.1 2002/11/18 07:58:06 starvik
- * Fast timers (from Linux 2.4)
- *
- * Revision 1.5 2002/10/15 06:21:39 starvik
- * Added call to init_waitqueue_head
- *
- * Revision 1.4 2002/05/28 17:47:59 johana
- * Added del_fast_timer()
- *
- * Revision 1.3 2002/05/28 16:16:07 johana
- * Handle empty fast_timer_list
- *
- * Revision 1.2 2002/05/27 15:38:42 johana
- * Made it compile without warnings on Linux 2.4.
- * (includes, wait_queue, PROC_FS and snprintf)
- *
- * Revision 1.1 2002/05/27 15:32:25 johana
- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
- *
- * Revision 1.8 2001/11/27 13:50:40 pkj
- * Disable interrupts while stopping the timer and while modifying the
- * list of active timers in timer1_handler() as it may be interrupted
- * by other interrupts (e.g., the serial interrupt) which may add fast
- * timers.
- *
- * Revision 1.7 2001/11/22 11:50:32 pkj
- * * Only store information about the last 16 timers.
- * * proc_fasttimer_read() now uses an allocated buffer, since it
- * requires more space than just a page even for only writing the
- * last 16 timers. The buffer is only allocated on request, so
- * unless /proc/fasttimer is read, it is never allocated.
- * * Renamed fast_timer_started to fast_timers_started to match
- * fast_timers_added and fast_timers_expired.
- * * Some clean-up.
- *
- * Revision 1.6 2000/12/13 14:02:08 johana
- * Removed volatile for fast_timer_list
- *
- * Revision 1.5 2000/12/13 13:55:35 johana
- * Added DEBUG_LOG, added som cli() and cleanup
- *
- * Revision 1.4 2000/12/05 13:48:50 johana
- * Added range check when writing proc file, modified timer int handling
- *
- * Revision 1.3 2000/11/23 10:10:20 johana
- * More debug/logging possibilities.
- * Moved GET_JIFFIES_USEC() to timex.h and time.c
- *
- * Revision 1.2 2000/11/01 13:41:04 johana
- * Clean up and bugfixes.
- * Created new do_gettimeofday_fast() that gets a timeval struct
- * with time based on jiffies and *R_TIMER0_DATA, uses a table
- * for fast conversion of timer value to microseconds.
- * (Much faster the standard do_gettimeofday() and we don't really
- * want to use the true time - we want the "uptime" so timers don't screw up
- * when we change the time.
- * TODO: Add efficient support for continuous timers as well.
- *
- * Revision 1.1 2000/10/26 15:49:16 johana
- * Added fasttimer, highresolution timers.

- * Revision 1.48 2003/05/30 11:03:57 johana
- * Implemented rs_send_xchar() by disabling the DMA and writing manually.
- * Added e100_disable_txdma_channel() and e100_enable_txdma_channel().
- * Fixed rs_throttle() and rs_unthrottle() to properly call rs_send_xchar

- * Revision 1.5 2002/11/14 15:59:49 starvik
- * Linux 2.5 port of the latest serial driver from 2.4. The work queue stuff
- * probably doesn't work yet.
- *
- * Revision 1.42 2002/11/05 09:08:47 johana
- * Better implementation of rs_stop() and rs_start() that uses the XOFF
- * register to start/stop transmission.
- * change_speed() also initilises XOFF register correctly so that
- * auto_xoff is enabled when IXON flag is set by user.
- * This gives fast XOFF response times.
- *
- * Revision 1.41 2002/11/04 18:40:57 johana
- * Implemented rs_stop() and rs_start().
- * Simple tests using hwtestserial indicates that this should be enough
- * to make it work.
- *
- * Revision 1.40 2002/10/14 05:33:18 starvik
- * RS-485 uses fast timers even if SERIAL_FAST_TIMER is disabled
- *
- * Revision 1.39 2002/09/30 21:00:57 johana
- * Support for CONFIG_ETRAX_SERx_DTR_RI_DSR_CD_MIXED where the status and
- * control pins can be mixed between PA and PB.
- * If no serial port uses MIXED old solution is used
- * (saves a few bytes and cycles).
- * control_pins struct uses masks instead of bit numbers.
- * Corrected dummy values and polarity in line_info() so
- * /proc/tty/driver/serial is now correct.
- * (the E100_xxx_GET() macros is really active low - perhaps not obvious)
- *
- * Revision 1.38 2002/08/23 11:01:36 starvik
- * Check that serial port is enabled in all interrupt handlers to avoid
- * restarts of DMA channels not assigned to serial ports
- *
- * Revision 1.37 2002/08/13 13:02:37 bjornw
- * Removed some warnings because of unused code
- *
- * Revision 1.36 2002/08/08 12:50:01 starvik
- * Serial interrupt is shared with synchronous serial port driver
- *
- * Revision 1.35 2002/06/03 10:40:49 starvik
- * Increased RS-485 RTS toggle timer to 2 characters
- *
- * Revision 1.34 2002/05/28 18:59:36 johana
- * Whitespace and comment fixing to be more like etrax100ser.c 1.71.
- *
- * Revision 1.33 2002/05/28 17:55:43 johana
- * RS-485 uses FAST_TIMER if enabled, and starts a short (one char time)
- * timer from tranismit_chars (interrupt context).
- * The timer toggles RTS in interrupt context when expired giving minimum
- * latencies.
- *
- * Revision 1.32 2002/05/22 13:58:00 johana
- * Renamed rs_write() to raw_write() and made it inline.
- * New rs_write() handles RS-485 if configured and enabled
- * (moved code from e100_write_rs485()).
- * RS-485 ioctl's uses copy_from_user() instead of verify_area().
- *
- * Revision 1.31 2002/04/22 11:20:03 johana
- * Updated copyright years.
- *
- * Revision 1.30 2002/04/22 09:39:12 johana
- * RS-485 support compiles.
- *
- * Revision 1.29 2002/01/14 16:10:01 pkj
- * Allocate the receive buffers dynamically. The static 4kB buffer was
- * too small for the peaks. This means that we can get rid of the extra
- * buffer and the copying to it. It also means we require less memory
- * under normal operations, but can use more when needed (there is a
- * cap at 64kB for safety reasons). If there is no memory available
- * we panic(), and die a horrible death...
- *
- * Revision 1.28 2001/12/18 15:04:53 johana
- * Cleaned up write_rs485() - now it works correctly without padding extra
- * char.
- * Added sane default initialisation of rs485.
- * Added #ifdef around dummy variables.
- *
- * Revision 1.27 2001/11/29 17:00:41 pkj
- * 2kB seems to be too small a buffer when using 921600 bps,
- * so increase it to 4kB (this was already done for the elinux
- * version of the serial driver).
- *
- * Revision 1.26 2001/11/19 14:20:41 pkj
- * Minor changes to comments and unused code.
- *
- * Revision 1.25 2001/11/12 20:03:43 pkj
- * Fixed compiler warnings.
- *
- * Revision 1.24 2001/11/12 15:10:05 pkj
- * Total redesign of the receiving part of the serial driver.
- * Uses eight chained descriptors to write to a 4kB buffer.
- * This data is then serialised into a 2kB buffer. From there it
- * is copied into the TTY's flip buffers when they become available.
- * A lot of copying, and the sizes of the buffers might need to be
- * tweaked, but all in all it should work better than the previous
- * version, without the need to modify the TTY code in any way.
- * Also note that erroneous bytes are now correctly marked in the
- * flag buffers (instead of always marking the first byte).
- *
- * Revision 1.23 2001/10/30 17:53:26 pkj
- * * Set info->uses_dma to 0 when a port is closed.
- * * Mark the timer1 interrupt as a fast one (SA_INTERRUPT).
- * * Call start_flush_timer() in start_receive() if
- * CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST is defined.
- *
- * Revision 1.22 2001/10/30 17:44:03 pkj
- * Use %lu for received and transmitted counters in line_info().
- *
- * Revision 1.21 2001/10/30 17:40:34 pkj
- * Clean-up. The only change to functionality is that
- * CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS(=5) is used instead of
- * MAX_FLUSH_TIME(=8).
- *
- * Revision 1.20 2001/10/30 15:24:49 johana
- * Added char_time stuff from 2.0 driver.
- *
- * Revision 1.19 2001/10/30 15:23:03 johana
- * Merged with 1.13.2 branch + fixed indentation
- * and changed CONFIG_ETRAX100_XYS to CONFIG_ETRAX_XYZ

- * Revision 1.18 2001/09/24 09:27:22 pkj
- * Completed ext_baud_table[] in cflag_to_baud() and cflag_to_etrax_baud().
- *
- * Revision 1.17 2001/08/24 11:32:49 ronny
- * More fixes for the CONFIG_ETRAX_SERIAL_PORT0 define.
- *
- * Revision 1.16 2001/08/24 07:56:22 ronny
- * Added config ifdefs around ser0 irq requests.
- *
- * Revision 1.15 2001/08/16 09:10:31 bjarne
- * serial.c - corrected the initialization of rs_table, the wrong defines
- * where used.
- * Corrected a test in timed_flush_handler.
- * Changed configured to enabled.
- * serial.h - Changed configured to enabled.
- *
- * Revision 1.14 2001/08/15 07:31:23 bjarne
- * Introduced two new members to the e100_serial struct.
- * configured - Will be set to 1 if the port has been configured in .config
- * uses_dma - Should be set to 1 if the port uses DMA. Currently it is set
- * to 1
- * when a port is opened. This is used to limit the DMA interrupt
- * routines to only manipulate DMA channels actually used by the
- * serial driver.
- *
- * Revision 1.13.2.2 2001/10/17 13:57:13 starvik
- * Receiver was broken by the break fixes
- *
- * Revision 1.13.2.1 2001/07/20 13:57:39 ronny
- * Merge with new stuff from etrax100ser.c. Works but haven't checked stuff
- * like break handling.
- *
- * Revision 1.13 2001/05/09 12:40:31 johana
- * Use DMA_NBR and IRQ_NBR defines from dma.h and irq.h
- *
- * Revision 1.12 2001/04/19 12:23:07 bjornw
- * CONFIG_RS485 -> CONFIG_ETRAX_RS485
- *
- * Revision 1.11 2001/04/05 14:29:48 markusl
- * Updated according to review remarks i.e.
- * -Use correct types in port structure to avoid compiler warnings
- * -Try to use IO_* macros whenever possible
- * -Open should never return -EBUSY
- *
- * Revision 1.10 2001/03/05 13:14:07 bjornw
- * Another spelling fix
- *
- * Revision 1.9 2001/02/23 13:46:38 bjornw
- * Spellling check
- *
- * Revision 1.8 2001/01/23 14:56:35 markusl
- * Made use of ser1 optional
- * Needed by USB
- *
- * Revision 1.7 2001/01/19 16:14:48 perf
- * Added kernel options for serial ports 234.
- * Changed option names from CONFIG_ETRAX100_XYZ to CONFIG_ETRAX_XYZ.
- *
- * Revision 1.6 2000/11/22 16:36:09 bjornw
- * Please marketing by using the correct case when spelling Etrax.
- *
- * Revision 1.5 2000/11/21 16:43:37 bjornw
- * Fixed so it compiles under CONFIG_SVINTO_SIM
- *
- * Revision 1.4 2000/11/15 17:34:12 bjornw
- * Added a timeout timer for flushing input channels. The interrupt-based
- * fast flush system should be easy to merge with this later (works the same
- * way, only with an irq instead of a system timer_list)
- *
- * Revision 1.3 2000/11/13 17:19:57 bjornw
- * * Incredibly, this almost complete rewrite of serial.c worked (at least
- * for output) the first time.
- *
- * Items worth noticing:
- *
- * No Etrax100 port 1 workarounds (does only compile on 2.4 anyway now)
- * RS485 is not ported (why can't it be done in userspace as on x86 ?)
- * Statistics done through async_icount - if any more stats are needed,
- * that's the place to put them or in an arch-dep version of it.
- * timeout_interrupt and the other fast timeout stuff not ported yet
- * There be dragons in this 3k+ line driver
- *
- * Revision 1.2 2000/11/10 16:50:28 bjornw
- * First shot at a 2.4 port, does not compile totally yet
- *
- * Revision 1.1 2000/11/10 16:47:32 bjornw
- * Added verbatim copy of rev 1.49 etrax100ser.c from elinux
- *
- * Revision 1.49 2000/10/30 15:47:14 tobiasa
- * Changed version number.
- *
- * Revision 1.48 2000/10/25 11:02:43 johana
- * Changed %ul to %lu in printf's
- *
- * Revision 1.47 2000/10/18 15:06:53 pkj
- * Compile correctly with CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST and
- * CONFIG_ETRAX_SERIAL_PROC_ENTRY together.
- * Some clean-up of the /proc/serial file.
- *
- * Revision 1.46 2000/10/16 12:59:40 johana
- * Added CONFIG_ETRAX_SERIAL_PROC_ENTRY for statistics and debug info.
- *
- * Revision 1.45 2000/10/13 17:10:59 pkj
- * Do not flush DMAs while flipping TTY buffers.
- *
- * Revision 1.44 2000/10/13 16:34:29 pkj
- * Added a delay in ser_interrupt() for 2.3ms when an error is detected.
- * We do not know why this delay is required yet, but without it the
- * irmaflash program does not work (this was the program that needed
- * the ser_interrupt() to be needed in the first place). This should not
- * affect normal use of the serial ports.
- *
- * Revision 1.43 2000/10/13 16:30:44 pkj
- * New version of the fast flush of serial buffers code. This time
- * it is localized to the serial driver and uses a fast timer to
- * do the work.
- *
- * Revision 1.42 2000/10/13 14:54:26 bennyo
- * Fix for switching RTS when using rs485
- *
- * Revision 1.41 2000/10/12 11:43:44 pkj
- * Cleaned up a number of comments.
- *
- * Revision 1.40 2000/10/10 11:58:39 johana
- * Made RS485 support generic for all ports.
- * Toggle rts in interrupt if no delay wanted.
- * WARNING: No true transmitter empty check??
- * Set d_wait bit when sending data so interrupt is delayed until
- * fifo flushed. (Fix tcdrain() problem)
- *
- * Revision 1.39 2000/10/04 16:08:02 bjornw
- * * Use virt_to_phys etc. for DMA addresses
- * * Removed CONFIG_FLUSH_DMA_FAST hacks
- * * Indentation fix
- *
- * Revision 1.38 2000/10/02 12:27:10 mattias
- * * added variable used when using fast flush on serial dma.
- * (CONFIG_FLUSH_DMA_FAST)
- *
- * Revision 1.37 2000/09/27 09:44:24 pkj
- * Uncomment definition of SERIAL_HANDLE_EARLY_ERRORS.
- *
- * Revision 1.36 2000/09/20 13:12:52 johana
- * Support for CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS:
- * Number of timer ticks between flush of receive fifo (1 tick = 10ms).
- * Try 0-3 for low latency applications. Approx 5 for high load
- * applications (e.g. PPP). Maybe this should be more adaptive some day...
- *
- * Revision 1.35 2000/09/20 10:36:08 johana
- * Typo in get_lsr_info()
- *
- * Revision 1.34 2000/09/20 10:29:59 johana
- * Let rs_chars_in_buffer() check fifo content as well.
- * get_lsr_info() might work now (not tested).
- * Easier to change the port to debug.
- *
- * Revision 1.33 2000/09/13 07:52:11 torbjore
- * Support RS485
- *
- * Revision 1.32 2000/08/31 14:45:37 bjornw
- * After sending a break we need to reset the transmit DMA channel
- *
- * Revision 1.31 2000/06/21 12:13:29 johana
- * Fixed wait for all chars sent when closing port.
- * (Used to always take 1 second!)
- * Added shadows for directions of status/ctrl signals.
- *
- * Revision 1.30 2000/05/29 16:27:55 bjornw
- * Simulator ifdef moved a bit
- *
- * Revision 1.29 2000/05/09 09:40:30 mattias
- * * Added description of dma registers used in timeout_interrupt
- * * Removed old code
- *
- * Revision 1.28 2000/05/08 16:38:58 mattias
- * * Bugfix for flushing fifo in timeout_interrupt
- * Problem occurs when bluetooth stack waits for a small number of bytes
- * containing an event acknowledging free buffers in bluetooth HW
- * As before, data was stuck in fifo until more data came on uart and
- * flushed it up to the stack.
- *
- * Revision 1.27 2000/05/02 09:52:28 jonasd
- * Added fix for peculiar etrax behaviour when eop is forced on an empty
- * fifo. This is used when flashing the IRMA chip. Disabled by default.
- *
- * Revision 1.26 2000/03/29 15:32:02 bjornw
- * 2.0.34 updates
- *
- * Revision 1.25 2000/02/16 16:59:36 bjornw
- * * Receive DMA directly into the flip-buffer, eliminating an intermediary
- * receive buffer and a memcpy. Will avoid some overruns.
- * * Error message on debug port if an overrun or flip buffer overrun occurs.
- * * Just use the first byte in the flag flip buffer for errors.
- * * Check for timeout on the serial ports only each 5/100 s, not 1/100.
- *
- * Revision 1.24 2000/02/09 18:02:28 bjornw
- * * Clear serial errors (overrun, framing, parity) correctly. Before, the
- * receiver would get stuck if an error occurred and we did not restart
- * the input DMA.
- * * Cosmetics (indentation, some code made into inlines)
- * * Some more debug options
- * * Actually shut down the serial port (DMA irq, DMA reset, receiver stop)
- * when the last open is closed. Corresponding fixes in startup().
- * * rs_close() "tx FIFO wait" code moved into right place, bug & -> && fixed
- * and make a special case out of port 1 (R_DMA_CHx_STATUS is broken for that)
- * * e100_disable_rx/enable_rx just disables/enables the receiver, not RTS
- *
- * Revision 1.23 2000/01/24 17:46:19 johana
- * Wait for flush of DMA/FIFO when closing port.
- *
- * Revision 1.22 2000/01/20 18:10:23 johana
- * Added TIOCMGET ioctl to return modem status.
- * Implemented modem status/control that works with the extra signals
- * (DTR, DSR, RI,CD) as well.
- * 3 different modes supported:
- * ser0 on PB (Bundy), ser1 on PB (Lisa) and ser2 on PA (Bundy)
- * Fixed DEF_TX value that caused the serial transmitter pin (txd) to go to 0 when
- * closing the last filehandle, NASTY!.
- * Added break generation, not tested though!
- * Use IRQF_SHARED when request_irq() for ser2 and ser3 (shared with) par0 and par1.
- * You can't use them at the same time (yet..), but you can hopefully switch
- * between ser2/par0, ser3/par1 with the same kernel config.
- * Replaced some magic constants with defines
- *
