From 1ac64c8fa124e401daf020cabd9d0bf5b032e4ec Mon Sep 17 00:00:00 2001 From: Kalle Jokiniemi Date: Wed, 22 Oct 2008 09:47:06 +0300 Subject: [PATCH] OMAP3 DSS: Fixed FIFO buffer register field sizes The size status field in DISPC_[GFX | VID1 | VID2]_FIFO_SIZE_STATUS register is 11 bits wide in OMAP3, but only 9 bits were read. Similarly, the threshold field in DISPC_[GFX | VID1 | VID2]_FIFO_THRESHOLD register is 12 bits wide, while only 9 bits were written in it. This patch extends the bit field sizes used in setup_plane_fifo to correspond to ones in OMAP3. In OMAP2 the extra bits are reserved, so no harm should come from extending the bit fields.
