From 672680063420ef8c8c4e7271984bb9cc08171d29 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Wed, 12 Nov 2008 11:42:10 +0200 Subject: [PATCH] PM: OMAP3: Make sure clk_disable_unused() order is correct Current implementation will disable clocks in the order defined in clock34xx.h, at least DPLL4_M2X2 will hang in certain cases (and prevent retention / off) if clocks are not disabled in correct order. This patch makes sure the parent clocks will be active when disabling a clock.
