I propose this patch instead. What do you think? Care to reply with a Reviewed-by: and/or Tested-by: ? - Paul From: Paul Walmsley <paul@xxxxxxxxx> Date: Sat, 12 Feb 2011 17:36:38 -0600 Subject: [PATCH] OMAP2+: clock: autoidle as many clocks as possible in OMAP2+-common PM code Attempt to enable autoidle for as many clocks as possible in the OMAP2+-common PM code. Currently, this only enables DPLL autoidle for OMAP3/4 DPLLs; but it should also eventually enable autoidle for other clocks and the OMAP2 DPLL/APLLs. Based on a patch by Rajendra Nayak <rnayak@xxxxxx> that did this in the pm34xx.c/pm44xx.c code, rather than the common PM code.
