From 638080c37ae08fd0c44cec13d7948ca5385ae851 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Fri, 29 Apr 2011 00:36:42 +0200 Subject: OMAP2+ / PM: move runtime PM implementation to use device power domains In commit 7538e3db6e015e890825fbd9f8659952896ddd5b (PM: add support for device power domains) a better way for handling platform-specific power hooks was introduced. Rather than using the platform_bus dev_pm_ops overrides (platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM implementation over to using device power domains. Since OMAP is the only user of platform_bus_set_pm_ops(), that interface can be removed (and will be in a forthcoming patch.) [rjw: Rebased on top of a previous change modifying the handling of power domains by the PM core so that power domain callbacks take precendence over subsystem-level PM callbacks.] Signed-off-by: Kevin Hilman Acked-by: Grant Likely Signed-off-by: Rafael J.
