Subject: Missing OMAP PM layer
Date: Sun, 24 Jan 2016 21:23:58 +0100	[thread overview]
Message-ID: <201601242123.58871@pali> (raw)

Hello,

make menuconfig allows me to choose "OMAP PM layer selection" and the 
only one option is CONFIG_OMAP_PM_NOOP "No-op/debug PM layer".

What does it mean? Power manager is noop?

I see that it has only two corresponding files in mainline kernel:
arch/arm/mach-omap2/omap-pm.h
arch/arm/mach-omap2/omap-pm-noop.c

Nokia's kernels (for N900 and N950) had also:
arch/arm/mach-omap2/omap-pm-srf.c

Can somebody explain it what happened with omap power management?

Looks like that omap-pm.h provides some API, but the only implementation 
is noop which do nothing.
