From: Tony Lindgren Date: Thu, 2 Jul 2020 15:45:13 +0000 (-0700) Subject: ARM: dts: Configure omap4 and 5 l4_abe for genpd and drop platform data X-Git-Tag: v5.10.7~1322^2~11^2^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0fd1594b3c339f17210c7ebfff102ad054cfcc7d;p=platform%2Fkernel%2Flinux-rpi.git ARM: dts: Configure omap4 and 5 l4_abe for genpd and drop platform data We can power off l4_abe domain when not in use when we configure it for genpd. And with that change, we can now also drop the old unused legacy platform data. Note that we also need to now use "simple-pm-bus" instead of "simple-bus" for PM runtime to get enabled for the bus.
