Subject: [cip-dev] [PATCH 4.4.y-cip 09/11] cpufreq: dt: Don't use generic platdev driver for ti-cpufreq platforms
Date: Wed,  9 Sep 2020 12:42:31 +0800	[thread overview]
Message-ID: <20200909044233.4115-10-wens@csie.org> (raw)
In-Reply-To: <20200909044233.4115-1-wens@csie.org>

From: Dave Gerlach <d-gerlach@ti.com>

commit 051bd84bb45bc994b7d762467f60b3bd0c7aa6bc upstream.

Some TI platforms, specifically those in the am33xx, am43xx, dra7xx, and
am57xx families of SoCs can make use of the ti-cpufreq driver to
selectively enable OPPs based on the exact configuration in use. The
ti-cpufreq is given the responsibility of creating the cpufreq-dt
platform device when the driver is in use so drop am33xx and dra7xx
from the cpufreq-dt-platdev driver so it is not created twice.

[wens@csie.org: Backport to pre generic platdev driver]
Signed-off-by: Chen-Yu Tsai (Moxa) <wens@csie.org>

I kept the original patch subject to make it easier for scripts to match
against upstream patches.
