Subject: [PATCH 1/8] ARM: OMAP2+: Remove unused wakeup_cpu
Date: Wed,  9 Oct 2019 17:12:17 -0700	[thread overview]
Message-ID: <20191010001224.41826-2-tony@atomide.com> (raw)
In-Reply-To: <20191010001224.41826-1-tony@atomide.com>

After commit 32d174ed1bd7 ("ARM: OMAP4: MPUSS PM: remove unnecessary
shim functions for powerdomain control") this is no longer used.

The code continues execution after context restore on the same CPU,
so we can just use pm_info->pwrdm.
