Subject: [PATCH] soc: amlogic: pm-domains: use always-on flag
Date: Mon, 21 Sep 2020 15:21:35 -0700 [thread overview]
Message-ID: <20200921222135.7145-1-khilman@baylibre.com> (raw)
Rather than use a governor to keep these domains always-on, instead
use the flag GENPD_FLAG_ALWAYS_ON. This has the same effect, but with
much lower overhead since the governor path is not used at all.
