Subject: [PATCH 1/3] PM / Domains: Rename power state enums for genpd
Date:   Wed, 19 Aug 2020 12:40:55 +0200
Message-Id: <20200819104057.318230-2-ulf.hansson@linaro.org>

Precedence: bulk

To clarify the code a bit, let's rename GPD_STATE_ACTIVE into
GENPD_STATE_ON and GPD_STATE_POWER_OFF to GENPD_STATE_OFF.
