Subject: [PATCH v2 13/17] regulator: rohm-regulator: Support SNVS HW state.
Date: Tue, 19 Jan 2021 09:27:56 +0200 [thread overview]
Message-ID: <2d01ea7101deb7430a2134af76186f78595be116.1611037866.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1611037866.git.matti.vaittinen@fi.rohmeurope.com>
The ROHM BD71815 supports setting voltage levels/regulator status
for HW-states "RUN", "SUSPEND", "LPSR" and "SNVS". Add DT parsing
helper also for SNVS state.
