Subject: [PATCH] ASoC: ak5558: correct reset polarity
Date: Tue, 13 Apr 2021 14:06:31 +0800 [thread overview]
Message-ID: <1618293991-6611-1-git-send-email-shengjiu.wang@nxp.com> (raw)
Reset (aka power off) happens when the reset gpio is made active.
Change function name to ak5558_reset to match devicetree property
"reset-gpios".
