Subject: [PATCH 07/10] mmc: sdhci: am654: Use quirk instead of custom set_power()
Date: Fri, 6 Mar 2020 11:38:52 +0100 [thread overview]
Message-ID: <20200306103857.23962-8-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200306103857.23962-1-nsaenzjulienne@suse.de>
With the introduction of SDHCI_QUIRK2_SET_BUS_VOLTAGE there is no need
to use a custom set_power() implementation as the quirk takes care of
configuring the bus voltage register even when powering trough a
regulator.
