Subject: [PATCH v2 09/11] mmc: sdhci: iproc: Add custom set_power() callback for bcm2711
Date: Fri, 6 Mar 2020 18:44:11 +0100 [thread overview]
Message-ID: <20200306174413.20634-10-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200306174413.20634-1-nsaenzjulienne@suse.de>
The controller needs a valid bus voltage in its power register
regardless of whether an external regulator is taking care of the power
supply.
The sdhci core already provides a helper function for this,
sdhci_set_power_and_bus_voltage(), so create a bcm2711 specific 'struct
sdhci_ops' which makes use of it.
