mmc: sdhci: iproc: Add custom set_power() callback for bcm2711 (f87391ee) · Commits · 戴 / test

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. Signed-off-by:
