[PATCH v3 3/6] mmc: pwrseq: Document optional clock for the simple power sequence

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Some WLAN chips attached to a SDIO interface, need an external clock
to be operational. Since this is very common, extend the simple MMC
power sequence DT binding to support an optional clock.
