The MAX7802 PMIC has a Real-Time-Clock (RTC) with two alarms. This patch adds support for the RTC and is based on a driver added by Simon Glass to the Chrome OS kernel 3.8 tree. Signed-off-by: Javier Martinez Canillas <redacted> Reviewed-by: Krzysztof Kozlowski <redacted>
Would it be appropriate to gather Simon's signoff?
