Describe the MT6392 PMIC and its RTC and regulator devices. This device is mostly based on MT6323 with some similarities to MT6397 and is usually found on boards using the MT8516/MT8167 SoC. Signed-off-by: Luca Leonardo Scorcia <l.scorcia@gmail.com> --- Previous version of this patch had the PMIC device declared with a fallback compatible to "mediatek,mt6323". Sashiko pointed out in [1] that it would have been wrong as the fallback device is not really compatible with the new PMIC. Since the change is significant I have not included the Reviewed-by tag that Krzysztof Kozlowski kindly provided in v9 of this patch, I hope this is the right thing. I really want to get the bindings right as they are harder to fix in later commits if the need arises.
