[RESEND PATCH 0/3] Misc bug fixes in mtk power domain driver

[Enric Balletbo i Serra]

This series, originally sent by Bilal Wasim [1], initially broke my
display in mainline (no gpu driver). The problem was not in the series
itself, and, after [2], this series works as expected. I was able to go
to the UI with and without the imgtec gpu driver on my Acer Chromebook
R13 (elm). Hence I rebased on top of mainline and resend it to take into
account for next merge window.

Best regards,
  Enric

[RESEND PATCH 3/3] arm64: dts: mediatek: mt8173: Add domain supply for mfg_async

[Enric Balletbo i Serra]

From: Bilal Wasim <Bilal.Wasim@imgtec.com>

da9211 regulator needs to be enabled before enabling the mfg_async power
domain. Otherwise the subdomain is not enabled and causes failure in
imgtec gpu driver boot.

Add the "domain-supply" property to the "mfg_async" node in DT.
