Subject: [PATCH 00/12] soc: mediatek: pm-domains: Add new driver for SCPSYS power domains controller

Dear all,

This is a new driver with the aim to deprecate the mtk-scpsys driver.
The problem with that driver is that, in order to support more Mediatek
SoCs you need to add some logic to handle properly the power-up
sequence of newer Mediatek SoCs, doesn't handle parent-child power
domains and need to hardcode all the clocks in the driver itself. The
result is that the driver is getting bigger and bigger every time a
new SoC needs to be supported.

All this information can be getted from a properly defined binding, so
can be cleaner and smaller, hence, we implemented a new driver. For
now, only MT8173 and MT8183 is supported but should be fairly easy to
add support for new SoCs.

Best regards,
  Enric
