[PATCH RFC v2 0/4] phy: hisi-inno-phy: add support for hi3798mv200-usb2-phy

[Yang Xiwen via B4 Relay]

This should be considered a dirty hack. The proper solution would be
extracting write_reg logic to a separate regmap driver. Leaving only
"write BIT(2) to address 0x6" to the PHY driver.

The initial commit is already doing things wrong. The following patches
adding hi3798mv100 support is also very confusing. The name of the
enumeration "PHY_TYPE_x" is very misleading as if it's the phy which is
different across SoCs. But actually it's the bus (i.e. how to write to a
given address) which is different, not the PHY.

Changes in v2:
- rewrite commit msg to show why hisilicon,hi3798mv100-usb2-phy is added
  during YAML convertion.
- split required: to multiple line
- add allOf to wrap if:
- remove perictrl wrapper and the second phy in the example
- tested the binding both for mv200 and cv200 dts. fix some silly
  errors.
Above all are suggested by Krzysztof
- use reset_control_array_* APIs to ensure all resets are controlled
- Link to v1: https://lore.kernel.org/r/20240216-inno-phy-v1-0-1ab912f0533f@outlook.com
