Subject: [PATCH v5 0/5] phy: hisi-inno-phy: add support for
 hi3798mv200-usb2-phy

This should be considered a 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.

A proper fix should be implemented later.
