Subject: [PATCH 0/4] Add clock provider support to Rockchip RK3588 HDMI TX
 PHY

The HDMI PHY PLL can be used as an alternative clock source to RK3588
SoC CRU. Since it provides more accurate clock rates, it can be used by
VOP2 to improve display modes handling, such as supporting non-integer
refresh rates.

The first two patches in the series provide a couple of fixes and
improvements to the existing HDPTX PHY driver, while the next two add
the necessary changes to support the clock provider functionality.
