Subject: [PATCH 0/4] Improve Rockchip VOP2 display modes handling on RK3588
 HDMI1

As a followup to getting basic HDMI1 output support [1] merged upstream,
make use of the HDMI1 PHY PLL to provide better VOP2 display modes
handling for the second HDMI output port on RK3588 SoC, similarly to
what has been achieved recently for HDMI0 [2].

Additionally, enable HDMI1 output on Rockchip RK3588 EVB1.
