[PATCH v2 0/5] Improve Rockchip VOP2 display modes handling on RK3588 HDMI1

[Cristian Ciocaltea]

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].

Please note Heiko's fix [3] in of_clk_get_hw_from_clkspec() is also
required for boards that do not provide HDMI0 output, that is to ensure
devm_clk_get_optional() returns NULL instead of ERR_PTR(-EPROBE_DEFER),
which otherwise would put rockchip-drm module in a permanent deferred
probe mode.

Additionally, enable HDMI1 output on Rockchip RK3588 EVB1.

Changes in v2:
- Make use of dev_err_probe() for handling failures when trying to get
  pll_hdmiphy1 optional clock (Sebastian)
- Add a new patch to replace drm_err() calls in vop2_bind() and
  vop2_create_crtcs() with dev_err_probe(), to simplify error handling
  and improve consistency, along with some related fixes
