This patch series adds DRM support for the Amlogic S4-series SoCs.
Compared to the Amlogic G12-series, the S4-series introduces the following changes:
1 The S4-series splits the HIU into three separate components: `sys_ctrl`, `pwr_ctrl`, and `clk_ctrl`.
As a result, VENC and VCLK drivers are updated with S4-specific compatible strings to accommodate these changes.
2 The S4-series secures access to HDMITX DWC and TOP registers,
requiring modifications to the driver to handle this new access method.
3 The register addresses for the video1 and video2 planes have been updated in the S4 hardware,
and the DRM driver has been adapted accordingly.
4 The OSD, VIU, and VPP components remain unchanged and are consistent with the G12-series.
Thanks a lot for this high quality changeset, happy to see DRM support for a new SoC !
I'll review it carefully next week.
