Subject: [PATCH 00/11] Subject: [PATCH 00/11] Add DRM support for Amlogic
 S4

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.
