This patch is a drm driver for Starfive Soc JH7110, I am sending Drm driver part and HDMI driver part.
We used GEM framework for buffer management , and for buffer allocation,we use DMA APIs.
the Starfive HDMI servers as interface between a LCD Controller and a HDMI bus. A HDMI TX consists of one HDMI transmitter controller and one HDMI transmitter PHY. (Sound support is not include in this patch)
This patchset should be applied after the patchset: https://patchwork.kernel.org/project/linux-clk/cover/20230713113902.56519-1-...
V1: Changes since v1: - Further standardize the yaml file. - Dts naming convention improved. - Fix the problem of compiling and loading ko files. - Use drm new api to automatically manage resources. - Drop struct vs_crtc_funcs&vs_plane_funcs，subdivide the plane's help interface - Reduce the modifiers unused. - Optimize the hdmi driver code
