Thu Apr 18 07:17:04 PDT 2024


- Add aliases for each display components to help display drivers.
- Add the Display Pulse Width Modulation (DISP_PWM) to provide PWM signals
  for the LED driver of mobile LCM.
- Add the MIPI Display Serial Interface (DSI) PHY support. (up to 4-lane
  output)
- Add the display mutex support.
- Add the following display component support:
  - OVL0 (Overlay)
  - RDMA0 (Data Path Read DMA)
  - Color0
  - CCorr0 (Color Correction)
  - AAL0 (Adaptive Ambient Light)
  - GAMMA0
  - Dither0
  - DSI0 (Display Serial Interface)
  - RDMA1 (Data Path Read DMA)
  - DPI0 (Display Parallel Interface)
