Loongson boards using various external display bridges to extend output
display interface. To complete the support, we have to introduce VBIOS(
or DT/ACPI support) and display bridge drivers.

Sui Jingfeng (8):
  drm/loongson: Introduce a minimal support for Loongson VBIOS
  drm/loongson: Introduce a drm bridge driver for it66121 HDMI
    transmitter
  drm/loongson: Allow attach drm bridge driver by calling
    lsdc_output_init()
  drm/loongson: Started to attach display bridge driver for LS7A1000
  drm/loongson: Using vbios for the LS7A2000 output initialization
  drm/loongson: Clean up the output part of LS7A2000
  drm/loongson: Support to infer DC reversion from CPU's PRID value
  drm/loongson: Add support for the display subsystem in LS2K2000
