Hi everyone,

There is a problem that the output does not work at a resolution
exceeding FHD. To solve this, we need to adjust the bvb clock at a
resolution exceeding FHD.

Rebased on top of next-20200708 and [1].

[1] : [PATCH v4 00/78] drm/vc4: Support BCM2711 Display Pipeline (Maxime's patchset)

Changes from v1:
  - Added dt-bindings documents
  - Change patch order, first fix driver and then device tree

Hoegeun Kwon (4):
  clk: bcm: rpi: Add register to control pixel bvb clk
  drm/vc4: hdmi: Add pixel bvb clock control
  dt-bindings: display: vc4: hdmi: Add bvb clock-names property
  ARM: dts: bcm2711: Add bvb clock for hdmi-pixel
