   4 Subject: [PATCH] dt: bcm283x: Change BCM283x HDMI to use firmware
   5  clock driver
   6
   7 The clk-bcm2835 handling of the pixel clock does not function
   8 correctly when the HDMI power domain is disabled.
   9
  10 The firmware supports it correctly, and the firmware clock
  11 driver now supports it, so switch the vc4-hdmi driver to use
  12 the firmware clock driver.
