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.
