clk: bcm: rpi: Add disp clock
|
|
|
|
BCM2712 has an extra clock exposed by the firmware called DISP, and used
|
|
by (at least) the HVS. Let's add it to the list of clocks to register in
|
|
Linux.

clk: bcm: rpi: Add the BCM283x pixel clock.
|
|
|
|
The clk-bcm2835 handling of the pixel clock does not function
|
|
correctly when the HDMI power domain is disabled.
|
|
|
|
The firmware supports it correctly, so add it to the
|
|
firmware clock driver.
