[PATCH 0/4] drm/vc4: hdmi: Firmware clocks cleanup

Hi,

In order to accomodate the Pi0-3 using the clk-bcm2835 and the Pi4 using the
clk-raspberrypi clock drivers for the HDMI clocks, we piled a number of
workarounds over the years.

Since 6.2, we've switched the Pi0-3 to the clk-raspberrypi driver, so we can
now remove those workarounds.

Let me know what you think,
Maxime
