Hi Mark, Stefan,

Here's a series addressing the current bug that has been reported for the
RaspberryPi3, where booting without an HDMI monitor attached and with vc4
compiled as a module will lead to a stuck system when the module is loaded.

This is due to the HSM clock not being initialized by anyone, and thus not
being functional once we start accessing the HDMI registers.

The first patch will fix this, and the second will make sure we avoid that
situation entirely in the future. This has been tested with 5.19.12. Earlier
versions might need a backport of 88110a9f6209 ("clk: bcm2835: fix
bcm2835_clock_choose_div").
Could you test/review this?

Looks good to me:

Thanks
Maxime
