[PATCH 0/2] clk: meson8b: allow the HDMI driver to manage "hdmi_sys"

[Martin Blumenstingl <martin.blumenstingl@googlemail.com>]

The "hdmi_sys" clock is driving the HDMI TX controller. The
controller's IP seems to use this clock for example to derived the DDC
clock.

Testing has shown that we can disable this clock without locking up the
system (as long as we don't read the HDMI TX registers while this clock
is disabled - this can't happen as we don't have a driver yet and once
we have one that driver will enable this clock).


Martin Blumenstingl (2):
  clk: meson8b: export the HDMI system clock
  clk: meson: meson8b: make the hdmi_sys clock tree mutable
