On Qualcomm SoCs, certain branch clocks either need to be always-on, or
should be if you're interested in touching some part of the hardware.
Using CLK_IS_CRITICAL for this purpose sounds like a genius idea,
however that messes with the runtime pm handling - if a clock is
marked as such, the clock controller device will never enter the
"suspended" state, leaving the associated resources online, which in
turn breaks SoC-wide suspend.
This series aims to solve that on a couple SoCs that I could test the
changes on and it sprinkles some runtime pm enablement atop these drivers.
