Unregister critical branch clocks + some RPM
|
expand
|
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.
