…or fast PWM" This reverts commit 99faf47. Signed-off-by: Michał Stasiak <[email protected]>
Added clock control api for global hsfll used in fast PWM120 driver. Upstream PR #: 82133 Signed-off-by: Michał Stasiak <[email protected]>
Fast PWM120 prevents GPIO from driving pin with low/high state when PWM duty is 0% or 100%. Idleout feature needs to be used. It can be configured when PWM is disabled and works while it is enabled. Upstream PR #: 83652 Signed-off-by: Michał Stasiak <[email protected]>

Clock requesting in case of PWM120 needed fixes to control whether clock is requested when entering s2ram.
Since GPIO cannot drive pins used by fast PWM, PWM`s idleout mechanism needs to be used to cover the case of 0% and 100% duty cycle.
