Thanks for that, it's working now. I didn't realise you had to apply the

We had several issues with the system PM support.
1) It were depending on CONFIG_PM_RUNTIME.
2) It unnecessarily tracked the suspend state in a flag.
3) If userspace through sysfs prevents runtime PM operations, could
cause the device to stay in low power after a system PM resume, which
is not refl
The driver depended on CONFIG_PM_RUNTIME to be functional, which isn't
necessary.
The solution to the above is to enable all runtime PM resourses during
probe and update the device's runtime PM status to active.
Since driver core invokes pm_request_idle() after ->probe(), unused gsc
devices will
We want to make sure that the clock is fully gated after ->remove(). To
do this, we need to bring the device into full power and not only
unprepare the clock, but also disable it.

Instead of having separate functions that fecthes, prepares and
unprepares the clock, let's encapsulate this code into ->probe().
This makes error handling easier and decreases the lines of code.
