These QoS node are typically referenced from power domains so that the
PMU driver know what QoS to save/restore when a power domain is power
cycled.

Vendor kernel only reference the two qos_gpu nodes in it's power domains,
do you have any documentation or knowledge about what power domain the
remaining QoS are related to?

It would have been helpful to include PMU support to help understand the
QoS <-> PD relationship, on their own they do not tell us that much :-)

Jonas

I think the GPU actually is the _only_ fully switchable power-domain on the
rk3528. The other powerdomains seem to be always on, but can do this
idle-request thing.

At least that is what I'm reading from the pm-domain definitions in the
vendor-kernel, combined with a look at the pmu section of the rk3528 TRM.
