Hm, why reserved ranges are in SoC?
As the gpio is forbidden on all ipq9574 boards, we have added it in SoC
Why it is forbidden on all boards? I guess it depends on the firmware
and this can differ, can't it?
This GPIO is protected and used by the TZ firmware and is forbidden on all the boards & firmware
If it's protected on *all* boards and *all* firmwares (for any
good reason that you probably have internally), perhaps it
would be better to describe it in the .c driver.. wdyt?
Sure, okay. Will add the gpio to reserved_gpios entry in the pinctrl driver
