Q7_THRM# pin is connected to a diode on the module which is used
as a level shifter, and the pin have a pull-down enabled by
default. We need to configure it to internal pull-up, other-
wise whenever the pin is configured as INPUT and we try to
control it externally the value will always remain zero.

@Heiko I think this may match the criteria for stable backports?

at least patch1 does ... it definitly should have a Fixes tag though.



Fixes: 2c66fc34e945 ("arm64: dts: rockchip: add RK3399-Q7 (Puma) SoM")

I assume, since this issue existed since the introducing commit.

Cheers,
Quentin
