+Subject: arm64: dts: rockchip: enable internal pull-up for Q7_THRM# on RK3399 Puma
+
+From: Iskander Amara <iskander.amara@theobroma-systems.com>
+
+commit 0ac417b8f124427c90ec8c2ef4f632b821d924cc upstream.
+
+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.
