Subject: [PATCH 6.13 310/414] arm64: dts: exynos: gs101: disable pinctrl_gsacore node

6.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Griffin <peter.griffin@...aro.org>

commit 168e24966f10ff635b0ec9728aa71833bf850ee5 upstream.

gsacore registers are not accessible from normal world.

Disable this node, so that the suspend/resume callbacks
in the pinctrl driver don't cause a Serror attempting to
access the registers.

Fixes: ea89fdf24fd9 ("arm64: dts: exynos: google: Add initial Google gs101 SoC support")
