[PATCH 1/4] arm64: dts: qcom: sm7325-nothing-spacewar: Add CAM fixed-regulators
From: Danila Tikhonov
Date: Mon Feb 03 2025 - 06:44:44 EST
Two regulators (GPIO 72 & 107) for the IMX766 sensor are missing here.
Without a driver, it's unclear if they're extra supplies or pwdn/power
GPIOs (labeled "custom" in the downstream kernel).
So add only those fixed regulators that are currently predictable for
camera sensors, camera EEPROMs and camera actuators.
