[PATCH v1] arm64: dts: qcom: HAMOA-IOT-SOM: Unreserve GPIOs blocking SPI11 access

Posted by Xueyao An 1 month, 2 weeks ago

GPIOs 44-47 were previously reserved, preventing Linux from accessing
SPI11 (qupv1_se3). Since there is no TZ use case for these pins on Linux,
they can be safely unreserved. Removing them from the reserved list
resolves the SPI11 access issue for Linux.

Lowercase the hamoa-iot-som in subject line.

With that fixed:
