[PATCH v1] arm64: dts: qcom: shikra: Unreserve GPIOs 14-17 blocking SPI5 access

Posted by Xueyao An 1 month, 1 week ago

GPIOs 14-17 were previously reserved in the tlmm gpio-reserved-ranges,
preventing Linux from accessing SPI5. Since there is no TZ use case for
these pins on Linux, they can be safely unreserved. Removing them from
the reserved list across all three Shikra EVK variants (CQM, CQS, IQS)
resolves the SPI5 access issue.

Why would Linux need to access SPI5 if there is no user of it? Or is
there, but you skipped it?
