Subject: [PATCH v1] arm64: dts: qcom: shikra: Unreserve GPIOs 14-17 blocking SPI5 access
Date: Thu, 20 Aug 2026 16:53:47 +0800 [thread overview]
Message-ID: <20260820085347.822-1-xueyao.an@oss.qualcomm.com> (raw)
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.
