Subject: [PATCH v5 1/2] arm64: dts: qcom: shikra: unreserve GPIOs 14-17
Date: Thu, 03 Sep 2026 12:48:53 +0530 [thread overview]
Message-ID: <20260903-shikra-dtpm-v5-1-e8ea3ac8a135@oss.qualcomm.com> (raw)
In-Reply-To: <20260903-shikra-dtpm-v5-0-e8ea3ac8a135@oss.qualcomm.com>
GPIOs 14-17 were previously reserved in the tlmm gpio-reserved-ranges,
preventing Linux from accessing SPI5. Removing them from the reserved
list across all three Shikra EVK variants (CQM, CQS, IQS) enables it
for dTPM usecase.
