Subject: [PATCH v2 1/4] arm64: dts: qcom: ipq9574: Add gpio details for eMMC
Date: Fri, 23 Jan 2026 17:30:13 +0530 [thread overview]
Message-ID: <20260123120016.3671812-2-varadarajan.narayanan@oss.qualcomm.com> (raw)
In-Reply-To: <20260123120016.3671812-1-varadarajan.narayanan@oss.qualcomm.com>
The RDP433 has NAND and eMMC variants. Presently, only NAND variant is
supported. To enable support for eMMC variant, add the relevant GPIO
related information.
