Subject: [PATCH RESEND v1 1/2] arm64: dts: qcom: lemans-evk: Move SD card support to overlay
Date: Wed, 26 Aug 2026 17:02:05 +0530 [thread overview]
Message-ID: <20260826113206.488991-2-monish.chunara@oss.qualcomm.com> (raw)
In-Reply-To: <20260826113206.488991-1-monish.chunara@oss.qualcomm.com>
The lemans EVK board supports either eMMC or SD-card, but only one can
be active at a time.
Move the SDHC node for SD card into a dedicated device tree overlay.
This decoupling allows the storage medium to be selected dynamically by
applying the appropriate overlay for either SD card or eMMC support.
