Subject: [PATCH V2 2/2] arm64: dts: qcom: Enable SD card for Shikra EVK
Date: Tue, 30 Jun 2026 22:27:00 +0530	[thread overview]
Message-ID: <20260630165700.1886608-3-monish.chunara@oss.qualcomm.com> (raw)
In-Reply-To: <20260630165700.1886608-1-monish.chunara@oss.qualcomm.com>

Enable SD card for Shikra CQS, CQM and IQS EVK variants. Configure the
vmmc/vqmmc regulators and gpio-based card detection for each board
variant.
