Subject: [PATCH 2/2] arm64: dts: ti: k3-am654-base-board: Add MMC/SD support
Date: Fri, 7 Dec 2018 14:12:33 +0530 [thread overview]
Message-ID: <20181207084233.13700-3-faiz_abbas@ti.com> (raw)
In-Reply-To: <20181207084233.13700-1-faiz_abbas@ti.com>
On the am654x-evm, sdhci0 node is connected to an eMMC while sdhci1
is connected to an SD card slot. Add nodes and pinmuxes for the same.
