Subject: [PATCH 1/2] arm64: dts: ti: k3-am62a-main: Add sdhci0 instance
Date: Fri, 27 Oct 2023 15:09:49 +0530	[thread overview]
Message-ID: <20231027093950.1202549-2-n-yadav@ti.com> (raw)
In-Reply-To: <20231027093950.1202549-1-n-yadav@ti.com>

Add sdhci0 DT node in k3-am62a-main for eMMC support. Droping
ITAP values as they are NA in datasheet[0] for lower speed modes.
Add mmc0 alias for sdhci0 in k3-am62a7-sk.dts.
