Subject: [PATCH 2/3] arm: dts: k3-j7200-main: Add support for HS400 and update delay select values for MMCSD subsystems
Date: Tue, 25 May 2021 15:08:24 +0530 [thread overview]
Message-ID: <20210525093826.10390-3-a-govindraju@ti.com> (raw)
In-Reply-To: <20210525093826.10390-1-a-govindraju@ti.com>
HS400 speed mode is now supported in J7200 SoC[1]. Therefore add
mmc-hs400-1_8v tag in sdhci0 device tree node.
Also update the delay values for various speed modes supported, based on
the revised january 2021 J7200 datasheet[2].
