Subject: [PATCH 2/2] ARM: dts: imx8mm-beacon: add UHS and HS400/HS400ES properties
Date: Wed, 30 Dec 2020 08:14:20 -0600 [thread overview]
Message-ID: <20201230141421.2860212-2-aford173@gmail.com> (raw)
In-Reply-To: <20201230141421.2860212-1-aford173@gmail.com>
i.MX8M Mini can provide support for high speed grades in the
usdhc controllers.
On the imx8mm-beacon-kit, the sdhc2 hosts a microSD card, and
sdhc3 hosts an eMMC capable of HS400ES.
In order to toggle this mode in SPL, the reg_usdhc2_vmmc must
be available in SPL. Add all these flags to
imx8mm-beacon-kit-u-boot.dtsi
