Subject: arm64: tegra: Enable SDHCI controllers on P3110
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=80fdf7b426f1c37571b68a4494fb72a7a73a31fd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm64: tegra: Enable SDHCI controllers on P3110

The P3110 processor module wires one of the SDHCI controllers to an on-
board eMMC and exposes another set of SD/MMC signals on the connector to
support an external SD/MMC card. A third controller is connected to the
SDIO pins of an M.2 KEY E connector.
