Subject: arm/dt: Tegra: Add support-8bit to SDHCI nodes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6111d50c5885f6ba00dc935e44bcbbcd63b3915d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

arm/dt: Tegra: Add support-8bit to SDHCI nodes

For Seaboard's internal eMMC, this makes the difference between a
5.5MB/s and 10.2MB/s transfer rate. On Harmony, there wasn't any
measurable difference on my cheap/slow ~2MB/s card.
