From: Faiz Abbas Date: Mon, 10 Jun 2019 19:13:31 +0000 (+0530) Subject: arm64: dts: k3: Sync sdhci0 node from kernel and change driver name X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3a1a0dfc395e9f09e18fc103383e55d59c63f263;p=u-boot.git arm64: dts: k3: Sync sdhci0 node from kernel and change driver name Sync the sdhci0 node from kernel. This changes the compatible that is required to be there in the driver. Change the same for the SD card node which is not yet supported in kernel. This also syncs the main_pmx0 node as a side effect. Also change the name of the driver to match the compatible in kernel.
