From a672a3f2f0221bc56e94d6508e3b3fc74442065b Mon Sep 17 00:00:00 2001 From: Jesse Taube Date: Thu, 17 Mar 2022 16:23:45 +0000 Subject: [PATCH] ARM: dts: suniv: F1C100: add MMC controllers The F1C100 series contains two MMC controllers, where the first one is typically connected to an (micro)SD card slot (as this is the one the BROM is able to boot from). Describe the two controllers in the SoC .dtsi. We also add the pinctrl description for MMC0, since this is the only pin set supporting that function anyway, and SD cards are very common across boards.
