From 07d2aa783cd50ede621ba6e51b3017b38791f478 Mon Sep 17 00:00:00 2001 From: Kaustabh Chakraborty Date: Fri, 17 Oct 2025 20:54:14 +0530 Subject: [PATCH] mmc: exynos_dw_mmc: add compatible for exynos7870-dw-mshc-smu Exynos7870 is documented in upstream dt-schema. Add it in the U-Boot driver. Note that here it seems that Exynos7 DW MMC is perfectly compatible with Exynos7870 DW MMC. It's not always true, especially in SDIO cards where data from a 64-bit FIFO is read in two 32-bit halves [1]. Since SDIO isn't used or implemented here, it's oblivious. But upstream's schema considers that quirk, so that compatible is followed.
