From b55f03ee040383416038b2bb31e5bde138b9eca2 Mon Sep 17 00:00:00 2001 From: Sam Protsenko Date: Wed, 7 Aug 2024 22:14:29 -0500 Subject: [PATCH] mmc: exynos_dw_mmc: Read upstream SDR timing properties The obsolete "samsung,timing" dts property is now split into "samsung,dw-mshc-ciu-div" (for holding the internal DW MMC divider value) and "samsung,dw-mshc-sdr-timing" (for actual timing values) in upstream Linux kernel. Rework the driver to make use of new properties instead of the old one. All affected dts files were already updated accordingly. No functional change.
