From 3a5b187b5c03eff681d4e41823313dfa28dfe845 Mon Sep 17 00:00:00 2001 From: Kaustabh Chakraborty Date: Fri, 17 Oct 2025 20:54:07 +0530 Subject: [PATCH] mmc: dw_mmc: do not skip dwmci_setup_bus() for same non-zero clock frequency In dwmci_setup_bus(), if the requested frequency is equal to the current frequency, the function is returned, assuming no changes are required in associated registers. On certain SD cards, skipping in such situations may result in a timeout errors during MMC initialization. Due to the lack of documentation, the cause is unknown, but removing said check seems to fix the issue.
