From f07c15c16a1bbdf8eaa9ad79af774e31948bcba3 Mon Sep 17 00:00:00 2001 From: Varadarajan Narayanan Date: Thu, 16 Apr 2026 10:41:51 +0530 Subject: [PATCH] mmc: msm_sdhci: Use max-frequency to get clock rate msm_sdc_clk_init() uses clock-frequency to get the clock rate for SDC clocks. However, the DT files seem to use max-frequency for the same. Since msm_sdc_clk_init() doesn't find clock-frequency in the DT, it sets 201500000 as the clock rate and this results in timeout errors on IPQ platforms. Additionally, clock-frequency is not DT bindings compliant. Hence, get clock rate using DT bindings compliant max-frequency.
