From c981d67a0444cf31e5a16fe4be79d785eb182385 Mon Sep 17 00:00:00 2001 From: Alexandru Gagniuc Date: Wed, 9 Sep 2020 16:54:02 -0500 Subject: [PATCH] mmc: stm32_sdmmc2: Use mmc_of_parse() to read host capabilities mmc_of_parse() can populate the 'f_max' and 'host_caps' fields of struct mmc_config from devicetree. The same logic is duplicated in stm32_sdmmc2_probe(). Use mmc_of_parse(), which is more generic.
