From 8505147403584f322bf1cb66b1c796bc11f29ad4 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Thu, 16 Jul 2020 14:37:26 +0530 Subject: mmc: msm_sdhci: Use mmc_of_parse for setting host_caps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since the introduction of 'get_cd' callback in sdhci core, dragonboard410c's MMC interface is broken. It turns out that 'get_cd' callback checks for the host_caps for validating the chip select. And since the msm_sdhci driver is not parsing the host_caps from DT, not all of the cababilities are parsed properly. This results in the MMC interfaces to be broken. Hence, fix this by adding a call to 'mmc_of_parse' during driver probe.
