Subject: [PATCH v5 01/14] mmc: sdhci-omap: Fix when capabilities are obtained from SDHCI_CAPABILITIES reg
Date: Fri, 27 Apr 2018 17:17:10 +0530 [thread overview]
Message-ID: <20180427114723.2687-2-kishon@ti.com> (raw)
In-Reply-To: <20180427114723.2687-1-kishon@ti.com>
sdhci_omap_config_iodelay_pinctrl_state() requires caps and caps2 to be
initialized (speed mode capabilities like UHS/HS200) before it is
invoked. While mmc_of_parse() initializes caps/caps2 if capabilities is
populated in device tree, it will remain uninitialized for capabilities
obtained from SDHCI_CAPABILITIES register.
Fix sdhci_omap_config_iodelay_pinctrl_state() to be used even while
getting the capabilities from SDHCI_CAPABILITIES register by invoking
sdhci_setup_host() before sdhci_omap_config_iodelay_pinctrl_state().
