mmc: fsl_esdhc_imx: Update compatible string for imx8m

2019-11-05T03:21:25Z

To enable HS400(ES) and UHS for imx8m platforms, update the driver data to share with imx8qm esdhc_soc_data. Signed-off-by: Peng Fan

mmc: fsl_esdhc_imx: drop redundant clock settings

2019-11-05T03:21:25Z

During mmc initialization, there are several calls to mmc_set_clock and mmc_set_ios. When mmc_power_off, the mmc->clock will be set, but the imx driver will use 400KHz. So the following calls to mmc_set_ios will set the clock several times which is redundant in fsl_esdhc_imx driver. So let's simplify to remove redundant clock settings. Signed-off-by: Peng Fan

mmc: fsl_esdhc: clean up DM and non-DM code

2019-11-05T03:21:25Z

Make DM and non-DM code clear using below structure. #if !CONFIG_IS_ENABLED(DM_MMC) #else #endif Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: always check write protect state

2019-11-05T03:21:25Z

The QorIQ eSDHC on all platforms supports checking write protect state through register bit. So check it always. Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: drop redundant code for non-removable feature

2019-11-05T03:21:25Z

Drop redundant code for non-removable feature. "non-removable" property has been read in mmc_of_parse(). Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: convert to use fsl_esdhc_get_cfg_common()

2019-11-05T03:21:25Z

The fsl_esdhc_init() was actually to get configuration of mmc_config. So rename it to fsl_esdhc_get_cfg_common() and make it common for both DM_MMC and non-DM_MMC. Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: clean up bus width configuration code

2019-11-05T03:21:24Z

This patch is to clean up bus width setting code. - For DM_MMC, remove getting "bus-width" from device tree. This has been done in mmc_of_parse(). - For non-DM_MMC, move bus width configuration from fsl_esdhc_init() to fsl_esdhc_initialize() which is non-DM_MMC specific. And fix up bus width configuration to support only 1-bit, 4-bit, or 8-bit. Keep using 8-bit if it's not set because many platforms use driver without providing max bus width. - Remove bus_width member from fsl_esdhc_priv structure. Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: fix voltage validation

2019-11-05T03:21:24Z

Voltage validation should be done by CMD8. Current comparison between mmc_cfg voltages and host voltage capabilities is meaningless. So drop current comparison and let voltage validation is through CMD8. Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: drop controller initialization in fsl_esdhc_init()

2019-11-05T03:21:24Z

Controller initialization is not needed in fsl_esdhc_init(). It will be done in esdhc_init() for non-DM_MMC, and in esdhc_init_common() in probe for DM_MMC. Signed-off-by: Yangbo Lu

mmc: fsl_esdhc: drop i.MX DDR support code

2019-10-29T02:09:22Z

A previous patch below adding DDR mode support was actually for i.MX platforms. Now i.MX eSDHC driver is fsl_esdhc_imx.c. For QorIQ eSDHC, it uses different process for DDR mode, and hasn't been supported. Let's drop DDR support code for i.MX in fsl_esdhc driver. 0e1bf61 mmc: fsl_esdhc: Add support for DDR mode Signed-off-by: Yangbo Lu
