mmc: Add support for wait_dat0 callback

2022-06-15T06:39:56Z

There is no wait_dat0 mmc ops, causing operations waiting for data line state change (e.g mmc_switch_voltage) to fallback to a 250ms active delay. mmc_ops still used when DM_MMC is not enabled, which is often the case for SPL. The result can be unexpectly long SPL boot time. This change adds support for wait_dat0() mmc operation. Signed-off-by: Loic Poulain Reviewed-by: Jaehoon Chung

bootstd: mmc: Add a bootdev driver

2022-04-25T14:00:04Z

Add a bootdev driver for MMC. It mostly just calls the bootdev helper function. Add a function to obtain the block device for an MMC controller. Fix up the comment for mmc_get_blk_desc() while we are here. Signed-off-by: Simon Glass

doc: replace @return by Return:

mmc: unconditionally define mmc_deinit()

2022-01-12T00:56:40Z

We want to replace '#ifdef' by 'if (IS_ENABLED(CONFIG_...))' in our code. Therefore functions should be defined unconditionally even if they are not implemented. Signed-off-by: Heinrich Schuchardt Acked-by: Peng Fan Reviewed-by: Jaehoon Chung

mmc: Add support for enumerating MMC card in a given mode using mmc command

2021-09-10T10:17:04Z

Add support for enumerating MMC card in a given mode using mmc rescan and mmc dev commands. The speed mode is provided as the last argument in these commands and is indicated using the index from enum bus_mode in include/mmc.h. A speed mode can be set only if it has already been enabled in the device tree. Signed-off-by: Aswath Govindraju Reviewed-by: Jaehoon Chung Tested-by: Jaehoon Chung

mmc: mmc_get_op_cond: Allow quiet detection of eMMC

2021-07-15T08:53:11Z

Add a new 'quiet' argument to mmc_get_op_cond() function which avoids printing error message when SD/eMMC card is not detected. Espressobin and mx6cuboxi boards use this function for detecting presence of eMMC and therefore it is expected and normal that eMMC does not have to be connected. So error message "Card did not respond to voltage select!" should be skipped in this case as it is not an error. Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese Acked-by: Jaehoon Chung

mmc: fix response timeout after switch command

2021-02-19T07:04:15Z

After issuing the switch command: Wait until 'current state' of the card status becomes 'tran'. This prevents from response timeout at the next command because of 'current state' = 'data'. Signed-off-by: Stefan Bosch Reviewed-by: Jaehoon Chung
