* mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou2014-03-241-18/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
* mmc: Convert mmc struct's name array to a pointerPantelis Antoniou2014-03-241-1/+1
| | | | | | | Using an array is pointless; even more pointless (and scary) is using sprintf to fill it without a format string. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>
* mmc: Remove ops from struct mmc and put in mmc_opsPantelis Antoniou2014-03-241-6/+7
| | | | | | | | | | | | | | | | | Remove the in-structure ops and put them in mmc_ops with a constant pointer to it. This makes the mmc structure smaller as well as conserving code space (in theory). All in-tree drivers are converted as well; this is done in a single patch in order to not break git bisect. Changes since V1: Fix compilation b0rked issue on omap platforms where OMAP_GPIO was not set. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

* mmc: Implement card detection.Thierry Reding2012-01-081-0/+1
| | | | | | | | | | | Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.

* MMC: make b_max unconditionalJohn Rigby2011-04-291-2/+1
| | | | | | | | | | | | | | Make existing field b_max field in struct mmc unconditional and use it instead of CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_bread and mmc_bwrite. Initialize b_max to CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_register if it has not been initialized by the hw driver. Initialize b_max to 0 in all callers to mmc_register.

* Davinci MMCSD SupportSandeep Paulraj2011-02-021-0/+404
Added support for MMC/SD cards for Davinci. This feature is enabled by CONFIG_DAVINCI_MMC and is dependant on CONFIG_MMC and CONFIG_GENERIC_MMC options. This is tested on DM355 and DM365 EVMs with both the available mmc controllers. Signed-off-by: Alagu Sankar <alagusankar@embwise.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
