* omap_hsmmc: Board-specific TWL4030 MMC power initializationsPaul Kocialkowski2014-12-04-6/+1
| | | | | | | | | | | | Boards using the TWL4030 regulator may not all use the LDOs the same way (e.g. MMC2 power can be controlled by another LDO than VMMC2). This delegates TWL4030 MMC power initializations to board-specific functions, that may still call twl4030_power_mmc_init for the default behavior.

* omap: hsmmc: assume cd gpio is active lowIgor Grinberg2014-11-06-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Switch the default CD GPIO polarity to active low. The current hsmmc driver assumption that the CD GPIO is active high, but in the real hardware, usually the opposite holds. The usual SD card socket has a mechanical switch which is grounded as soon as a card is inserted. Of course there might be some board logic which inverts the signal, but as far as current users are concerned, there is no such logic. Current U-Boot users either not using the CD functionality, or have a different way (e.g. external to SoC GPIO controller) for checking the card presence. This patch also brings the polarity assumption in line with the Linux kernel and adds appropriate comments. This patch also might spare issues once the TWL GPIO driver will be converted to the DM.

* mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou2014-03-24-23/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* ARM: OMAP: Enable 8-bit eMMC access for OMAP4/5/DRA7xxLubomir Popov2013-09-17-3/+14
| | | | | | | | | | | | | | | Enable 8-bit host capability for HSMMC2 and/or HSMMC3. CONFIG_HSMMC2_8BIT (for OMAP4/5/DRA7xx) and/or CONFIG_HSMMC3_8BIT (for DRA7xx only) must be defined in the board header if an 8-bit eMMC device is connected to the corresponding port. Fix the "No status update" error that appeared for eMMC devices by inserting a 20 us delay between writing arguments and command. This solution has been proposed by Michael Cashwell <mboards@prograde.net>. A minor cosmetic fix in a comment as well. Signed-off-by: Lubomir Popov <lpopov@mm-sol.com>
* omap_hsmmc: omap4+/am335x: modify MMC controller internal fsm reset funcOleksandr Tyshchenko2013-09-17-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "mmc_send_cmd: timeout: No status update" error sometimes happens in omap_hsmmc driver func mmc_send_cmd() when the MMC controller card identification and selection sequence is executed for eMMC on OMAP4 boards. It happens due to incorrect execution of CMD line reset procedure for OMAP4. Because CMD(DAT) lines reset procedures are slightly different for OMAP3 and OMAP4(AM335x,OMAP5,DRA7xx). According to OMAP3 TRM: Set SRC(SRD) bit in MMCHS_SYSCTL register to 0x1 and wait until it returns to 0x0. According to OMAP4(AM335x,OMAP5,DRA7xx) TRMs, CMD(DATA) lines reset procedure steps must be as follows: 1. Initiate CMD(DAT) line reset by writing 0x1 to SRC(SRD) bit in MMCHS_SYSCTL register (SD_SYSCTL for AM335x). 2. Poll the SRC(SRD) bit until it is set to 0x1. 3. Wait until the SRC(SRD) bit returns to 0x0 (reset procedure is completed). Unfortunately, at present omap_hsmmc driver has support only for OMAP3. And as result step #2 is missing for OMAP4(AM335x,OMAP5,DRA7xx). This sometimes leads to the fact that the waiting loop which is required in step #3 does not executed, because SRC bit does not set yet (at the moment of checking a condition of a loop execution). And as a result this can cause to timeout error when sending a next command. In the particular case (working with eMMC witch do not respond to some SD specific command) due to incorrect reset sequence after command SD_CMD_SEND_IF_COND which finished with CTO flag within 64 clock cycles, the next command MMC_CMD_APP_CMD leads to a timeout error within 1s. So, extend CMD(DATA) lines reset procedure in func mmc_reset_controller_fsm() by adding the missing step #2 for OMAP4+/AM335x boards.

The previous behavior of only checking on DATI was insufficient on some cards and incorrect behavior in any case. This makes the code check for both bits being clear and makes the error print more clear as to what happened. DATI_CMDDIS is removed as it was unused elsewhere in the code and stood for 'DATI is set, cmds are disabled still'. Fix originally spotted by Peter Bigot. Tested-by: Peter A.

| | | | | | | | | | | | | | 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.

* mmc: omap: timeout counter fixNishanth Menon2010-11-19-25/+82
| | | | | | | | | | | | | | Having a loop with a counter is no timing guarentee for timing accuracy or compiler optimizations. For e.g. the same loop counter which runs when the MPU is running at 600MHz will timeout in around half the time when running at 1GHz. or the example where GCC 4.5 compiles with different optimization compared to GCC 4.4. use timer to keep track of time elapse and we use an emperical number - 1sec for a worst case timeout. This should never happen, and is adequate imaginary condition for us to fail with timeout. Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* ARMV7: OMAP: Add new mmc driver compatible with CONFIG_GENERIC_MMCSukumar Ghorai2010-10-17-0/+415
OMAP boards currently use a legacy mmc driver. This patch adds a new mmc driver which will work with the generic mmc driver in u-boot. This new driver will work with both OMAP3 and OMAP4 boards. This patch does not remove the old driver. It should remain in the tree until all boards that use it switch to the new driver.
