mmc: slot-gpio: Add GPIO descriptor based CD GPIO API

2014-03-17T13:12:00Z

Add functions to request a CD GPIO using the GPIO descriptor API. Note that the new request function is paired with mmc_gpiod_free_cd() not mmc_gpio_free_cd(). Note also that it must be called prior to mmc_add_host() otherwise the caller must also call mmc_gpiod_request_cd_irq().

mmc: core: Add ignore_crc flag to __mmc_switch

2014-02-23T15:40:30Z

Instead of handle specific adaptations, releated to certain switch operations, inside __mmc_switch, push this to be handled by the caller instead. Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: core: Rename cmd_timeout_ms to busy_timeout

2014-02-23T15:40:26Z

To better reflect that the cmd_timeout_ms is directly related to the busy detection timeout, let's rename it. Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: core: Rename max_discard_to to max_busy_timeout

2014-02-23T15:40:08Z

Rename host->max_discard_to to host->max_busy_timeout, to reflect that it tells the mmc core layer about the maximum supported busy detection timeout by the host. This timeout is at the moment only applicable to erase/trim/discard commands. By the renaming we provide the option of make use of it for other commands that cares about busy detection. In other words, those commands that wants an R1B response, like for example the mmc switch command. Do note that the max_busy_timeout is supposed to be specified only by hosts supporting MMC_CAP_WAIT_WHILE_BUSY. Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: core: Enable MMC_CAP2_CACHE_CTRL as default

2014-02-14T03:58:49Z

There are no reason to why the use of a non-volatile internal eMMC cache should be controlled by a host cap. Instead let's just enable it if the eMMC card supports it. Signed-off-by: Ulf Hansson Acked-by: Seungwon Jeon Signed-off-by: Chris Ball

mmc: core: Use mmc_flush_cache() during mmc suspend

2014-02-14T03:58:41Z

Earlier we disabled the cache during suspend, which meant a flush was internally at the eMMC performed as well. To simplify code we can make use of the mmc_flush_cache(), during mmc suspend, which makes the mmc_cache_ctrl() redundant so then we can remove it.

mmc: core: Remove unnecessary validations for bus_ops callbacks

2014-02-14T03:58:23Z

Due to the removal of the Kconfig option MMC_UNSAFE_RESUME, several validations of a present bus_ops callback became redundant. Let's remove these. Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: core: Use MMC_UNSAFE_RESUME as default behavior

2014-02-14T03:58:15Z

Invoking system suspend or shutdown without using the Kconfig option MMC_UNSAFE_RESUME, did trigger an ungraceful power cut of the card. To improve the situation, change the behavior to always make use of the available bus_ops callbacks that handles system suspend and shutdown properly. By changing the behavior MMC_UNSAFE_RESUME becomes redundant, so lets's remove it. Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: Do not call get_cd for non removable cards

mmc: core: Remove deprecated mmc_suspend|resume_host APIs
