mmc: core: Report firmware version for eMMC 5.0 devices.

2014-11-10T11:40:36Z

For eMMC 5.0 compliant device, firmware version is stored in ext_csd. Report firmware as a 64bit hexa decimal. Vendor can use hexa or ascii string to report firmware version. Also add FFU related EXT_CSD register and note if the device is FFU capable. Signed-off-by: Gwendal Grignou Signed-off-by: Ulf Hansson

mmc: block: Use dev_set|get_drvdata()

2014-11-10T11:40:34Z

In most of the cases mmc_get|set_drvdata() didn't simplify code, which should be the primary reason for such macros. Let's remove them and convert to the common device_driver macros, dev_set|get_drvdata() instead. Signed-off-by: Ulf Hansson

mmc: core: Convert mmc_driver to device_driver

2014-11-10T11:40:33Z

The struct mmc_driver adds an extra layer on top of the struct device_driver. That would be fine, if there were a good reason, but that's not the case. Let's simplify code by converting to the common struct device_driver instead and thus also removing superfluous overhead. Signed-off-by: Ulf Hansson

mmc: Replace "enhanced_area_en" attribute by "partition_setting_completed"

2014-09-18T22:03:36Z

Replace ext_csd "enhanced_area_en" attribute by "partition_setting_completed". It was used whether or not enhanced user area is defined and without checks of EXT_CSD_PARTITION_SETTING_COMPLETED bit. Signed-off-by: Grégory Soutadé Signed-off-by: Ulf Hansson

mmc: implement Driver Stage Register handling

2014-09-09T11:59:07Z

Some eMMC and SD cards implement a DSR register that allows to tune raise/fall times and drive strength of the CMD and DATA outputs. The values to use depend on the card in use and the host. It might be needed to reduce the drive strength to prevent voltage peaks above the host's specification. Implement a 'dsr' devicetree property that allows to specify the value to set the DSR to. For non-dt setups the new members of mmc_host can be set by board code. This patch was initially authored by Sascha Hauer. It contains improvements authored by Markus Niebel and Uwe Kleine-König.

mmc: Correct the value of MMC_NUM_PHY_PARTITION

2014-09-09T11:59:00Z

eMMC card can support up to 7 physical partitions, including 2 boot, 1 RPMB and 4 GPs. Change MMC_NUM_PHY_PARTITION from 6 to 7, which is the correct value. Signed-off-by: Yi Sun Signed-off-by: Ulf Hansson

mmc: add support for HS400 mode of eMMC5.0

2014-05-12T22:06:06Z

This patch adds HS400 mode support for eMMC5.0 device. HS400 mode is high speed DDR interface timing from HS200. Clock frequency is up to 200MHz and only 8-bit bus width is supported. In addition, tuning process of HS200 is required to synchronize the command response on the CMD line because CMD input timing for HS400 mode is the same as HS200 mode.

mmc: rework selection of bus speed mode

2014-05-12T22:06:04Z

Current implementation for bus speed mode selection is too complicated. This patch is to simplify the codes and remove some duplicate parts. The following changes are including: * Adds functions for each mode selection(HS, HS-DDR, HS200 and etc) * Rearranged the mode selection sequence with supported device type * Adds maximum speed for HS200 mode(hs200_max_dtr) * Adds field definition for HS_TIMING of EXT_CSD Signed-off-by: Seungwon Jeon Tested-by: Jaehoon Chung Acked-by: Jaehoon Chung Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball

mmc: identify available device type to select

2014-05-12T22:05:57Z

Device types which are supported by both host and device can be identified when EXT_CSD is read. There is no need to check host's capability anymore. Signed-off-by: Seungwon Jeon Tested-by: Jaehoon Chung Acked-by: Jaehoon Chung Signed-off-by: Ulf Hansson Signed-off-by: Chris Ball
