2017-06-09dm: mmc: Avoid probing block devices in find_mmc_device()Simon Glass
We do not need to probe the block device here, so avoid doing so. The MMC device itself must be active, but the block device can come later. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: mmc: Convert uclass to livetreeSimon Glass
Update the mmc uclass to support a live device tree. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: mmc: Rewrite mmc_blk_probe()Simon Glass
This function is called when the MMC block device is being probed. There is a recursive call in this function since find_mmc_device() itself can cause the MMC device to be probed. Admittedly the MMC device should already be probed, since we would not be probing its child otherwise, but the current code is unnecessarily convoluted. Rewrite this to access the MMC structure directly. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: mmc: Check that drivers have operationsSimon Glass
When binding a new MMC device, make sure that it has the required operations. Since for now we still support *not* having the operations (with CONFIG_DM_MMC_OPS not enabled) it makes sense to add this check. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-06-01dm: core: Replace of_offset with accessor (part 2)Simon Glass
At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

2017-04-04dm: core: Add flags parameter to device_remove()Stefan Roese
This patch adds the flags parameter to device_remove() and changes all calls to this function to provide the default value of DM_REMOVE_NORMAL for "normal" device removal. This is in preparation for the driver specific pre-OS (e.g. DMA cancelling) remove support.

2017-02-09mmc: init mmc block devices on probeFiach Antaw
MMC devices accessed exclusively via the driver model were not being initialized before being exposed as block devices, causing issues in scenarios where the MMC device is first accessed via the uclass block interface. Signed-off-by: Fiach Antaw <fiach.antaw@uqconnect.edu.au>
2017-02-09mmc: mmc-uclass: use the fixed devnum with alias nodeJaehoon Chung
If there are alias nodes as "mmc", use the devnum as alias index number. This patch is for fixing a problem of Exynos4 series. Problem is the below thing. Current legacy mode: EXYNOS DWMMC: 0, SAMSUNG SDHCI: 1 After using DM: SAMSUNG SDHCI: 0, EXYNOS DWMMC: 1 Dev index is swapped. Then u-boot can't find the kernel image..because it is already set to 0 as mmcdev. If change from legacy to DM, also needs to touch all exynos4 config file. For using simply, just supporting the fixed devnum with alias node is better than it. Usage: alaise { .... mmc0 = &sdhci2; /* eMMC */ mmc1 = &sdhci1; /* SD */ ... } Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2016-10-09dm: mmc: Support eraseSimon Glass
At present erase is not suported with CONFIG_DM_OPS. Add it so that MMC devices can be erased. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-08-05mmc: display mmc list information like mmc_legacy typeXu Ziyuan
It's nicer to see this: => mmc list dwmmc@ff0c0000: 0 dwmmc@ff0f0000: 1 (eMMC) than this: => mmc list dwmmc@ff0c0000: 0dwmmc@ff0f0000: 1 (eMMC) With the former, it's much clearer which mmc devices are on.

2016-07-31mmc-uclass: correct the device numberKever Yang
Not like the mmc-legacy which the devnum starts from 1, it starts from 0 in mmc-uclass, so the device number should be (devnum + 1) in get_mmc_num(). Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>
2016-07-11dm: mmc: Add a way to use driver model for MMC operationsSimon Glass
The driver model conversion for MMC has moved in small steps. The first step was to have an MMC device (CONFIG_DM_MMC). The second was to use a child block device (CONFIG_BLK). The final one is to use driver model for MMC operations (CONFIG_DM_MMC_OP). Add support for this. The immediate priority is to make all boards that use DM_MMC also use those other two options. This will allow them to be removed. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-07-11dm: mmc: Move CONFIG_BLK code into the mmc uclassSimon Glass
Rather than having #ifdef in mmc.c, move this code into the uclass file. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-05-17dm: mmc: Implement the MMC functions for block devicesSimon Glass
Implement the functions in mmc_legacy.c for driver-model block devices, so that MMC can use driver model for these. This allows CONFIG_BLK to be enabled with DM_MMC. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: mmc: Add an MMC uclassSimon Glass
Add basic support for MMC, providing a uclass which can set up an MMC device. This allows MMC drivers to move to using driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
