* dm: mmc: sandbox: Add an SD-card emulationSimon Glass2016-05-172-2/+143
| | | | | | | | Add an emulation of an SD card to sandbox, allowing MMC to be used in tests. The emulation is very simple, supporting only card detection and reading test data. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: mmc: Add support for driver-model block devicesSimon Glass2016-05-173-12/+54
| | | | | | | Add support for enabling CONFIG_BLK with MMC. This involves changing a few functions to use struct udevice and adding a MMC block device driver. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: mmc: Add a way to bind MMC devices with driver modelSimon Glass2016-05-171-0/+48
| | | | | | | | | | Binding an MMC device when CONFIG_BLK is enabled requires that a block device be bound as a child of the MMC device. Add a function to do this. The mmc_create() method will be used only when DM_BLK is disabled. Add an unbind method also. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: mmc: Implement the MMC functions for block devicesSimon Glass2016-05-172-1/+109
| | | | | | | | 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>
* dm: sandbox: Only enable the sandbox MMC driver when validSimon Glass2016-05-171-0/+4
| | | | | | | This driver will require generic MMC and block-device support in a future commit. To avoid test errors, make this change now. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: mmc: Adjust mmc_switch_part() to use a struct mmcSimon Glass2016-05-171-8/+4
| | | | | | | Instead of looking up the MMC device by number, just pass it in. This makes it possible to use this function with driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: mmc: Move the device list into a separate fileSimon Glass2016-05-175-117/+172
| | | | | | | | | At present the MMC subsystem maintains its own list of MMC devices. This cannot work with driver model, which needs to maintain this itself. Move the list code into a separate 'legacy' file. The core MMC code remains, and will be shared with the driver-model implementation. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: mmc: Set up the device pointer when using the MMC uclassSimon Glass2016-05-176-1/+11

* dm: mmc: Add a function to obtain the block deviceSimon Glass2016-05-171-0/+5
| | | | | | | | The MMC block device is contained within struct mmc. But with driver model this will not be the case. Add a function to obtain the block device. We can later implement this for CONFIG_BLK. Signed-off-by: Simon Glass <sjg@chromium.org>

* drivers: mmc: omap_hsmmc: Fix conversion of address to a pointerMugunthan V N2016-04-181-1/+2
| | | | | | | | | | | | | | | | | omap_hsmmc driver directly typecasts fdt_addr_t to a pointer. This is not strictly correct, as it gives a build warning when fdt_addr_t is u64. So, use map_physmem for a proper typecasts. This is inspired by commit 167efe01bc5a9 ("dm: ns16550: Use an address instead of a pointer for the uart base") drivers/mmc/omap_hsmmc.c: In function ‘omap_hsmmc_ofdata_to_platdata’: drivers/mmc/omap_hsmmc.c:776:20: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] priv->base_addr = (struct hsmmc *)dev_get_addr(dev); ^ Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support Driver Model for fsl esdhc driver. 1. Introduce a new structure struct fsl_esdhc_priv 2. Refactor fsl_esdhc_initialize which is originally used by board code. - Introduce fsl_esdhc_init to be common usage for DM and non-DM - Introduce fsl_esdhc_cfg_to_priv to build the bridge for non-DM part. - The original API for board code is still there, but we use 'fsl_esdhc_cfg_to_priv' and 'fsl_esdhc_init' to serve it. 3. All the functions are changed to use 'struct fsl_esdhc_priv', except fsl_esdhc_initialize. 4. Since clk driver is not implemented, use mxc_get_clock to geth the clk and fill 'priv->sdhc_clk'.

* dwmmc: Increase retry timeoutAlexander Graf2016-03-151-1/+1
| | | | | | | | | | | | | | When enable dcache on HiKey, we're running into MMC command timeouts because our retry loop is now faster than the eMMC (or an external SD card) can answer. Increase the retry count to the same as the timeout value for status reports. The real fix is obviously to not base this whole thing on a cycle counter but on real wall time, but that would be slightly more intrusive. Signed-off-by: Alexander Graf <agraf@suse.de>
