* mmc: dw_mmc: move rockchip related code to a separate fileaddy ke2014-09-091-57/+0Star
| | | | | | | | | | | | To support HS200 and UHS-1, we need add a big hunk of code, as shown in the following patches. So a separate file for rockchip SOCs is suitable.

* mmc: dw_mmc-pltfm: Remove superflous #else condition on CONFIG_PM_SLEEPPeter Griffin2014-09-091-3/+0Star
| | | | | | | | | As the code is using SIMPLE_DEV_PM_OPS helper, this compiles away to nothing if CONFIG_PM_SLEEP is disabled. Thus we don't need to #define the suspend/resume callbacks to NULL.

* mmc: dw_mmc: add support for RK3288Addy Ke2014-09-091-2/+54
| | | | | | | | | | | | This patch focuses on clock setting for RK3288 mmc controller. In RK3288 mmc controller, CLKDIV register can only be set 0 or 1, and if DDR 8bit mode, CLKDIV register must be set 1.

* mmc: dw_mmc: Add support for SOCFPGA's platform specific implementationDinh Nguyen2014-02-271-2/+8
| | | | | | | | | | | | | Like the rockchip, Altera's SOCFPGA platform specific implementation of the dw_mmc driver requires using the HOLD register for SD commands. This patch renames dw_mci_rockchip_prepare_command to dw_mci_pltfm_prepare_command so that SOCFPGA and Rockchip can use it.

* mmc: dw_mmc-pltfm: add Rockchip variantHeiko Stübner2013-07-051-1/+20
| | | | | | | | | | | | | | Cortex-A9 SoCs from Rockchip use a slightly modified variant of dw_mmc controllers that seems to require the SDMMC_CMD_USE_HOLD_REG bit to always be set. There also seem to be no other modifications (additional register etc) present, so to keep the footprint low, add this small variant to the pltfm driver.

The merges should all be trivial, and Stephen has been doing them all in linux-next for a few weeks now quite easily. Other than the __dev* marking removals, there's nothing major here, some firmware loading updates and other minor things in the driver core.

| | | | | | | | | | | | | | | | | | | | | Platform implementations of dw-mshc controller may choose to extend the features of the standard dw-mshc controller such as adding additional clocking options or modifying the bus interface. Support for such implementation specific extensions can be incorporated into dw_mmc-pltfm, but including multiple such platform specific implementations would convolute the existing dw_mmc-pltfm code. Instead, it would be better to create implementation specific platform drivers to support implementation specific features. Such platforms drivers can reuse the existing infrastructure in dw_mmc-pltfm for resource identification and controller registration and provide support for implementation specific features. So, allow the infrastructure in dw_mmc-pltfm to be reused by other implementation specific platform drivers.
