* rockchip: mmc: Update the driver to support of-platdataSimon Glass2016-07-14-3/+26
| | | | | | | | Add support for of-platdata with rk3288. This requires decoding the of-platdata struct and setting up the device from that. Also the driver needs to be renamed to match the string that of-platdata will search for. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: mmc: Add a way to use driver model for MMC operationsSimon Glass2016-07-11-3/+93
| | | | | | | | | | | | 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>

| * mmc: fsl: introduce wp_enablePeng Fan2016-06-28-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introudce wp_enable. To check WPSPL, wp_enable needs to be set to 1 in board code. Take i.MX6UL for example, for some boards, they do not use WP singal, so they does not configure USDHC1_WP_SELECT_INPUT, and its default value is 0(GPIO1_IO02). However GPIO1_IO02 is muxed for i2c usage and SION bit set. So USDHC controller can always get wp signal and WPSPL shows write protect and blocks driver continuing. This is not what we want to see, so add wp_enable, and if set to 0, just omit the WPSPL checking and this does not effect normal working of usdhc controller. If wp-gpios is provided in dts, wp_enable is set to 1, otherwise 0.

| * fsl_esdhc: Update clock enable bits for USDHCYe Li2016-06-28-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USDHC moves the 4 clock bits CARD_CLK_SOFT_EN, IPG_PERCLK_SOFT_EN, HCLK_SOFT_EN, and IPG_CLK_SOFT_EN from sysctl register to vendorspec register. The driver uses RSTA to replace the clock gate off operation. But this is not a good solution because: 1. when using RSTA, we should wait this bit to clear by itself. This is not implemeneted in the code. 2. After RSTA is set, it is recommended that the Host Driver reset the external card and reinitialize it. So in this patch, we change to use the vendorspec registers for these bits operation.

| * mmc: fsl: reset to normal boot mode when eMMC fast bootPeng Fan2016-06-28-9/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting in eMMC fast boot, MMC host does not exit from boot mode after bootrom loading image. So the first command 'CMD0' sent in uboot will pull down the CMD line to low and cause errors. This patch cleans the MMC boot register in "mmc_init" to put the MMC host back to normal mode. Also clear DLL_CTRL delay line settings at USDHC initialization to eliminate the pre-settings from boot rom.

* clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

* | mmc: tegra: add basic Tegra186 supportStephen Warren2016-05-31-1/+31
|/ | | | | | | | | | | | | | | | | | | | | | Tegra186's MMC controller needs to be explicitly identified. Add another compatible value for it. Tegra186 will use an entirely different clock/reset control mechanism to existing chips, and will use standard clock/reset APIs rather than the existing Tegra-specific custom APIs. The driver support for that isn't ready yet, so simply disable all clock/reset usage if compiling for Tegra186. This must happen at compile time rather than run-time since the custom APIs won't even be compiled in on Tegra186. In the long term, the plan would be to convert the existing custom APIs to standard APIs and get rid of the ifdefs completely. The system's main eMMC will work without any clock/reset support, since the firmware will have already initialized the controller in order to load U-Boot. Hence the driver is useful even in this apparently crippled state. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Tom Warren <twarren@nvidia.com>
