* clk: convert API to match reset/mailbox styleStephen Warren2016-06-191-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* dm: rockchip: mmc: Allow use of CONFIG_BLKSimon Glass2016-05-271-0/+31

* dm: mmc: Set up the device pointer when using the MMC uclassSimon Glass2016-05-171-0/+1
| | | | | | | Update the existing drivers to set up this new pointer. This will be required by the MMC uclass. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: Use a separate clock ID for clocksSimon Glass2016-01-211-8/+5
| | | | | | | | | | At present we use the same peripheral ID for clocks and pinctrl. While this works it is probably better to use the device tree clock binding ID for clocks. We can use the clk_get_by_index() function to find this. Update the clock drivers and the code that uses them. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: mmc: Use a pwrseq device if availableSimon Glass2016-01-211-0/+47
| | | | | | | Use the pwrseq uclass to find a suitable power sequence for the MMC device. If this is enabled in the device tree, we will pick it up automatically. Signed-off-by: Simon Glass <sjg@chromium.org>
* mmc: rockchip: the non-removable property must point to emmchuang lin2016-01-151-0/+2
| | | | | | | | | the non-removable property point to sdcard before, it is wrong, it must point to emmc, correct it. Signed-off-by: Lin Huang <hl@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
* rockchip: mmc: get the fifo mode and fifo depth property from dtshuang lin2015-12-011-4/+17
| | | | | | | | rk3036 mmc do not have internal dma, so we use fifo mode when read and write data, we get the fifo mode and fifo depth property from dts, pass to dw_mmc driver. Signed-off-by: Lin Huang <hl@rock-chips.com>
* rockchip: mmc: use non-removable property to distinguish emmc and sdcard ↵huang lin2015-12-011-2/+3
| | | | | | | | | | register emmc and sdcard have different register address, use non-removeable property to distinguish them. Signed-off-by: Lin Huang <hl@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org>
* rockchip: Add an MMC driverSimon Glass2015-09-021-0/+98
Add an MMC driver which supports RK3288, but may also support other SoCs. It uses the Designware MMC device. Signed-off-by: Simon Glass <sjg@chromium.org>
