* dm: core: Export uclass_find_device_by_of_offset()Simon Glass2016-01-21-2/+18
| | | | | | | | It is sometimes useful to be able to find a device before probing it, perhaps to set up some platform data for it. Allow finding by of_offset also. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: pinctrl: Add a way for a GPIO driver to obtain a pin functionSimon Glass2016-01-21-0/+42
| | | | | | | | | | | | | GPIO drivers want to be able to show if a pin is enabled for input, output, or is being used by another function. Some drivers can easily find this and the code is included in the driver. For some SoCs this is more complex. Conceptually this should be handled by pinctrl rather than GPIO. Most pinctrl drivers will have this feature anyway. Add a method by which a GPIO driver can obtain the pin mux value given a GPIO reference. This avoids repeating the code in two places.

* dm: power: Allow regulators to be omitted from SPLSimon Glass2016-01-21-2/+34
| | | | | | | | For some boards the pmic interface is useful but the regulator interface (which comes with it) is too large. Allow them to be separated such that SPL can decide which it needs. Signed-off-by: Simon Glass <sjg@chromium.org>
* spi: Correct device tree usage in spi_flash_decode_fdt()Simon Glass2016-01-21-6/+3
| | | | | | | | | | | This function currently searches the entire device tree for a node that it thinks is relevant. But the node is known and is passed in. Correct the code and enable it only with driver model, since only driver-model boards will use it. This avoids bringing in a large number of strings from fdtdec.

* dm: i2c: Allow muxes to be enabled for SPL separatelySimon Glass2016-01-21-3/+12
| | | | | | | Since I2C muxes are seldom needed in SPL, and the code for this increases the size somewhat, add a separate option to enable I2C muxes for SPL. Signed-off-by: Simon Glass <sjg@chromium.org>
* cros_ec: Disable the Chrome OS EC in SPLSimon Glass2016-01-21-0/+2
| | | | | | | This is not used in SPL so don't allow it to be built there, even if I2C is enabled in SPL. Signed-off-by: Simon Glass <sjg@chromium.org>
* gpio: Allow 's' as an abbreviation for 'status'Simon Glass2016-01-21-1/+1
| | | | | | | The 'gpio' command allows abbreviations for most subcommands. Allow them for 'status' also. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: jerry: Drop unused optionsSimon Glass2016-01-21-5/+2
| | | | | | | To reduce the SPL image size, drop the LED features. Jerry does not have an LED and we can leave out GPIO support also. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: Disable simple-bus in SPL for firefly-rk3288, jerrySimon Glass2016-01-21-0/+2
| | | | | | This is not needed for booting, so drop it from SPL to save about 300 bytes. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: jerry: Enable the RK808 PMIC and regulatorSimon Glass2016-01-21-0/+2

* rockchip: pinctrl: Add a full pinctrl driverSimon Glass2016-01-21-1/+229
| | | | | | | We can make use of the device tree to configure pinctrl settings. Add this support for the driver so we can use it in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: mmc: Update the driver to use the new clock IDSimon Glass2016-01-21-1/+1
| | | | | | We can use the new clk_get_by_index() function to get the correct clock. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: spi: Avoid setting the pinctrl twiceSimon Glass2016-01-21-3/+6
| | | | | | | | If full pinctrl is enabled we don't need to manually set the pinctrl in the driver. It will happen automatically. Adjust the code to suit - we will still use manual mode in SPL. Signed-off-by: Simon Glass <sjg@chromium.org>

* rockchip: clock: Add a function to find a clock by IDSimon Glass2016-01-21-2/+34
| | | | | | | | The current approach of using uclass_get_device() is error-prone. Another clock (for example a fixed-clock) may cause it to break. Add a function that does a proper search. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: clk: Add a function to get a peripheral clock rateSimon Glass2016-01-21-0/+37
| | | | | | | It is useful to be able to read the rate of a peripheral clock. Add a handler for that. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: clock: Rename the general clock variable to gclk_rateSimon Glass2016-01-21-12/+12
| | | | | | The current name is confusing and a bit verbose. Rename it. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: Use a separate clock ID for clocksSimon Glass2016-01-21-44/+50
| | | | | | | | | | 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: jerry: Disable pmic-int-1 setup to avoid a hangSimon Glass2016-01-21-1/+4
| | | | | | | This hangs when activated (by probing the PMIC). Disable it for now until we understand the root cause. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: Use pwrseq for MMC start-up on jerrySimon Glass2016-01-21-4/+13
| | | | | | | This is defined in the device tree in Linux. Copy over the settings so that this can be used instead of hard-coding the reset line. Signed-off-by: Simon Glass <sjg@chromium.org>

* rockchip: mmc: Use a pwrseq device if availableSimon Glass2016-01-21-0/+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>
* rockchip: Convert the PMU IOMUX registers into an arraySimon Glass2016-01-21-6/+10
| | | | | | | | | This is easier to deal with when using generic code since it allows us to use a register index instead of naming each register. Adjust it, adding an enum to improve readability. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: Avoid using MMC code when not booting from MMCSimon Glass2016-01-21-0/+2

* power: Add base support for the RK808 PMICSimon Glass2016-01-21-0/+183
| | | | | | | | | | This Rockchip PMIC provides features suitable for battery-powered applications. It is commonly used with Rockchip SoCs. Add a driver which provides register access. The regulator driver will use this. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: pmic: Add 'reg status' to show all regulatorsSimon Glass2016-01-21-10/+56
| | | | | | | It is convenient to be able to see the status of all regulators in a list. Add this feature to the 'reg status' command. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: pinctrl: Add a function to parse PIN_CONFIG flagsSimon Glass2016-01-21-0/+25
| | | | | | | | Add a function which produces a flags word from a few common PIN_CONFIG settings. This is useful for simple pinctrl drivers that don't need to worry about drive strength, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Don't set pinctrl for pinctrl devicesSimon Glass2016-01-21-2/+4
| | | | | | | | | | | | | | There is sort-of race condition when a pinctrl device is probed. The pinctrl function is called which may end up using the same device as is being probed. This results in operations being used before the device is actually probed. For now, disallow pinctrl operations on pinctrl devices while probing. An alternative solution would be to move the operation to later in the device_probe() function (for pinctrl devices only) but this needs more thought. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: clk: Add support for decoding clocks from the device treeSimon Glass2016-01-21-0/+52
| | | | | | | | | Add a method which can locate a clock for a device, given its index. This uses the normal device tree bindings to return the clock device and the first argument which is normally used as a peripheral ID in U-Boot.

| | | | | | | | | | | | This commit intends to implement "fixed-clock" as in Linux. (drivers/clk/clk-fixed-rate.c in Linux) If you need a very simple clock to just provide fixed clock rate like a crystal oscillator, you do not have to write a new driver. This driver can support it.

| | | | | | | | | | | | | | | | | | | | | | | | | | Before relocation we need to reserve memory for the video driver frame buffers so that they can use this memory when they start up (after relocation). Add a call to the uclass to permit this. The current top and bottom of the region is stored in global_data so that it can be checked post-relocation to ensure enough memory is available.
