* rockchip: spi: Remove the explicit pinctrl settingSimon Glass2016-01-21-26/+2
| | | | | | | | The correct pinctrl is handled automatically so we don't need to do it in the driver. The exception is when we want to use a different chip select (other than 0). But this isn't used at present. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: spi: Correct chip-enable codeSimon Glass2016-01-21-1/+6
| | | | | | | | At present there is an incorrect call to rkspi_enable_chip(). It should be disabling the chip, not enabling it. Correct this and ensure that the chip is disabled when releasing the bus. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: spi: Implement the delaysSimon Glass2016-01-21-4/+23
| | | | | | | | Some devices need delays before and after activiation. Implement these features in the SPI driver so that we will be able to enable the Chrome OS EC. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: gpio: Implement the get_function() methodSimon Glass2016-01-21-4/+36
| | | | | | | Provide this method so that 'gpio status' works fully. It now shows whether a pin is used for input, output or some other function. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: gpio: Read the GPIO value correctlySimon Glass2016-01-21-1/+1
| | | | | | This function should return 0 or 1, not a mask. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: pinctrl: Implement the get_gpio_mux() methodSimon Glass2016-01-21-16/+52
| | | | | | | Implement this so that the GPIO command will be able to report whether a GPIO is used for input or output. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: pinctrl: Reduce the size for SPLSimon Glass2016-01-21-3/+17
| | | | | | | This file has many features that are not needed by SPL. Use #ifdef to remove the unused features and reduce the code size. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: clk: Make rkclk_get_clk() SoC-specificSimon Glass2016-01-21-0/+30
| | | | | | | | | | | | The current method assumes that clocks are numbered from 0 and we can determine a clock by its number. It is safer to use an ID in the clock's platform data to avoid the situation where another clock is bound before the one we expect. Move the existing code into rk3036 since it still works there. Add a new implementation for rk3288. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: spi: Correct the bus init codeSimon Glass2016-01-21-2/+2
| | | | | | | Two of the init values are created locally so cannot be out of range. The masking is unnecessary and in one case is incorrect. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: spi: Remember the last speed to avoid re-setting itSimon Glass2016-01-21-1/+4
| | | | | | | Rather than changing the clock to the same value on every transaction, remember the last value and don't adjust the clock unless it is necessary. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: clk: Add a simple version of clk_get_by_index()Simon Glass2016-01-21-1/+17
| | | | | | | This function adds quite a bit of code to SPL and we probably don't need all the features in SPL. Add a simple version (for SPL only) to save space. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: power: Allow regulators to not implement all operationsSimon Glass2016-01-21-0/+2
| | | | | | | | Some regulators will not implement any operations (e.g. fixed regulators). This is not an error, so allow the autoset process to continue when one of these regulators is found. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: power: Tidy up debugging output and return valuesSimon Glass2016-01-21-8/+19
| | | | | | | | The currect PMIC debugging is a little confusing. Adjust it so that it is clear whether the operation succeeded or failed. Also, avoid creating a new error return value when a perfectly good one is already available. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: core: Export uclass_find_device_by_of_offset()Simon Glass2016-01-21-2/+2
| | | | | | | | 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/+10
| | | | | | | | | | | | | 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. Signed-off-by: Simon Glass <sjg@chromium.org>
* 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. Signed-off-by: Simon Glass <sjg@chromium.org>
* 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>
* 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: spi: Update the driver to use the new clock IDSimon Glass2016-01-21-15/+17
| | | | | | We can use the new clk_get_by_index() function to get the correct clock. Signed-off-by: Simon Glass <sjg@chromium.org>

* rockchip: clock: Add a function to find a clock by IDSimon Glass2016-01-21-2/+22
| | | | | | | | 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/+48
| | | | | | | | | | 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 Glass2016-01-21-0/+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 Glass2016-01-21-2/+2
| | | | | | | | | 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>
* dm: Add a power sequencing uclassSimon Glass2016-01-21-0/+43
| | | | | | | | Some devices need special sequences to be used when starting up. Add a uclass for this. Drivers can be added to provide specific features as needed. Signed-off-by: Simon Glass <sjg@chromium.org>
* power: Add support for RK808 regulatorsSimon Glass2016-01-21-0/+311

* power: Add base support for the RK808 PMICSimon Glass2016-01-21-0/+106
| | | | | | | | | | 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: pinctrl: Add a function to parse PIN_CONFIG flagsSimon Glass2016-01-21-0/+12
| | | | | | | | 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>

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Most of the time we don't need to rotate the display so a simple font blitting feature is enough for our purposes. Add a simple driver which supports this function. It provides text output on the console using the standard 8x16-pixel font.

| | | | | | | | | | | | | | | | | | | | | | | | The existing LCD/video interface suffers from conflating the bitmap display with text output on that display. As a result the implementation is more complex than it needs to me. We can support multiple text console drivers. Create a separate uclass to support this, with its own API.

| * dm: video: Add a video uclassSimon Glass2016-01-20-0/+269
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has separate code for LCDs and 'video' devices. Both now use a very similar API thanks to earlier work by Nikita Kiryanov. With the driver- model conversion we should unify these into a single uclass. Unfortunately there are different features supported by each. This implementation provides for a common set of features which should serve most purposes. The intent is to support: - bitmap devices with 8, 16 and 32 bits per pixel - text console wih white on black or vice versa - rotated text console - bitmap display (BMP format) More can be added as additional boards are ported over to use driver model for video. The name 'video' is chosen for the uclass since it is more generic than LCD. Another option would be 'display' but that would introduce a third concept to U-Boot which seems like the wrong approach. The existing LCD and video init functions are not needed now, so this uclass makes no attempt to implement them.
