* 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 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>

| | | | | | | 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
| | | | | | This saves some code space in SPL which is useful on jerry. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Add a power sequencing uclassSimon Glass2016-01-21-0/+62
| | | | | | | | 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/+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>

| | | | | | | 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>

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

| | | | | | | | | | | | | | | | | | Register video drivers with stdio so that they can be used for text output. This needs to be done explicitly for now.

| * dm: video: Implement the bmp command for driver modelSimon Glass2016-01-20-1/+375
| | | | | | | | | | | | | | | | | | This command can use the bitmap display code in the uclass. This is similar to the code in lcd.c and cfb_console.c. These other copies will go away when all boards are converted to use driver model for video. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
| * dm: common: Add memory reservation for the video uclassSimon Glass2016-01-20-12/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. No video device should be probed before relocation. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>

| | | | | | | | | | | | | | | | | | Sometimes the console must be rotated. Add a driver which supports rotating the text clockwise to 90, 180 and 270 degrees.

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

| | | | | | | | | | | | | | | | | | The LCD functions and definitions are not used with the driver model video uclass. When all boards are converted over we can remove the file. For now, use #ifdef to omit the contents. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
| * dm: video: Add a video uclassSimon Glass2016-01-20-6/+432
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
