2016-01-21rockchip: Convert the PMU IOMUX registers into an arraySimon Glass
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>

2016-01-21dm: Add a power sequencing uclassSimon Glass
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>

2016-01-21power: Add base support for the RK808 PMICSimon Glass

2016-01-21dm: pinctrl: Add a function to parse PIN_CONFIG flagsSimon Glass
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>
2016-01-21dm: core: Don't set pinctrl for pinctrl devicesSimon Glass
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>

2016-01-21dm: clk: Add support for decoding clocks from the device treeSimon Glass
Add a method which can locate a clock for a device, given its index.

2016-01-21clk: add fixed rate clock driverMasahiro Yamada
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.

2016-01-20dm: stdio: video: Plumb the video uclass into stdioSimon Glass
Register video drivers with stdio so that they can be used for text output. This needs to be done explicitly for now. At some point we should be able to convert stdio itself to driver model and avoid this step. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Implement the bmp command for driver modelSimon Glass
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>
2016-01-20dm: common: Add memory reservation for the video uclassSimon Glass
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.

2016-01-20dm: video: Add a driver for a rotated text consoleSimon Glass
Sometimes the console must be rotated. Add a driver which supports rotating the text clockwise to 90, 180 and 270 degrees. This can support devices where the display is rotated for mechanical reasons. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Add a 'normal' text console driverSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Add a uclass for the text consoleSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: lcd: Avoid using the lcd.h header file with driver modelSimon Glass
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>
2016-01-20dm: video: Add a video uclassSimon Glass
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.

Some tests in command_ut.c can only be executed from C code, since they test internal (more unit-level) features of various U-Boot APIs.
