2015-07-21dm: pmic: Add functions to adjust PMIC registersSimon Glass
It is a common requirement to update some PMIC registers. Provide some simple convenience functions to do this. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
2015-07-21dm: power: Use debug() for errors in regulator uclassSimon Glass
To reduce unnecessary code size in an uncommon code path, use debug() where possible(). The driver returns an error which indicates failure. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
2015-07-21dm: power: Add a function to set up all regulatorsSimon Glass
The device tree provides information about which regulators should be on at boot, or always on. Use this to set them up automatically. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
2015-07-21dm: pmic: Split output from functionSimon Glass
The regulator_autoset() function mixes printf() output and PMIC adjustment code. It provides a boolean to control the output. It is better to avoid missing logic and output, and this permits a smaller SPL code size. So split the output into a separate function. Also rename the function to have a by_name() suffix, since we would like to be able to pass a device when we know it, and thus avoid the name search.

2015-07-21dm: power: Add regulator flags to centralise auto-set logicSimon Glass
Decide when the regulator is set up whether we want to auto-set the voltage or current. This avoids the complex logic spilling into the processing code.

2015-07-21dm: power: Avoid case-insensitve match for child namesSimon Glass
This is not user input (i.e. from the command line). It should be possible to get the case correct and avoid the case-insensitive match. This will help avoid sloppy device tree setups.

Allow read errors to be diagnosed more easily. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: mmc: Add an MMC uclassSimon Glass
Add basic support for MMC, providing a uclass which can set up an MMC device. This allows MMC drivers to move to using driver model. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: led: Add a driver for GPIO-controlled LEDsSimon Glass
Add a simple driver which allows use of LEDs attached to GPIOs. The linux device tree binding is used. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: Add support for LEDsSimon Glass
Add a simple uclass for LEDs, so that these can be controlled by the device tree and activated when needed. LEDs are referred to by their label. This implementation requires a driver for each type of LED (e.g GPIO, I2C). Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: Add support for generic system controllers (syscon)Simon Glass
Many SoCs have a number of system controllers which are dealt with as a group by a single driver. It is a pain to have to add lots of compatible strings and/or separate drivers for each. Instead we can identify the controllers by a number and request the address of the one we want. Add a simple implementation of this which can be used by SoC driver code. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: Add support for register maps (regmap)Simon Glass
Add a simple implementaton of register maps, supporting only direct I/O for now. This can be enhanced later to support buses which have registers, such as I2C, SPI and PCI. It allows drivers which can operate with multiple buses to avoid dealing with the particulars of register access on that bus. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: gpio: Add dm_gpio_request() to manually request a GPIOSimon Glass
This function can be used for testing to manually request a GPIO for use, without resorting to the legacy GPIO API. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: gpio: Add dm_gpio_lookup_name() to look up a GPIO nameSimon Glass

2015-07-21dm: core: Correct device_get_child_by_of_offset() parameterSimon Glass
This parameter is named 'seq' but should be named 'of_offset'. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: core: Add a function to find any device from device treeSimon Glass
In some rare cases it is useful to be able to locate a device given a device tree node offset. An example is when you have an alias that points to a node and you want to find the associated device. The device may be SPI, MMC or something else, but you don't need to know the uclass to find it. Add a function to do a global search for a device, given its device tree offset. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: core: Use debug() instead of printf() for failuresSimon Glass
To avoid bloating SPL code, use debug() where possible in the driver model core code. The error code is already returned, and can be investigated as needed. Signed-off-by: Simon Glass <sjg@chromium.org>
2015-07-21dm: Move the tree/uclass dump code into its own fileSimon Glass
In SPL it is sometimes useful to be able to obtain a dump of the current driver model state. Since commands are not available, provide a way to directly call the functions to output this information. Adjust the existing commands to use these functions. Signed-off-by: Simon Glass <sjg@chromium.org>

2015-07-14pci: Configure expansion ROM during auto config processBin Meng
Currently PCI expansion ROM address is assigned by a call to pciauto_setup_rom() outside of the pci auto config process. This does not work when expansion ROM is on a device behind PCI bridge where bridge's memory limit register was already programmed to a value that does not cover the newly assigned expansion ROM address. To fix this, we should configure the ROM address during the auto config process.
