* dm: led: Add a driver for GPIO-controlled LEDsSimon Glass2015-07-21-0/+52
| | | | | | | 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>
* dm: Add support for LEDsSimon Glass2015-07-21-0/+23
| | | | | | | | | 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>

| * fdt: Pass the device serial number through devicetreePaul Kocialkowski2015-06-05-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before device-tree, the device serial number used to be passed to the kernel using ATAGs (on ARM). This is now deprecated and all the handover to the kernel should now be done using device-tree. Thus, this passes the serial-number property to the kernel using the serial-number property of the root node, as expected by the kernel. The serial number is a string that somewhat represents the device's serial number. It might come from some form of storage (e.g. an eeprom) and be programmed at factory-time by the manufacturer or come from identification bits available in e.g. the SoC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds emulation of sandbox PMIC device, which includes: - PMIC I2C emulation driver - PMIC I/O driver (UCLASS_PMIC) - PMIC regulator driver (UCLASS_REGULATOR) The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes, which allows using 'i2c md' command with the default count (16). The sandbox PMIC provides regulators: - 2x BUCK - 2x LDO Each, with adjustable output: - Enable state - Voltage - Current limit (LDO1/BUCK1 only) - Operation mode (different for BUCK and LDO) Each attribute has it's own register, beside the enable state, which depends on operation mode. The header file: sandbox_pmic.h includes PMIC's default register values, which are set on i2c pmic emul driver's probe() method.

* dm: regulator: add fixed voltage regulator driverPrzemyslaw Marczak2015-05-14-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | This driver implements regulator operations for fixed Voltage/Current value regulators. beside the standard regulator constraints, which are put into the uclass platform data, a typical fixed regulator node provides few additional properties like: - gpio - gpio-open-drain - enable-active-high - startup-delay-us The only 'gpio' is used by this driver and is kept in structure of type 'fixed_regulator_platdata', as a device platform data (dev->platdata). The driver implements: - get_value - get_current - get_enable - set_enable The regulator calls and commands can be used for fixed-regulator devices, and the proper error will be returned for prohibited.

| | | | | | | | | | | | | | | This is the implementation of driver model PMIC driver. The max77686 PMIC driver implements read/write operations and driver bind method - to bind its childs. This driver will try to bind the regulator devices by using it's child info array with regulator prefixes and driver names. This should succeed when compatible regulator driver is compiled. If no regulator driver found, then the pmic can still provide read/write operations, and can be used with PMIC function calls.

This will be immediately used by the Raspberry Pi board in U-Boot, and likely will be used by the Samsung ARM ChromeBook support soon too.
