2015-05-14test: dm: add sandbox PMIC framework testsPrzemyslaw Marczak
This change adds new file to sandbox driver model test environment. The file is: test/dm/power.c, and it includes tests for PMIC framework, which includes PMIC uclass and REGULATOR uclass. All tests are based od Sandbox PMIC emulated device. Some test constants for this device are defined in the header: include/power/sandbox_pmic.h PMIC tests includes: - pmic get - tests, that pmic_get() returns the requested device - pmic I/O - tests I/O by writing and reading some values to PMIC's registers and then compares, that the write/read values are equal. The regulator tests includes: - Regulator get by devname/platname - Voltage set/get - Current set/get - Enable set/get - Mode set/get - Autoset - List autoset For the regulator 'get' test, the returned device pointers are compared, and their names are also compared to the requested one. Every other test, first sets the given attribute and next try to get it. The test pass, when the set/get values are equal.

2015-05-14sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulatorPrzemyslaw Marczak
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.

2015-05-14dm: regulator: add max77686 regulator driverPrzemyslaw Marczak
This commit adds support to MAX77686 regulator driver, based on a driver model regulator's API. It implements almost all regulator operations, beside those for setting and geting the Current value. For proper bind and operation it requires the MAX77686 PMIC driver.

2015-05-14dm: pmic: add max77686 pmic driverPrzemyslaw Marczak
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.

2015-05-14dm: regulator: add implementation of driver model regulator uclassPrzemyslaw Marczak
This commit introduces the implementation of dm regulator API. Device tree support allows for auto binding. And by the basic uclass operations, it allows to driving the devices in a common way. For detailed informations, please look into the header file. Core files: - drivers/power/regulator-uclass.c - provides regulator common functions api - include/power/regulator.h - define all structures required by the regulator Changes: - new uclass-id: UCLASS_REGULATOR - new config: CONFIG_DM_REGULATOR Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-05-14dm: pmic: add implementation of driver model pmic uclassPrzemyslaw Marczak
This commit introduces the PMIC uclass implementation. It allows providing the basic I/O interface for PMIC devices. For the multi-function PMIC devices, this can be used as I/O parent device, for each IC's interface. Then, each PMIC particular function can be provided by the child device's operations, and the child devices will use its parent for read/write by the common API. Core files: - 'include/power/pmic.h' - 'drivers/power/pmic/pmic-uclass.c' The old pmic framework is still kept and is independent. For more detailed informations, please look into the header file. Changes: - new uclass-id: UCLASS_PMIC - new config: CONFIG_DM_PMIC Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>
