sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulator

2015-05-15T01:58:34Z

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: pmic: code cleanup of PMIC uclass driver

2015-05-15T01:58:34Z

The cleanup includes: - pmic.h - fix mistakes in a few comments - pmic operations: value 'reg_count' - redefine as function call - fix function name: pmic_bind_childs() -> pmic_bind_children() - pmic_bind_children: change the 'while' loop with the 'for' - add implementation of pmic_reg_count() method - pmic_bind_children() - update function call name - Kconfig: add new line at the end of file - Update MAX77686 driver code Signed-off-by: Przemyslaw Marczak Acked-by: Simon Glass Tested on sandbox: Tested-by: Simon Glass

dm: pmic: add max77686 pmic driver

2015-05-15T00:49:38Z

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. Signed-off-by: Przemyslaw Marczak Acked-by: Simon Glass

dm: pmic: add implementation of driver model pmic uclass

2015-05-15T00:49:37Z

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 Acked-by: Simon Glass

pmic: add tps62362 simple wrapper code

2015-01-13T20:26:10Z

This regulator is used with AM437x IDK to feed VDD_MPU, without means to scale VDD_MPU we can't support higher frequencies. Signed-off-by: Felipe Balbi

arm: odroid: pmic77686: allow buck voltage settings

2014-11-17T10:33:21Z

Allow to set the buck voltage for the max77686. This will be used to reset the SMC LAN9730 ethernet on the odroids. Signed-off-by: Suriyan Ramasami Signed-off-by: Minkyu Kang

cros_ec: exynos: Use the correct tps65090 driver in each case

2014-10-08T08:25:47Z

Exynos 5250 boards (snow, spring) use the I2C driver but Exynos 5420 boards cannot due to a hardware design decision. Select the correct driver to use in each case. Signed-off-by: Simon Glass Tested-by: Ajay Kumar Signed-off-by: Minkyu Kang

cros_ec: power: Add a tunnelled version of the tps65090 driver

2014-10-08T08:25:46Z

Unfortunately on Pit the AP has no direct access to the tps65090 but must talk through the EC (over SPI) to the EC's I2C bus. When driver model supports PMICs this will be relatively easy. In the meantime the best approach is to duplicate the driver. It will be refactored once driver model support is expanded. Signed-off-by: Simon Glass Tested-by: Ajay Kumar Signed-off-by: Minkyu Kang

pmic: pmic_pfuze100: Use a shorter name for PMIC name

2014-08-08T08:29:41Z

It is redundant to use 'PFUZE100_PMIC' as the PMIC name because we already know it is a PMIC. Call it simply 'PFUZE100' instead. Cc: Tim Harvey Cc: Markus Niebel Signed-off-by: Fabio Estevam

tps65218/am43xx_evm: Add power framework support to TPS65218

2014-07-25T19:21:06Z

Add in an init function for the drivers/power framework so we can dump and read the registers via i2c. Cc: Łukasz Majewski Signed-off-by: Tom Rini
