[U-Boot] [PATCH v3 0/6] power: pmic: Add support for Palmas family of PMICs

[U-Boot] [PATCH v3 0/6] power: pmic: Add support for Palmas family of PMICs

[Keerthy]

The series adds support for Palmas family of PMICs.
Implements functions to configure regulators. Enable/Disable
Get/Set voltages of regulators.

Supports TPS659038, TPS65917, Palmas.

Tested on TPS659038, TPS65917 using DRA7XX-EVM and AM57XX-EVM. 

Changes in v3:

Introduced u8 i2c read/write functions.

Keerthy (6):
  dm: i2c: Add u8 read/write i2c functions
  power: regulator: Add ctrl_reg and volt_reg fields for      pmic
  power: pmic: Palmas: Add the base pmic support
  power: regulator: palmas: Add regulator support
  configs: am57xx_evm_defconfig: Enable PALMAS options
  configs: dra7xx_evm_defconfig: Enable PALMAS options

These look almost the same as dm_i2c_reg_read/write(), but IMO those
are easier to use since they don't require a pointer to be passed. How
do you intend to use these two new functions?

Simon,

I see a kind of issue in the current implementation of
int dm_i2c_reg_read(struct udevice *dev, uint offset)
int dm_i2c_reg_write(struct udevice *dev, uint offset, uint value)

In the current set up my need is to read and then write a 1 byte I2C 
register. It is best to have consistency with read and write.
In the current case(dm_i2c_reg_read/write) i read an integer and now 
when i want to write i need to convert it to an unsigned integer.

Instead of all this i made a patch which keeps u8 across read and write:

int dm_i2c_reg_read(struct udevice *dev, uint offset, u8 *val)
returns error/success with the return value and value is passed by 
reference in val variable.

int dm_i2c_reg_write(struct udevice *dev, uint offset, u8 *val)
returns error/success using the return value and the value to be written 
is sent in val.

Regards,
Keerthy

Well I really don't see why you can use the other functions. But if
you prefer these, then OK.

[U-Boot] [PATCH v3 2/6] power: regulator: Add ctrl_reg and volt_reg fields for pmic

[Keerthy]

The ctrl reg contains bit fields to enable and disable regulators,
and volt_reg has the bit fields to configure the voltage values.
The registers are frequently accessed hence make them part
of dm_regulator_uclass_platdata structure.
