[PATCH v2 0/3] Add device tree support for AM33XX regulators

[PATCH v2 0/3] Add device tree support for AM33XX regulators

[AnilKumar Ch]

Add device tree support for regulators present on AM33XX family
of devices like AM335X-EVM and AM335X-Bone. TPS65217 regulator
is present on AM335X-Bone and TPS65910 on AM335X-EVM.

First patch adds the device tree support to tps65217 regulator
so that it will take the parameters from tps65217.dtsi file and
convert to tps65217 regulator parameters.

Second patch adds tps65910 device tree data by adding separate
DT tps65910.dtsi file, which contains the generic tps65910 PMIC
DT data.

Third patch adds tps65217 device tree data by adding separate
tps65910.dtsi file, which contains the generic tps65910 PMIC
DT data.

This patch series was tested by adding the I2C slave address to
corresponding .dts files.

Changes form V1:
        - Add regulator-compatible data to dt files.
        - Separated device tree data addition to am335x-evm/bone dts
          from the regulator patches

[PATCH v2 1/3] regulator: tps65217: Add device tree support

[AnilKumar Ch]

This commit adds device tree support for tps65217 pmic. And usage
details are added to device tree documentation. Driver is tested
by using kernel module with regulator set and get APIs.

[PATCH v2 2/3] ARM: OMAP2+: AM33XX: Add tps65910 device tree data

[AnilKumar Ch]

Add device tree data for tps65910 regulator by adding all the
consumers necessary for AM335X-EVM. The data will be map to a
regulator constraints which is required for regulator set_voltage
and get_voltage calls.

All tps65910 PMIC regulator constraints are placed in a seperate
device tree include file (tps65910.dtsi).

This patch is tested by adding the I2C slave address of TPS65910
pmic to am335x-evm.dts file (Not included in this, I2C slave
addition patch will be submitted to linux-omap, where am335x-evm.dts
binding file is available).
