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

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 also adds the I2C slave address of TPS65910 pmic to
am335x-evm.dts file.
