Subject[PATCH v3 2/2] Add support for CPCAP regulators on Motorola Xoom devices.
Date
Added support for the CPCAP power management regulator functions on
Tegra based Motorola Xoom devices.
Added sw2_sw4 value tables, which provide power to the Tegra core and
aux devices.
Added the Xoom init tables and device tree compatibility match.
