Subject[PATCH v8 0/3] Add support for the Gateworks System Controller
This series adds support for the Gateworks System Controller used on Gateworks
Laguna, Ventana, and Newport product families.

The GSC is an MSP430 I2C slave controller whose firmware embeds the following
- I/O expander (16 GPIO's emulating a PCA955x)
- EEPROM (enumating AT24)
- RTC (enumating DS1672)
- Interrupt controller with tamper detect, user pushbotton
- Watchdog controller capable of full board power-cycle
- Power Control capable of full board power-cycle

see for more details
- mfd: whitespace fixes
