[PATCH v3 2/4] mfd: add Gateworks System Controller core driver

2018-03-28 Thread Tim Harvey
The Gateworks System Controller (GSC) is an I2C slave controller implemented with an MSP430 micro-controller whose firmware embeds the following features: - I/O expander (16 GPIO's) using PCA955x protocol - Real Time Clock using DS1672 protocol - User EEPROM using AT24 protocol - HWMON using cu
