Lunev\" via" This patch set implements the System manager bus (SMBus) module in NPCM7XX SoC. Basically, it emulates the data transactions of the module, not the SDA/SCL levels. We have also added a QTest which contains read and write operations for both single-byte and FIFO mode, and added basic I2C device trees for npcm750-evb and quanta-gsj boards. We also cleaned up the unimplemented GPIO devices in npcm7xx.c since they are already implemented.
