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 features: - I/O expander (16 GPIO's emulating a PCA955x) - EEPROM (enumating AT24) - RTC (enumating DS1672)
Hi Tim
Maybe it is in these patches, and i missed it....
How do these emulated devices work? Does the controller respond to
different addresses for these different emulated devices? Or is it an
I2c bus mux?
