This patch adds a new MFD driver for the RDC321x southbridge. This southbridge is always present in the RDC321x System-on-a-Chip and provides access to some GPIOs as well as a watchdog. Access to these two functions is done using the southbridge PCI device configuration space. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
