-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>
----
-Changes from v2:
-- pass the pci_dev pointer to MFD cell drivers as platform_data
-- remove the printk(KERN_ERR and use dev_err instead
-- removed pci_dev accessors
-- use DEFINE_PCI_DEVICE_TABLE
