+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
