The patch titled mfd: add support for the RDC321x southbridge has been removed from the -mm tree. Its filename was mfd-add-support-for-the-rdc321x-southbridge.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: mfd: add support for the RDC321x southbridge From: Florian Fainelli <florian@xxxxxxxxxxx> Add 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.
