[PATCH UCC TDM 1/3 Updated] Platform changes for UCC TDM driver forMPC8323eRDB. Also includes related QE changes and dts entries.
From: Poonam_Aggrwal-b10812
Date: Thu Jan 24 2008 - 05:30:33 EST
Thanks Stephen for your comments, incorporated them.
From: Poonam Aggrwal <b10812@xxxxxxxxxxxxx>
This patch makes necessary changes in the QE and UCC framework to support
TDM. It also adds support to configure the BRG properly through device
tree entries. Includes the device tree changes for UCC TDM driver as well.
It also includes device tree entries for UCC TDM driver.
Tested on MPC8323ERDB platform.
