This patch looks like it should be in the 3.9-stable tree, should we apply
it?
------------------
From: "Thomas Petazzoni <thomas.petazzoni@xxxxxxxxxxxxxxxxxx>"
commit 768dc16397fb18c9de209cbcb84d890b8279faa7 upstream
The UART2 hwmod structure is pointing to the EDMA channels of UART1,
which doesn't look right. This patch fixes this by making the UART2
hwmod structure to a new structure that lists the EDMA channels to be
used by the UART2.
