This is a note to let you know that I have just added a patch titled ARC: [nsimosci] Change .dts to use generic 8250 UART to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From c12ce075a98bdd77a58e966e42d079b49e7b068d Mon Sep 17 00:00:00 2001 From: Mischa Jonker <mjonker@synopsys.com> Date: Thu, 16 May 2013 19:36:08 +0200 Subject: ARC: [nsimosci] Change .dts to use generic 8250 UART commit 6eda477b3c54b8236868c8784e5e042ff14244f0 upstream. The Synopsys APB DW UART has a couple of special features that are not in the System C model. In 3.8, the 8250_dw driver didn't really use these features, but from 3.9 onwards, the 8250_dw driver has become incompatible with our model.
