Hi, While adding upstream support to a new platform (Mobileye EyeQ5[1]) that uses the AMBA PL011 driver, I took some time to look at the PL011 driver and ended up with a few patches that cleanup parts of it. The line-diff is big mostly because of the checkpatch-fixing commits. The driver hadn't received any love for quite some time. See commit messages for more information. v6 drops [PATCH v5 1/9] as it has been applied by Greg KH. It also fixes [PATCH v5 2/9] that broke on ARCH=arm ep93xx_defconfig because the header file is included from assembly.
