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. v5 has been rebased upon v6.7-rc1, with [PATCH v4 3/6] split into many small commits and a header include in [PATCH v4 2/6] to fix a kernel test robot report.
