Subject: cpsw: rename register banks to match the reference manual, part 2
X-Git-Tag: MMI-PSA29.97-13-9~15401^2~449
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a65dd5b236053fbafb1926b7694fcdb2482b2f73;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

cpsw: rename register banks to match the reference manual, part 2

The code mixes up the CPSW_SS and the CPSW_WR register naming. This patch
changes the names to conform to the published Technical Reference Manual
from TI, in order to make working on the code less confusing.
