Alex Elder says:

====================
net: ipa: GSI register consolidation

This series rearranges and consolidates some GSI register
definitions.  Its general aim is to make things more
consistent, by:
  - Using enumerated types to define the values held in GSI register
    fields
  - Defining field values in "gsi_reg.h", together with the
    definition of the register (and field) that holds them
  - Format enumerated type members consistently, with hexidecimal
    numeric values, and assignments aligned on the same column

There is one checkpatch "CHECK" warning requesting a blank line; I
ignored that because my intention was to group certain definitions.
