[U-Boot] [PATCH 065/080] gpio: mpc8xxx: Rename Kconfig option, structures, and functions

Mario Six mario.six at gdsys.cc
Fri Sep 29 12:52:23 UTC 2017


Rename the Kconfig option, structures (and their members), as well as
functions of the mpc85xx driver to include mpc8xxx to reflect the more
generic usage.
