Commit Message

Linus Walleij May 20, 2017, 9:42 p.m. UTC
This switches the arbitrary shifting of hex constants in
the pl080 header to use GENMASK().

Suggested-by: Vinod Koul <vinod.koul@intel.com>
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ChangeLog v1->v2:
- New patch at the end of the series in response to
  Vinods request to use GENMASK().
