[PATCH V5 08/11] soc: mediatek: PMIC wrap: remove pwrap_is_mt8135() and pwrap_is_mt8173()

From: John Crispin
Date: Sun Feb 07 2016 - 05:45:07 EST


With more SoCs being added the list of helper functions like these would
grow. While at it also add a new flag "has_bridge" and use that instead of
pwrap_is_mt8173() where appropriate.

Changed in V4
* fix 2 typos in the description
* used a bitfiled for the new has_bridge flag
