Subject: pinctrl: sh-pfc: Add generic bias register description
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=beaa34d9080f20c9f0994071703c5d5c012afb56;p=linux.git

pinctrl: sh-pfc: Add generic bias register description

Add a generic way to describe bias registers (for pull-up/down control),
like is already done for config and drive registers.

This makes the sh-pfc core code aware of these registers, which will
ease introducing suspend/resume support later.
