From d25cfe9b4f9663216ce4e011e3f1e7fa669ab58a Mon Sep 17 00:00:00 2001

Subject: [PATCH] reset: Add shared reset_control_[de]assert variants

Add reset_control_deassert_shared / reset_control_assert_shared
functions which are intended for use by drivers for hw blocks which
(may) share a reset line with another driver / hw block.

Unlike the regular reset_control_[de]assert functions these functions
keep track of how often deassert_shared / assert_shared have been called
and keep the line deasserted as long as deassert has been called more
times than assert.
