From 3567894b6914813299300019e028874927210880 Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Wed, 31 Jul 2019 10:40:16 +0200 Subject: clk: core: introduce clk_hw_set_parent() Introduce the clk_hw_set_parent() provider call to change parent of a clock by using the clk_hw pointers. This eases the clock reparenting from clock rate notifiers and implementing DVFS with simpler code avoiding the boilerplates functions as __clk_lookup(clk_hw_get_name()) then clk_set_parent().
