From 2457612d6d374bd67d3317f11cf24fc0bba02274 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 31 Jul 2019 07:01:23 +0000 Subject: clk: introduce clk_dev_binded When support Clock Common Framework, U-Boot use dev for clk tree information, there is no clk->parent. When support composite clk, it contains mux/gate/divider, but the mux/gate/divider is not binded with device. So we could not use dev_get_uclass_priv to get the correct clk_mux/gate/divider. So add clk_dev_binded to let choose the correct method.
