From e81c98649b7a67d43c5baae407430a242d3b26b9 Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Mon, 4 Sep 2017 14:55:56 +0200 Subject: dm: core: add clocks node scan Currently, all fixed-clock declared in "clocks" node in device tree can be binded by clk_fixed_rate.c driver only if each of them have the "simple-bus" compatible string. This constraint has been invoked here [1]. This patch offers a solution to avoid adding "simple-bus" compatible string to nodes that are not busses.
