From 13c033bc630a2df51931d16ea5fb81710ad2e0b2 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Fri, 7 Dec 2018 10:03:39 +0000 Subject: [PATCH] ARM: dts: imx7ulp: add HSRUN mode clocks i.MX7ULP can switch CPU between RUN mode and HSRUN mode by programming SMC1 register, different clock sources will be used for CPU in different modes, so SMC1 can be abstracted as a clock controller for CPU clock switch, this patch adds support for it.
