[PATCH V3 2/2] ARM: dts: imx6sx-sabreauto: add external 24MHz clock source

From: Anson Huang
Date: Fri Apr 20 2018 - 03:42:40 EST


On i.MX6SX SabreAuto board, there is external 24MHz clock
source for analog clock2, add this clock source to clock tree
and remove "clocks" container for all input clocks.

Signed-off-by: Anson Huang <Anson.Huang@xxxxxxx>
---
changes since V2:
remove "clocks" container and use new way for all input clocks definition.
