Subject: [PATCH V4 0/2] imx8m: add mu support

From: Peng Fan <[email protected]>

V4:
Drop patch 1/3, since https://lkml.org/lkml/2020/6/1/370 already
has the yaml changes

V3:
Add R-b tag
Remove undocumented property

V2:
Add dt-bindings
Merge dts changes into one patch, since all is to add mu node

Add mu dt bindings
Add mu node
Add i.MX8MP mu root clk
