Subject: thermal: imx_tmu: support TMU arch level initialization
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=84897408c688e3d3962e8cd7e92f3ad99c17005d;p=u-boot.git

thermal: imx_tmu: support TMU arch level initialization

i.MX8MM TMU needs to load some registers from fuse, this is arch
dependent operation and may vary on different platforms. So add
a interface for arch level initialization.
