Subject: imx: Generalize fixup_thermal_trips
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=d0fe80890ab1bee431ffaed5e75f35dfb5054b7b;p=u-boot.git

imx: Generalize fixup_thermal_trips

i.MX8M and i.MX9 have duplicated fixup_thermal_trips, so move it
to arch/arm/mach-imx/fdt.c to avoid duplicated code.

The critial temperature point for i.MX9 set to "maxc - 5" back to give
some margin.
