From: Peng Fan Date: Thu, 19 Sep 2024 04:01:34 +0000 (+0800) Subject: imx: Generalize fixup_thermal_trips X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?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.
