X-Git-Tag: v6.6.7~4018^2~16^2~133
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4ba146dd8897353e4e18a12c7866127f85c251e7;p=platform%2Fkernel%2Flinux-starfive.git

arm64: dts: qcom: sm6125-seine: Configure additional trinket thermistors

In addition to PMIC-specific (pm6125) thermistors downstream extends
this set with the rf-pa0/rf-pa1, quiet, camera-flash and UFS/eMMC
thermistors in sm6125 (trinket) board and seine-specific DT files.  All
thermistors report sensible temperature readings in userspace.

The sensors are also added to their respective Thermal Monitor node,
with thermal zones to match where applicable: emmc-ufs and camera-flash
are not available on the TM5 block, hence cannot be configured with a
tripping point and will not have a thermal zone.
