[PATCH v3 6/6] arm64: dts: qcom: hamoa: add thermal hw-bin support
From: Gaurav Kohli
Date: Fri Nov 13 2026 - 07:45:17 EST
From: Amit Kucheria <amit.kucheria@xxxxxxxxxxxxxxxx>
hamoa-based SoCs expose their manufacturing bin in a single i-temp bit
of a qfprom fuse. Add the i-temp nvmem cell to the qfprom node
and wire the tsens controllers to it so the tsens driver can feed
the bin to the thermal core.
Use that bin for the GPU passive trip points so industrial-temp
parts keep the higher 105C threshold without a board-specific
override.
