Subject: [PATCH 5/6] arm64: dts: qcom: kodiak: use thermal hw-bin trips
Date: Fri, 02 Oct 2026 16:17:00 +0530 [thread overview]
Message-ID: <20261002-thermal_bin-v1-5-5a29be7e8ec5@oss.qualcomm.com> (raw)
In-Reply-To: <20261002-thermal_bin-v1-0-5a29be7e8ec5@oss.qualcomm.com>
From: Amit Kucheria <amit.kucheria@oss.qualcomm.com>
kodiak-based SoCs are binned at manufacturing time, with the bin
computed from the jtag-id and feat-id qfprom fuses. The tsens driver
now reads these and feeds the resulting bin to the thermal core, which
selects per-bin trip temperatures.
Add the jtag-id and feat-id nvmem cells to the tsens nodes and convert
the passive mitigation trip points from a fixed 95C to per-bin values
(95C for bin 0x1, 105C for bin 0x2) using the new
temperature-bin/thermal-hw-bin properties.
