surendra	68b78ad1e3	thermal/drivers/spacemit: Validate clamped trip thresholds ... k1_tsensor_set_trips() checks the requested trip temperatures before converting them to the sensor register representation. Distinct out-of-range temperatures can clamp to the same hardware value, leaving the sensor with an invalid low/high threshold pair. Validate the ordering after conversion and clamping.

Pei Xiao	9cbf780428	thermal/drivers/spacemit/k1: Add shutdown action and reorder registration order ... Add a devm action to clean hardware interrupts, sampling, and control registers on driver unbind, mirroring what k1_tsensor_init() sets up. Reorder the registration order within probe(): register the thermal zones first, then request the IRQ, and register the shutdown action last. On removal, the hardware interrupt is disabled first, then the IRQ is released, and finally the thermal zones are released. This avoids the IRQ thread accessing an already unregistered thermal zone during devres cleanup.

Shuwei Wu	296a977f2b	thermal/drivers/spacemit/k1: Add thermal sensor support ... The thermal sensor on K1 supports monitoring five temperature zones. The driver registers these sensors with the thermal framework and supports standard operations: - Reading temperature (millidegree Celsius) - Setting high/low thresholds for interrupts Signed-off-by: Shuwei Wu <shuwei.wu@mailbox.org> Signed-off-by: Daniel Lezcano <daniel.lezcano@kernel.org> Reviewed-by: Anand Moon <linux.amoon@gmail.com> Reviewed-by: Troy Mitchell <troy.mitchell@linux.spacemit.com> Reviewed-by: Yao Zi <me@ziyao.cc> Tested-by: Anand Moon <linux.amoon@gmail.com> Tested-by: Vincent Legoll <legoll@online.fr> # OrangePi-RV2 Tested-by: Gong Shuai <gsh517025@gmail.com> Link: https://patch.msgid.link/20260427-k1-thermal-v5-2-df39187480ed@mailbox.org	2026-06-03 09:12:31 +02:00
