Merge tag 'thermal-v6.16-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux

Merge updates of multiple thermal drivers for 6.16 from Daniel Lezcano:

"- Make the Hisilicon driver to compile by default when ARCH_HISI is
set (Krzysztof Kozlowski)

- Cleanup printk format with use of %pC instead of %pCn in the bcm2835
driver (Luca Ceresoli)

- Fix variable naming coding style in the AmLogic driver (Enrique
Isidoro Vazquez Ramos)

- Fix missing debugfs entry removal on failure by using the devm_
variant in the LVTS driver (AngeloGioacchino Del Regno)

- Remove the unused lvts_debugfs_exit() function as the devm variant
introduced before takes care of removing the debugfs entry in the
LVTS driver (Arnd Bergmann)

- Add the Airoha EN7581 thermal sensor support along with its DT
bindings (Christian Marangi)

- Add ipq5018 compatible string DT binding, cleanup and add its suppot
in the QCom Tsens driver driver (Sricharan Ramabadhran and George
Moussalem)

- Fix comments typos in the Airoha driver (Christian Marangi)"
