From 11e2e36c06cb2c443366fe3c31193b011a161251 Mon Sep 17 00:00:00 2001 From: Runyang Chen Date: Tue, 10 May 2022 20:13:50 +0800 Subject: soc/mediatek/mt8186: Enable thermal hardware reset Under the current watchdog setting, the system will not reboot when the temperature is too high. To enable thermal hardware reset, we need to enable thermal control request and set it to reboot mode. Note that because thermal throttle (by lowering cpu frequency) is currently enabled, the thermal hardware reset shouldn't be triggered under normal circumstances. This feature is only for new hardware structure for thermal. Therefore, we only need to apply it on MT8192/MT8195/MT8186. This setting is based on thermal and watchdog section of MT8186 Function Specification. BUG=none TEST=emerge-corsola coreboot TEST=thermal hardware reset is working.
