When reaching that temperature, the hardware automatically triggers a reset of the entire platform. Some of the thermal zones in x1e80100.dtsi use a critical trip point of 125°C. It's impossible to reach those. It's preferable to shut down the system cleanly before reaching the hardware trip point. Make the critical temperature trip points consistent by setting all of them to 115°C and apply a consistent hysteresis. The ACPI tables also specify 115°C as critical shutdown temperature.

This causes instability issues, as a result of improper reset duration. The fixed regulator device requests the GPIO during probe in its inactive state (except if regulator-boot-on property is set, in which case it is requested in the active state). Considering gpio is GPIO_ACTIVE_LOW for Puma, it means it’s driving it high. Then the regulator gets enabled (because regulator-always-on property), which drives it to its active state, meaning driving it low. The Cypress CYUSB3304 USB hub actually requires the reset to be asserted for at least 5 ms, which we cannot guarantee right now since there's no delay in the current config, meaning the hub may sometimes work or not. We could add delay as offered by fixed-regulator but let's rather fix this by using the proper way to model onboard USB hubs. Define hub_2_0 and hub_3_0 nodes, as the onboard Cypress hub consist of two 'logical' hubs, for USB2.0 and USB3.0. Use the 'reset-gpios' property of hub to assign reset pin instead of using regulator. Rename the vcc5v0_host regulator to cy3304_reset to be more meaningful. Pin is configured to output-high by default, which sets the hub in reset state during pin controller initialization. This allows to avoid double enumeration of devices in case the bootloader has setup the USB hub before the kernel. The vdd-supply and vdd2-supply properties in hub nodes are added to provide correct dt-bindings, although power supplies are always enabled based on HW design.

This causes instability issues, as a result of improper reset duration. The fixed regulator device requests the GPIO during probe in its inactive state (except if regulator-boot-on property is set, in which case it is requested in the active state). Considering gpio is GPIO_ACTIVE_LOW for Puma, it means it’s driving it high. Then the regulator gets enabled (because regulator-always-on property), which drives it to its active state, meaning driving it low. The Cypress CYUSB3304 USB hub actually requires the reset to be asserted for at least 5 ms, which we cannot guarantee right now since there's no delay in the current config, meaning the hub may sometimes work or not. We could add delay as offered by fixed-regulator but let's rather fix this by using the proper way to model onboard USB hubs. Define hub_2_0 and hub_3_0 nodes, as the onboard Cypress hub consist of two 'logical' hubs, for USB2.0 and USB3.0. Use the 'reset-gpios' property of hub to assign reset pin instead of using regulator. Rename the vcc5v0_host regulator to cy3304_reset to be more meaningful. Pin is configured to output-high by default, which sets the hub in reset state during pin controller initialization. This allows to avoid double enumeration of devices in case the bootloader has setup the USB hub before the kernel. The vdd-supply and vdd2-supply properties in hub nodes are added to provide correct dt-bindings, although power supplies are always enabled based on HW design.
