thermal/hwmon: Use the right device for devm_thermal_add_hwmon_sysfs()

2023-07-11T17:39:25+00:00

[ Upstream commit 4a16c190f761cb3a87dcbbf355f91c71ce1f8c0b ] The devres variant of thermal_add_hwmon_sysfs() only takes the thermal zone structure pointer as parameter. Actually, it uses the tz->device to add it in the devres list. It is preferable to use the device registering the thermal zone instead of the thermal zone device itself. That prevents the driver accessing the thermal zone structure internals and it is from my POV more correct regarding how devm_ is used.

Revert "thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe"

2023-07-01T11:14:47+00:00

commit 86edac7d3888c715fe3a81bd61f3617ecfe2e1dd upstream. This reverts commit f05c7b7d9ea9477fcc388476c6f4ade8c66d2d26. That change was causing a regression in the generic-adc-thermal-probed bootrr test as reported in the kernelci-results list [1]. A proper rework will take longer, so revert it for now.

thermal/drivers/mediatek: Use devm_of_iomap to avoid resource leak in mtk_thermal_probe

2023-05-11T14:17:36+00:00

[ Upstream commit f05c7b7d9ea9477fcc388476c6f4ade8c66d2d26 ] Smatch reports: 1. mtk_thermal_probe() warn: 'apmixed_base' from of_iomap() not released. 2. mtk_thermal_probe() warn: 'auxadc_base' from of_iomap() not released. The original code forgets to release iomap resource when handling errors, fix it by switch to devm_of_iomap.

thermal/drivers/mediatek/lvts_thermal: Fix sensor 1 interrupt status bitmask

2023-05-11T14:17:06+00:00

[ Upstream commit 13f03bcd02e4b0498c8ccb066b4eddf61dee6681 ] The binary representation for sensor 1 interrupt status was incorrectly assembled, when compared to the full table given in the same comment section. The conversion into hex was also incorrect, leading to incorrect interrupt status bitmask for sensor 1. This would cause the driver to incorrectly identify changes for sensor 1, when in fact it was sensor 0, or a sensor access time out. Fix the binary and hex representations in the comments, and the actual bitmask macro.

thermal/drivers/mediatek: Add the Low Voltage Thermal Sensor driver

2023-02-15T16:28:42+00:00

The Low Voltage Thermal Sensor (LVTS) is a multiple sensors, multi controllers contained in a thermal domain. A thermal domains can be the MCU or the AP. Each thermal domains contain up to seven controllers, each thermal controller handle up to four thermal sensors. The LVTS has two Finite State Machines (FSM), one to handle the functionin temperatures range like hot or cold temperature and another one to handle monitoring trip point. The FSM notifies via interrupts when a trip point is crossed. The interrupt is managed at the thermal controller level, so when an interrupt occurs, the driver has to find out which sensor triggered such an interrupt. The sampling of the thermal can be filtered or immediate. For the former, the LVTS measures several points and applies a low pass filter.
