2024-01-02thermal/drivers/exynos: Use set_trips opsMateusz Majewski
Currently, each trip point defined in the device tree corresponds to a single hardware interrupt. This commit instead switches to using two hardware interrupts, whose values are set dynamically using the set_trips callback. Additionally, the critical temperature threshold is handled specifically. Setting interrupts in this way also fixes a long-standing lockdep warning, which was caused by calling thermal_zone_get_trips with our lock being held. Do note that this requires TMU initialization to be split into two parts, as done by the parent commit: parts of the initialization call into the thermal_zone_device structure and so must be done after its registration, but the initialization is also responsible for setting up calibration, which must be done before thermal_zone_device registration, which will call set_trips for the first time; if the calibration is not done in time, the interrupt values will be silently wrong!

2024-01-02thermal/drivers/exynos: Stop using the threshold mechanism on Exynos 4210Mateusz Majewski
Exynos 4210 supports setting a base threshold value, which is added to all trip points. This might be useful, but is not really necessary in our usecase, so we always set it to 0 to simplify the code a bit. Additionally, this change makes it so that we convert the value to the calibrated one in a slightly different place. This is more correct morally, though it does not make any change when single-point calibration is being used (which is the case currently).

2024-01-02thermal/thermal_of: Allow rebooting after critical tempFabio Estevam
Currently, the default mechanism is to trigger a shutdown after the critical temperature is reached. In some embedded cases, such behavior does not suit well, as the board may be unattended in the field and rebooting may be a better approach. The bootloader may also check the temperature and only allow the boot to proceed when the temperature is below a certain threshold. Introduce support for allowing a reboot to be triggered after the critical temperature is reached. If the "critical-action" devicetree property is not found, fall back to the shutdown action to preserve the existing default behavior. If a custom ops->critical exists, then it takes preference over critical-actions. Tested on a i.MX8MM board with the following devicetree changes: thermal-zones { cpu-thermal { critical-action = "reboot"; }; }; Signed-off-by: Fabio Estevam <festevam@denx.de> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20231129124330.519423-4-festevam@gmail.com

That routine appears to only be using devm to avoid goto statements. The new __free() annotation at variable declaration time can achieve the same effect more efficiently.

This patch adds support for each available OTP variant of the device. The OTP configuration cannot be read over I2C, so it is derived from a compatible string instead. Early revisions of the D0 order code require their OTP-enabled func- tionality to be manually restored following a soft reset; this patch accommodates this erratum as well.

2024-01-01Input: iqs269a - add support for slider gesturesJeff LaBundy
This patch adds support for slider gestures that can be expressed by the device. Each gesture (e.g. tap or hold) can be mapped to a unique keycode for either slider 0 or 1. With this change, raw slider coordinates are reported only if the slider has no keycodes defined. This prevents unwanted mouse cur- sor movement when expressing axial gestures (e.g. swipe) and also eliminates some unnecessary I2C traffic. Different revisions of silicon use different tap and swipe timeout step sizes. Apply an appropriate scaling factor depending on which revision is found. To facilitate this change, store the iqs269_ver_info struct in the driver's private data so that other functions can use it after the driver has probed. Last but not least, a former reserved field in iqs269_ver_info now contains useful information; give it a name (fw_num).
