2020-09-04thermal: ti-soc-thermal: Fix bogus thermal shutdowns for omap4430Tony Lindgren
We can sometimes get bogus thermal shutdowns on omap4430 at least with droid4 running idle with a battery charger connected: thermal thermal_zone0: critical temperature reached (143 C), shutting down Dumping out the register values shows we can occasionally get a 0x7f value that is outside the TRM listed values in the ADC conversion table. And then we get a normal value when reading again after that. Reading the register multiple times does not seem help avoiding the bogus values as they stay until the next sample is ready. Looking at the TRM chapter "18.4.10.2.3 ADC Codes Versus Temperature", we should have values from 13 to 107 listed with a total of 95 values. But looking at the omap4430_adc_to_temp array, the values are off, and the end values are missing. And it seems that the 4430 ADC table is similar to omap3630 rather than omap4460. Let's fix the issue by using values based on the omap3630 table and just ignoring invalid values. Compared to the 4430 TRM, the omap3630 table has the missing values added while the TRM table only shows every second value. Note that sometimes the ADC register values within the valid table can also be way off for about 1 out of 10 values. But it seems that those just show about 25 C too low values rather than too high values. So those do not cause a bogus thermal shutdown.

And it can possibly be used for questions that don't enable code on their own, but are used to enable or disable a whole slew of other questions.

It is known that Mediatek owns two thermal systems, which only differ in the way of reading calibration data and converting temperature.

This can lead to a subsequent crash because a valid pointer is returned to the called, but dereferencing that pointer as struct thermal_zone is not safe.

2020-07-21thermal: rcar_gen3_thermal: Do not shadow thcode variableNiklas Söderlund
The function rcar_gen3_thermal_calc_coefs() takes an argument called 'thcode' which shadows the static global 'thcode' variable. This is not harmful but bad for readability and is harmful for planned changes to the driver. The THCODE values should be read from hardware fuses if they are available and only fallback to the global 'thcode' variable if they are not fused. Rename the global 'thcode' variable to 'thcodes' to avoid shadowing the symbol in functions that take it as an argument.

2020-07-21thermal: core: Move initialization after core initcallDaniel Lezcano

The initcalls like to play joke. In our case, the thermal-netlink initcall is called after the thermal-core initcall but this one sends a notification before the former is initialized. No issue was spotted, but it could lead to a memory corruption, so instead of relying on the core_initcall for the thermal-netlink, let's initialize directly from the thermal-core init routine, so we have full control of the init ordering.

When the network is not configured, the netlink is disabled on all the system. The thermal framework assumed the netlink is always opt-in. Fix this by adding a Kconfig option for the netlink notification, defaulting to yes and depending on CONFIG_NET. As the change implies multiple stubs and in order to not pollute the internal thermal header, the thermal_nelink.h has been added and included in the thermal_core.h, so this one regain some kind of clarity.

This reverts commit eb9aecd90d1a39601e91cd08b90d5fee51d321a6 The above patch is supposed to fix a register index error on mt2701. It is not clear if the problem solved is a hang or just an invalid value returned, my guess is the second. The patch introduces, though, a new hang on MT8173 device making them unusable. So, seems reasonable, revert the patch because introduces a worst issue. The reason I send a revert instead of trying to fix the issue for MT8173 is because the information needed to fix the issue is in the datasheet and is not public. So I am not really able to fix it. Fixes the following bug when CONFIG_MTK_THERMAL is set on MT8173 devices.
