2021-10-07thermal/drivers/netlink: Add the temperature when crossing a trip pointDaniel Lezcano
The slope of the temperature increase or decrease can be high and when the temperature crosses the trip point, there could be a significant difference between the trip temperature and the measured temperatures. That forces the userspace to read the temperature back right after receiving a trip violation notification. In order to be efficient, give the temperature which resulted in the trip violation.

2020-07-21thermal: netlink: Improve the initcall orderingDaniel 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.

2020-07-21thermal: netlink: Fix compilation error when CONFIG_NET=nDaniel Lezcano
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.
