2019-12-10arm64: dts: allwinner: sun50i-h6-pine-h64: state that the DT supports the modelACorentin Labbe1-3/+14
The current sun50i-h6-pine-h64 DT does not specify which model (A or B) it supports. When this file was created, only modelA was existing, but now both model exists and with the time, this DT drifted to support the model B since it is the most common one. Furtheremore, some part of the model A does not work with it like ethernet and HDMI connector (as confirmed by Jernej on IRC). So it is time to settle the issue, and the easiest way was to state that this DT is for model B. Easiest since only a small name changes is required. Doing the opposite (stating this file is for model A) will add changes (for ethernet and HDMI) and so, will break too many setup. But as asked by the maintainer this patch state this file is for model A. In the process this patch adds the missing compoments to made it work on model A.

2019-12-09arm64: dts: rockchip: Fix NanoPC-T4 cooling mapsRobin Murphy1-27/+0
Although it appeared to follow logically from the bindings, apparently the thermal framework can't properly cope with a single cooling device being shared between multiple maps. The CPU zone is probably easier to overheat, so remove the references to the (optional) fan from the GPU cooling zone to avoid things getting confused. Hopefully GPU-intensive tasks will leak enough heat across to the CPU zone to still hit the fan trips before reaching critical GPU temperatures.

2019-12-09arm64: dts: imx8qxp: Remove unnecessary "interrupt-parent" propertyAnson Huang1-12/+0
gic is appointed as default interrupt parent for devices, so no need to specify it again in device nodes which use it as interrupt parent. Signed-off-by: Anson Huang <Anson.Huang@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2019-12-08sched/rt, arm64: Use CONFIG_PREEMPTIONThomas Gleixner6-33/+36
CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same functionality which today depends on CONFIG_PREEMPT. Switch the Kconfig dependency, entry code and preemption handling over to use CONFIG_PREEMPTION. Add PREEMPT_RT output in show_stack().
