2020-09-29net: caif: Remove unused caif SPI driverThomas Gleixner2-230/+0
While chasing in_interrupt() (ab)use in drivers it turned out that the caif_spi driver has never been in use since the driver was merged 10 years ago. There never was any matching code which provides a platform device. The driver has not seen any update (asided of treewide changes and cleanups) since 8 years and the maintainers vanished from the planet. So analysing the potential contexts and the (in)correctness of in_interrupt() usage is just a pointless exercise. Remove the cruft.

PCI devices support two variants of the D3 power state: D3hot (main power present) D3cold (main power removed). Previously struct pci_dev contained: unsigned int d3_delay; /* D3->D0 transition time in ms */ unsigned int d3cold_delay; /* D3cold->D0 transition time in ms */ "d3_delay" refers specifically to the D3hot state. Rename it to "d3hot_delay" to avoid ambiguity and align with the ACPI "_DSM for Specifying Device Readiness Durations" in the PCI Firmware spec r3.2, sec 4.6.9. There is no change to the functionality.

CONFIG_EFI_VARS controls the code that exposes EFI variables via sysfs entries, which was deprecated before support for non-Intel architectures was added to EFI. So let's limit its availability to Intel architectures for the time being, and hopefully remove it entirely in the not too distant future. While at it, let's remove the module alias so that the module is no longer loaded automatically. Signed-off-by: Ard Biesheuvel <ardb@kernel.org>

This binding is non trivial due to the range of different parts supported having several subtle quirks. Martin has helped clarify some of them. Note, I haven't restricted the amlogic,hhi-sysctrl to only be present on the relevant parts if nvmem stuff also is, but it would seem to be rather odd if it were otherwise. Perhaps we look to make this binding more restrictive at a later date.

There are behavioural requirements on the seq_file next() function in terms of how it updates *pos at end-of-file, and these are now enforced by a warning. I was recently attempting to justify the reason this was needed, and couldn't remember the details, and didn't find them in the documentation. So I re-read the code until I understood it again, and updated the documentation to match. I also enhanced the text about SEQ_START_TOKEN as it seemed potentially misleading.

2020-09-28perf: Add Arm CMN-600 PMU driverRobin Murphy2-0/+66
Initial driver for PMU event counting on the Arm CMN-600 interconnect. CMN sports an obnoxiously complex distributed PMU system as part of its debug and trace features, which can do all manner of things like sampling, cross-triggering and generating CoreSight trace. This driver covers the PMU functionality, plus the relevant aspects of watchpoints for simply counting matching flits.

2020-09-28perf: Add Arm CMN-600 DT bindingRobin Murphy1-0/+57
Document the requirements for the CMN-600 DT binding. The internal topology is almost entirely discoverable by walking a tree of ID registers, but sadly both the starting point for that walk and the exact format of those registers are configuration-dependent and not discoverable from some sane fixed location. Oh well. Signed-off-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Will Deacon <will@kernel.org>

2020-09-28ARM: dts: bcm2835: Change firmware compatible from simple-bus to simple-mfdMaxime Ripard1-2/+2
The current binding for the RPi firmware uses the simple-bus compatible as a fallback to benefit from its automatic probing of child nodes. However, simple-bus also comes with some constraints, like having the ranges, our case. Let's switch to simple-mfd that provides the same probing logic without those constraints.
