Now CONFIG_OF can be enabled on sh:
drivers/of/irq.c:472:8: error: redefinition of 'struct intc_desc'
include/linux/sh_intc.h:109:8: note: originally defined here
As "intc_desc" is used all over the place in sh platform code, while
drivers/of/irq.c has a local definition used in a single function,
rename the latter by prefixing it with "of_".

of_irq_parse_raw() needs to return the correct interrupt controller
node when an interrupt-map property doesn't exist.
It allows of_irq_parse_raw() to return the node pointer of the interrupt
controller, rather than the parent bus. This allows ics_rtas_host_match()
to detect that the controller is a legacy 8259 and avoid using xics.
This avoids an RTAS assertion/crash during early kernel bootstrapping.

Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.2.
I've one other new driver from freescale on my radar, it's been posted
and reviewed, I'd just like to get someone to give it a last look, so
maybe I'll send it or maybe I'll leave it.
There is no major nouveau changes in here, Ben was working on
something big, and we agreed it was a bit late, there wasn't anything
else he considered urgent to merge.
There might be another msm pull for some bits that are waiting on
arm-soc, I'll see how we time it.
This touches some "of" stuff, acks are in place except for the fixes
to the build in various configs,t hat I just applied.
Summary:
New drivers:
- virtio-gpu:
KMS only pieces of driver for virtio-gpu in qemu.
This is just the first part of this driver, enough to run
unaccelerated userspace on. As qemu merges more we'll start
adding the 3D features for the virgl 3d work.
- amdgpu:
a new driver from AMD to driver their newer GPUs. (VI+)
It contains a new cleaner userspace API, and is a clean
break from radeon moving forward, that AMD are going to
concentrate on. It also contains a set of register headers
auto generated from AMD internal database.
core:
- atomic modesetting API completed, enabled by default now.
- Add support for mode_id blob to atomic ioctl to complete interface.
- bunch of Displayport MST fixes
- lots of misc fixes.

Pull arm64 updates from Catalin Marinas:
"Mostly refactoring/clean-up:
- CPU ops and PSCI (Power State Coordination Interface) refactoring
following the merging of the arm64 ACPI support, together with
handling of Trusted (secure) OS instances
- Using fixmap for permanent FDT mapping, removing the initial dtb
placement requirements (within 512MB from the start of the kernel
image). This required moving the FDT self reservation out of the
memreserve processing
- Idmap (1:1 mapping used for MMU on/off) handling clean-up
- Removing flush_cache_all() - not safe on ARM unless the MMU is off.
Last stages of CPU power down/up are handled by firmware already
- "Alternatives" (run-time code patching) refactoring and support for
immediate branch patching, GICv3 CPU interface access
- User faults handling clean-up
And some fixes:
- Fix for VDSO building with broken ELF toolchains
- Fix another case of init_mm.pgd usage for user mappings (during
ASID roll-over broadcasting)
- Fix for FPSIMD reloading after CPU hotplug

The DT unittest currently requires an arch (typically) to select
OF_EARLY_FLATTREE. Remove this dependency by selecting it directly so that
the unittest can be enabled easily on any architecture. With this and the

defconfig rather than hunting for the combination of config options to
enable OF on x86.

This splits off the reservation of the memory occupied by the FDT
binary itself from the processing of the memory reservations it
contains. This is necessary because the physical address of the FDT,
which is needed to perform the reservation, may not be known to the
FDT driver core, i.e., it may be mapped outside the linear direct
mapping, in which case __pa() returns a bogus value.

Commit 5590f3196b29 ("drivers/core/of: Add symlink to device-tree from
devices with an OF node") adds the symlink `of_node` for each device
pointing to it's device tree node while creating/initialising it.
However the devicetree sysfs is created and setup in of_init which is
executed at core_initcall level. For all the devices created before
of_init, the following error is thrown:
"Error -2(-ENOENT) creating of_node link"

41f8bba7f555 ("of/pci: Add pci_register_io_range() and
pci_pio_to_address()") added support for systems with several I/O ranges
described by OF bindings. It modified pci_address_to_pio() look up the
io_range for a given CPU physical address, but the conversion was wrong.
Fix the conversion of address to I/O port.

Some Ethernet PHY devices/switches may not properly release the MDIO bus
during turn-around time, and fail to drive it low, which can be seen by
some controllers as a read failure, while the data clocked in is still
correct.
Add a boolean property "broken-turn-around" which is parsed by the
generic MDIO bus probing code and will set the corresponding bit in the
MDIO bus phy_ignore_ta_mask bitmask for MDIO bus drivers to utilize that
information.

This defines a new compatible option for MFD devices "simple-mfd" that will
make the OF core spawn child devices for all subnodes of that MFD device.
It is optional but handy for things like syscon and possibly other
simpler MFD devices.
Since there was no file to put the documentation in, I took this opportunity
to make a small writeup on MFD devices and add the compatible definition
there.

8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
up route lookups even further. From Alexander Duyck.
9) Many improvements and bug fixes to the rhashtable implementation,
from Herbert Xu and Thomas Graf. In particular, in the case where
an rhashtable user bulk adds a large number of items into an empty
table, we expand the table much more sanely.

Biederman.
11) Extend EBPF to access SKB fields, from Alexei Starovoitov.
12) Split out new connection request sockets so that they can be

hash lookups go direct to the request sockets instead of having to
go first to the listener then to the request socks hashed
underneath. From Eric Dumazet.
13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.

SoC peripherals can come in several different flavors:
- little-endian: registers always need to be accessed in LE mode (so the
kernel should perform a swap if the CPU is running BE)
- big-endian: registers always need to be accessed in BE mode (so the
kernel should perform a swap if the CPU is running LE)
- native-endian: the bus will automatically swap accesses, so the kernel
should never swap
Introduce a function that checks an OF device node to see whether it
contains a "big-endian" or "native-endian" property. For the former case,
always return true. For the latter case, return true iff the kernel was
built for BE (implying that the BE MMIO accessors do not perform a swap).
Otherwise return false, assuming LE registers.
LE registers are assumed by default because most existing drivers (libahci,
serial8250, usb) always use readl/writel in the absence of instructions
to the contrary, so that will be our fallback.

Commit 51975db0b7333 ("of/flattree: merge early_init_dt_scan_memory()
common code") consolidated some code from PowerPC (typically
big-endian), and ended-up adding a pr_debug() printing reg properties in
big-endian (DT native) format, not CPU endian.
This debug print suffers from two problems:
- we only print 4 "reg" values, while there could be more on typical
systems having multiple memory ranges
- we print these 4 "reg" values in FDT endianess, that is big-endian,
and these values could be confusing for little-endian configurations
Since we are already printing the base address and size of the memory
regions parsed by early_init_dt_scan_memory() later in a way that is
both endian correct, and takes into account arbitrary number of memory
banks, just remove that part of the debug print.

The previous commit, "of/unittest: early return from test skips tests"
exposed broken tests for the of_platform_unpopulate() function. The
problem was the populate and depopulate calls were not symmetrical like
they were intended to be, and unpopulate depends on the parent device to
have it's of_node pointer pointing to the parent device node. Fix these
bugs so that the test case works correctly.
In the process, the test_bus used as a container for the test devices
has been changed from a statically allocated struct device (which is
bad) to a properly allocated device with a .release() method (which is
good). This stops the test code from being a bad example of abusing the
device model.

of_get_mac_address() basically does the same thing thrice, every time with a
different property name, so it makes sense to factor out the repetitive code
into separate function. While at it, we can start using ETH_ALEN instead of the
bare number and drop unnecessary parens around the property length check.
The resulting ARM object file is 100 bytes less in size than before the patch.
