A fairly quiet release for SPI, the biggest thing is the conversion to
use GPIO descriptors which is now 90% done but still needs some
stragglers converting.
- Support for inter-word delays.
- Conversion of the core and most drivers to use GPIO descriptors for
GPIO controlled chip selects.
- New drivers for NXP FlexSPI and QuadSPI, SiFive and Spreadtrum.

The bulk of the standout changes in this release are cleanups, with the
core work being a combination of factoring out common code into helpers
and the completion of the conversion of the core to use GPIO
descriptors.
- Addition of helper functions for current limits and conversion of
drivers to use them by Axel Lin.
- Lots and lots of cleanups from Axel Lin.
- Conversion of the core to use GPIO descriptors rather than numbers by
Linus Walleij.

====================
pull-request: bpf-next 2019-03-04
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add AF_XDP support to libbpf. Rationale is to facilitate writing
AF_XDP applications by offering higher-level APIs that hide many
of the details of the AF_XDP uapi. Sample programs are converted
over to this new interface as well, from Magnus.
2) Introduce a new cant_sleep() macro for annotation of functions
that cannot sleep and use it in BPF_PROG_RUN() to assert that
BPF programs run under preemption disabled context, from Peter.
3) Introduce per BPF prog stats in order to monitor the usage
of BPF; this is controlled by kernel.bpf_stats_enabled sysctl
knob where monitoring tools can make use of this to efficiently
determine the average cost of programs, from Alexei.
4) Split up BPF selftest's test_progs similarly as we already
did with test_verifier. This allows to further reduce merge
conflicts in future and to get more structure into our
quickly growing BPF selftest suite, from Stanislav.
5) Fix a bug in BTF's dedup algorithm which can cause an infinite
loop in some circumstances; also various BPF doc fixes and
improvements, from Andrii.
6) Various BPF sample cleanups and migration to libbpf in order
to further isolate the old sample loader code (so we can get
rid of it at some point), from Jakub.
7) Add a new BPF helper for BPF cgroup skb progs that allows
to set ECN CE code point and a Host Bandwidth Manager (HBM)
sample program for limiting the bandwidth used by v2 cgroups,
from Lawrence.
8) Enable write access to skb->queue_mapping from tc BPF egress
programs in order to let BPF pick TX queue, from Jesper.
9) Fix a bug in BPF spinlock handling for map-in-map which did
not propagate spin_lock_off to the meta map, from Yonghong.
10) Fix a bug in the new per-CPU BPF prog counters to properly
initialize stats for each CPU, from Eric.
11) Add various BPF helper prototypes to selftest's bpf_helpers.h,
from Willem.
12) Fix various BPF samples bugs in XDP and tracing progs,
from Toke, Daniel and Yonghong.
13) Silence preemption splat in test_bpf after BPF_PROG_RUN()
enforces it now everywhere, from Anders.
14) Fix a signedness bug in libbpf's btf_dedup_ref_type() to
get error handling working, from Dan.
15) Fix bpftool documentation and auto-completion with regards
to stream_{verdict,parser} attach types, from Alban.

There is no more direct user of this macro; it is only used by
cc-ifversion.
Calling this macro is not efficient since it invokes the compiler to
get the compiler version. CONFIG_GCC_VERSION is already calculated in
the Kconfig stage, so Makefile can reuse it.
Here is a note about the slight difference between cc-version and
CONFIG_GCC_VERSION:
When using Clang, cc-version is evaluated to '0402' because Clang
defines __GNUC__ and __GNUC__MINOR__, and looks like GCC 4.2 in the
version point of view. On the other hand, CONFIG_GCC_VERSION=0
when $(CC) is clang.
There are currently two users of cc-ifversion:
arch/mips/loongson64/Platform
arch/powerpc/Makefile
They are not affected by this change.
The format of cc-version is <major><minor>, while CONFIG_GCC_VERSION
<major><minor><patch>. I adjusted cc-ifversion for the difference of
the number of digits.

The Epson rx8571 is compatible with the Epson rx8581 RTC.
The difference between the rx8571 and rx8581 RTC is that the former has
16 bytes more RAM. This renders them incompatible from a DT point of view.

Sugaya Taichi <sugaya.taichi@socionext.com> explains:
Here is the series of patches the initial support for SC2000(M10V) of
Milbeaut SoCs. "M10V" is the internal name of SC2000, so commonly used in
source code.
SC2000 is a SoC of the Milbeaut series. equipped with a DSP optimized for
computer vision. It also features advanced functionalities such as 360-degree,
real-time spherical stitching with multi cameras, image stabilization for
without mechanical gimbals, and rolling shutter correction. More detail is
below:
https://www.socionext.com/en/products/assp/milbeaut/SC2000.html
Specifications for developers are below:
- Quad-core 32bit Cortex-A7 on ARMv7-A architecture
- NEON support
- DSP
- GPU
- MAX 3GB DDR3
- Cortex-M0 for power control
- NAND Flash Interface
- SD UHS-I
- SD UHS-II
- SDIO
- USB2.0 HOST / Device
- USB3.0 HOST / Device
- PCI express Gen2
- Ethernet Engine
- I2C
- UART
- SPI
- PWM
Support is quite minimal for now, since it only includes timer, clock,
pictrl and serial controller drivers, so we can only boot to userspace
through initramfs. Support for the other peripherals will come eventually.

ARM: multi_v7_defconfig: add ARCH_MILBEAUT and ARCH_MILBEAUT_M10V

On the Fujitsu-A64FX cores ver(1.0, 1.1), memory access may cause
an undefined fault (Data abort, DFSC=0b111111). This fault occurs under
a specific hardware condition when a load/store instruction performs an
address translation. Any load/store instruction, except non-fault access
including Armv8 and SVE might cause this undefined fault.
The TCR_ELx.NFD1 bit is used by the kernel when CONFIG_RANDOMIZE_BASE
is enabled to mitigate timing attacks against KASLR where the kernel
address space could be probed using the FFR and suppressed fault on
SVE loads.
Since this erratum causes spurious exceptions, which may corrupt
the exception registers, we clear the TCR_ELx.NFDx=1 bits when
booting on an affected CPU.

Another batch of changes for ASoC, no big core changes - it's mainly
small fixes and improvements for individual drivers.
- A big refresh and cleanup of the Samsung drivers, fixing a number of
issues which allow the driver to be used with a wider range of
userspaces.
- Fixes for the Intel drivers to make them more standard so less likely
to get bitten by core issues.
- New driver for Cirrus Logic CS35L26.
