request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.Hence replace setup_irq() by request_irq().
remove_irq() has been replaced by free_irq() as well.
There were build error's during previous version, couple of which was
reported by kbuild test robot of which one was reported
by Thomas Bogendoerfer as well. There were a
few more issues including build errors, those also have been fixed.[1] https://lkml.kernel.org/r/alpine.DEB.2.20.1710191609480.1971@nanos

This flag was historically used to indicate that a clk is a "basic" type
of clk like a mux, divider, gate, etc. This never turned out to be very
useful though because it was hard to cleanly split "basic" clks from
other clks in a system. This one flag was a way for type introspection
and it just didn't scale. If anything, it was used by the TI clk driver
to indicate that a clk_hw wasn't contained in the SoC specific clk
structure. We can get rid of this define now that TI is finding those
clks a different way.Cc: Tero Kristo

"A few early MIPS fixes for 4.21:- The Broadcom BCM63xx platform sees a fix for resetting the BCM6368
ethernet switch, and the removal of a platform device we've never
had a driver for.- The Alchemy platform sees a few fixes for bitrot that occurred
within the past few cycles.- We now enable vectored interrupt support for the MediaTek MT7620
SoC, which makes sense since they're supported by the SoC but in
this case also works around a bug relating to the location of
exception vectors when using a recent version of U-Boot.- The atomic64_fetch_*_relaxed() family of functions see a fix for a
regression in MIPS64 kernels since v4.19.- Cavium Octeon III CN7xxx systems will now disable their RGMII
interfaces rather than attempt to enable them & warn about the lack
of support for doing so, as they did since initial CN7xxx ethernet
support was added in v4.7.- The Microsemi/Microchip MSCC SoCs gain a MAINTAINERS entry.

The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.The Coccinelle script used for this was:

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:kmalloc(a * b, gfp)
with:
kmalloc_array(a * b, gfp)as well as handling cases of:
kmalloc(a * b * c, gfp)
with:
kmalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kmalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kmalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().The Coccinelle script used for this was:
// Fix redundant parens around sizeof().

This converts the bit-banged GPIO SPI driver to looking up and
using GPIO descriptors to get a handle on GPIO lines for SCK,
MOSI, MISO and all CS lines.All existing board files are converted in one go to keep it all
consistent. With these conversions I rarely find any interrim
steps that makes any sense.Device tree probing and GPIO handling should work like before
also after this patch.For board files, we stop using controller data to pass the GPIO
line for chip select, instead we pass this as a GPIO descriptor
lookup like everything else.In some s3c24xx machines the names of the SPI devices were set to
"spi-gpio" rather than "spi_gpio" which can never have worked, I
fixed it working (I guess) as part of this patch set. Sometimes
I wonder how this code got upstream in the first place, it
obviously is not tested.mach-s3c64xx/mach-smartq.c has the same problem and additionally
defines the *same* GPIO line for MOSI and MISO which is not going
to be accepted by gpiolib. As the lines were number 1,2,2 I assumed
it was a typo and use lines 1,2,3. A comment gives awat that line 0
is chip select though no actual SPI device is provided for the LCD
supposed to be on this bit-banged SPI bus. I left it intact instead
of just deleting the bus though.Kill off board file code that try to initialize the SPI lines
to the same values that they will later be set by the spi_gpio
driver anyways. Given the huge number of weird things in these
board files I do not think this code is very tested or put in
with much afterthought anyways.In order to assert that we do not get performance regressions on
this crucial bing-banged driver, a ran a script like this dumping the
Ilitek ILI9322 regmap 10000 times (it has no caching obviously) on
an otherwise idle system in two iterations before and after the
patches:#!/bin/sh
for run in `seq 10000`
do
cat /debug/regmap/spi0.0/registers > /dev/null
doneBefore the patch:
time test.sh
real 3m 41.03s
user 0m 29.41s
sys 3m 7.22stime test.sh
real 3m 44.24s
user 0m 32.31s

sys 3m 8.08stime test.sh
real 3m 39.92s

"This contains two bigger than usual tree-wide changes this time. They
all have proper acks, caused no merge conflicts in linux-next where
they have been for a while. They are namely:- to-gpiod conversion of the i2c-gpio driver and its users (touching
arch/* and drivers/mfd/*)- adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)Other notable changes:
- i2c_boardinfo can now carry a dev_name to be used when the device
is created. This is because some devices in ACPI world need fixed
names to find the regulators.- the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.- at24 driver has way better OF support. And it has a new maintainer.
