w1: w1-gpio: Convert to use GPIO descriptors
The w1 master driver includes a complete open drain emulation reimplementation among other things. This converts the driver and all board files using it to use GPIO descriptors associated with the device to look up the GPIO wire, as well ass the optional pull-up GPIO line. When probed from the device tree, the driver will just pick descriptors and use them right off. For the two board files in the kernel, we add descriptor lookups so we do not need to keep any old platform data handling around for the GPIO lines. As the platform data is also a state container for this driver, we augment it to contain the GPIO descriptors. w1_gpio_write_bit_dir() and w1_gpio_write_bit_val() are gone since this pair was a reimplementation of open drain emulation which is now handled by gpiolib. The special "linux,open-drain" flag is a bit of mishap here: it has the same semantic as the same flags in I2C: it means that something in the platform is setting up the line as open drain behind our back. We handle this the same way as in I2C. To drive the pull-up, we need to bypass open drain emulation in gpiolib for the line, and this is done by driving it high using gpiod_set_raw_value() which has been augmented to have the semantic of overriding the open drain emulation. We also augment the documentation to reflect the way to pass GPIO descriptors from the machine. Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |

treewide: Switch DEFINE_TIMER callbacks to struct timer_list *
This changes all DEFINE_TIMER() callbacks to use a struct timer_list
pointer instead of unsigned long. Since the data argument has already been
removed, none of these callbacks are using their argument currently, so
this renames the argument to "unused".
Done using the following semantic patch:
@match_define_timer@
declarer name DEFINE_TIMER;
identifier _timer, _callback;
@@
DEFINE_TIMER(_timer, _callback);
@change_callback depends on match_define_timer@

Merge branch 'i2c/for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"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.
Thanks Bartosz for stepping up!
The rest is regular driver updates and fixes"

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

i2c: gpio: Augment all boardfiles to use open drain
We now handle the open drain mode internally in the I2C GPIO driver, but we will get warnings from the gpiolib that we override the default mode of the line so it becomes open drain. We can fix all in-kernel users by simply passing the right flag along in the descriptor table, and we already touched all of these files in the series so let's just tidy it up.

i2c: gpio: Convert to use descriptors
This converts the GPIO-based I2C-driver to using GPIO descriptors instead of the old global numberspace-based GPIO interface. We: - Convert the driver to unconditionally grab two GPIOs from the device by index 0 (SDA) and 1 (SCL) which will work fine with device tree and descriptor tables. The existing device trees will continue to work just like before, but without any roundtrip through the global numberspace. - Brutally convert all boardfiles still passing global GPIOs by registering descriptor tables associated with the devices instead so this driver does not need to keep supporting passing any GPIO numbers as platform data. There is no stepwise approach as elegant as this, I strongly prefer this big hammer over any antsteps for this conversion. This way the old GPIO numbers go away and NEVER COME BACK. Special conversion for the different boards utilizing I2C-GPIO: - EP93xx (arch/arm/mach-ep93xx): pretty straight forward as all boards were using the same two GPIO lines, just define these two in a lookup table for "i2c-gpio" and register these along with the device. None of them define any other platform data so just pass NULL as platform data. This platform selects GPIOLIB so all should be smooth. The pins appear on a gpiochip for bank "G" as pins 1 (SDA) and 0 (SCL). - IXP4 (arch/arm/mach-ixp4): descriptor tables have to be registered for each board separately. They all use "IXP4XX_GPIO_CHIP" so it is pretty straight forward. Most board define no other platform data than SCL/SDA so they can drop the #include of <linux/i2c-gpio.h> and assign NULL to platform data. The "goramo_mlr" (Goramo Multilink Router) board is a bit worrisome: it implements its own I2C bit-banging in the board file, and optionally registers an I2C serial port, but claims the same GPIO lines for itself in the board file. This is not going to work: there will be competition for the GPIO lines, so delete the optional extra I2C bus instead, no I2C devices are registered on it anyway, there are just hints that it may contain an EEPROM that may be accessed from userspace. This needs to be fixed up properly by the serial clock using I2C emulation so drop a note in the code. - KS8695 board acs5k (arch/arm/mach-ks8695/board-acs5.c) has some platform data in addition to the pins so it needs to be kept around sans GPIO lines. Its GPIO chip is named "KS8695" and the arch selects GPIOLIB. - PXA boards (arch/arm/mach-pxa/*) use some of the platform data so it needs to be preserved here. The viper board even registers two GPIO I2Cs. The gpiochip is named "gpio-pxa" and the arch selects GPIOLIB. - SA1100 Simpad (arch/arm/mach-sa1100/simpad.c) defines a GPIO I2C bus, and the arch selects GPIOLIB. - Blackfin boards (arch/blackfin/bf533 etc) for these I assume their I2C GPIOs refer to the local gpiochip defined in arch/blackfin/kernel/bfin_gpio.c names "BFIN-GPIO". The arch selects GPIOLIB. The boards get spiked with IF_ENABLED(I2C_GPIO) but that is a side effect of it being like that already (I would just have Kconfig select I2C_GPIO and get rid of them all.) I also delete any platform data set to 0 as it will get that value anyway from static declartions of platform data. - The MIPS selects GPIOLIB and the Alchemy machine is using two local GPIO chips, one of them has a GPIO I2C. We need to adjust the local offset from the global number space here. The ATH79 has a proper GPIO driver in drivers/gpio/gpio-ath79.c and AFAICT the chip is named "ath79-gpio" and the PB44 PCF857x expander spawns from this on GPIO 1 and 0. The latter board only use the platform data to specify pins so it can be cut altogether after this. - The MFD Silicon Motion SM501 is a special case. It dynamically spawns an I2C bus off the MFD using sm501_create_subdev(). We use an approach to dynamically create a machine descriptor table and attach this to the "SM501-LOW" or "SM501-HIGH" gpiochip. We use chip-local offsets to grab the right lines. We can get rid of two local static inline helpers as part of this refactoring.

An empty macro definition can cause unexpected behavior, in case of the ixp4xx ioport_unmap, we get two warnings: drivers/net/wireless/marvell/libertas/if_cs.c: In function 'if_cs_release': drivers/net/wireless/marvell/libertas/if_cs.c:826:3: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] ioport_unmap(card->iobase); drivers/vfio/pci/vfio_pci_rdwr.c: In function 'vfio_pci_vga_rw': drivers/vfio/pci/vfio_pci_rdwr.c:230:15: error: the omitted middle operand in ?: will always be 'true', suggest explicit middle operand [-Werror=parentheses] is_ioport ? ioport_unmap(iomem) : iounmap(iomem); This uses an inline function to define the macro in a safer way.

ARM: ixp4xx: use normal prototype for {read,write}s{b,w,l}
ixp4xx defines the arguments to its __indirect_writesb() and other functions as pointers to fixed-size data. This is not necessarily wrong, and it works most of the time, but it causes warnings in at least one driver: drivers/net/ethernet/smsc/smc91x.c: In function 'smc_rcv': drivers/net/ethernet/smsc/smc91x.c:495:21: error: passing argument 2 of '__indirect_readsw' from incompatible pointer type [-Werror=incompatible-pointer-types] SMC_PULL_DATA(lp, data, packet_len - 4); All other definitions of the same functions pass void pointers, so doing the same here avoids the warnings.

This is the bulk of GPIO changes for kernel v4.6:
Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model. We now finally make GPIO chips
devices. The gpio_chip will create a gpio_device which contains
a struct device, and this gpio_device struct is kept private.
Anything that needs to be kept private from the rest of the kernel
will gradually be moved over to the gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step
of a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices. We can now discover GPIOs properly from
userspace. We still have not come up with a way to actually *use*
GPIOs from userspace.
- To encourage people to use the character device for the future,
we have it always-enabled when using GPIO. The old sysfs ABI is
still opt-in (and can be used in parallel), but is marked as
deprecated. We will keep it around for the foreseeable future,
but it will not be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes. This dates back to when GPIO was an opt-in feature and
no shared library even existed: just a header file with proper
prototypes was provided and all semantics were up to the arch to
implement. These patches make the GPIO chip even more a proper
device and cleans out leftovers of the old in-kernel API here
and there. Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going
on, but we now return sane values in the vast majority of drivers
and the errorpath is sanitized. Some patches for powerpc, blackfin
and unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected
to SPI to obtain a dirt-cheap output-only GPIO expander.

usb: gadget: pxa25x_udc: move register definitions from arch
ixp4xx and pxa25x both use this driver and provide a slightly
different set of register definitions for it. Aside from that,
the definition in the ixp4xx-regs.h header conflicts with the
on in the pxa27x device driver when compile-testing that:
In file included from ../drivers/usb/gadget/udc/pxa27x_udc.c:37:0:
../drivers/usb/gadget/udc/pxa27x_udc.h:26:0: warning: "UDCCR" redefined
#define UDCCR 0x0000 /* UDC Control Register */
^
In file included from ../arch/arm/mach-ixp4xx/include/mach/hardware.h:27:0,
from ../arch/arm/mach-ixp4xx/include/mach/io.h:18,

#define UDCCR IXP4XX_USB_REG(IXP4XX_USB_BASE_VIRT+0x0000)
This addresses both issues by moving all the definitions into the
pxa25x_udc driver itself. It turns out the only difference between
them was 'UDCCS_IO_ROF', and that could well be a mistake when it
was incorrectly copied from pxa25x to ixp4xx.

MTD updates for v4.5:
Generic MTD
* populate the MTD device 'of_node' field (and get a proper 'of_node' symlink
in sysfs)
- This yielded some new helper functions, and changes across a variety of
drivers
* partitioning cleanups, to prepare for better device-tree based partitioning
in the future
- Eliminate a lot of boilerplate for drivers that want to use OF-based
partition parsing
- The DT bindings for this didn't settle yet, so most non-cleanup portions
are deferred for a future release
NAND
* embed a struct mtd_info inside struct nand_chip
- This is really long overdue; too many drivers have to do the same silly
boilerplate to allocate and link up two "independent" structs, when in
fact, everyone is assuming there is an exact 1:1 relationship between a
NAND chips struct and its underlying MTD. This aids improved helpers and
should make certain abstractions easier in the future.
- Also causes a lot of churn, helped along by some automated code
transformations
* add more core support for detecting (and "correcting") bitflips in erased
pages; requires opt-in by drivers, but at least we kill a few bad
implementations and hopefully stave off future ones
* pxa3xx_nand: cleanups, a few fixes, and PM improvements
* new JZ4780 NAND driver
SPI NOR
* provide default erase function, for controllers that just want to send the
SECTOR_ERASE command directly
* fix some module auto-loading issues with device tree ("jedec,spi-nor")
* error handling fixes
* new Mediatek QSPI flash driver
Other
* cfi: force valid geometry Kconfig (finally!)
- this one used to trip up randconfigs occasionally, since bots aren't
deterred by big scary "advanced configuration" menus
More? Probably. See the commit logs.

ARM: kill off set_irq_flags usage
set_irq_flags is ARM specific with custom flags which have genirq equivalents. Convert drivers to use the genirq interfaces directly, so we can kill off set_irq_flags. The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls. Some users also modify IRQ_NOPROBE and this has been maintained although it is not clear that is really needed. There appears to be a great deal of blind copy and paste of this code.

ARM: Show proper respect for Heinrich Hertz by using the correct unit for frequency
The SI unit of frequency is Hertz, named after Heinrich Hertz, and is given the symbol "Hz" to denote this. "hz" is not the unit of frequency, and is in fact meaningless. Fix arch/arm to correctly use "Hz", thereby acknowledging Heinrich Hertz' contribution to the modern world.

ARM: ixp4xx: fix {in,out}s{bwl} data types
Most platforms use void pointer arguments in these functions, but
ixp4xx does not, which triggers lots of warnings in device drivers like:
net/ethernet/8390/ne2k-pci.c: In function 'ne2k_pci_get_8390_hdr':
net/ethernet/8390/ne2k-pci.c:503:3: warning: passing argument 2 of 'insw' from incompatible pointer type
insw(NE_BASE + NE_DATAPORT, hdr, sizeof(struct e8390_pkt_hdr)>>1);
^
In file included from include/asm/io.h:214:0,
from /git/arm-soc/include/linux/io.h:22,
from /git/arm-soc/include/linux/pci.h:31,
from net/ethernet/8390/ne2k-pci.c:48:
mach-ixp4xx/include/mach/io.h:316:91: note: expected 'u16 *' but argument is of type 'struct e8390_pkt_hdr *'
static inline void insw(u32 io_addr, u16 *vaddr, u32 count)
Fixing the drivers seems hopeless, so this changes the ixp4xx code
to do the same as the others to avoid the warnings.

ARM: SoC: cleanups for 3.15
These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.
Notable changes are:
* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used. (Uwe Kleine-König)
* The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions. (Kumar Gala)
* A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
* Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
* mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
* at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people).

IXP4xx: Fix DMA masks.
Now, devices will have 32-bit default DMA masks (0xFFFFFFFF) as per DMA API. Fixes: $ ifconfig eth0 up net eth0: coherent DMA mask is unset $ ifconfig hdlc0 up net hdlc0: coherent DMA mask is unset Also fixes a cosmetic off-by-one bug which caused DMA transfers ending exactly on the 64 MiB boundary to go through dmabounce unnecessarily.

ARM: ixp4xx: avoid use of PCIBIOS_MIN_MEM in io.h
When using CONFIG_IXP4XX_INDIRECT_PCI, we run into a recursive
header file dependency between mach/io.h and asm/pci.h, resulting
in a build failure:
mach-ixp4xx/include/mach/io.h: In function 'is_pci_memory':
mach-ixp4xx/include/mach/io.h:53:18: error: 'PCIBIOS_MIN_MEM' undeclared (first use in this function)
return (addr >= PCIBIOS_MIN_MEM) && (addr <= 0x4FFFFFFF);
^
mach-ixp4xx/include/mach/io.h:53:18: note: each undeclared identifier is reported only once for each function it appears in
We can work around this by referencing the pcibios_min_mem variable
directly through an extern declaration, rather than using the macro.

ARM: SoC platform changes for 3.14
New core SoC-specific changes.
New platforms:
* Introduction of a vendor, Hisilicon, and one of their SoCs with some
random numerical product name.
* Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m, i.e. !MMU).
* Marvell Berlin series of SoCs, which include the one in Chromecast.
* MOXA platform support, ARM9-based platform used mostly in industrial products
* Support for Freescale's i.MX50 SoC.
Other work:
* Renesas work for new platforms and drivers, and conversion over to
more multiplatform-friendly device registration schemes.
* SMP support for Allwinner sunxi platforms.
* ... plus a bunch of other stuff across various platforms.
