In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
C code changes for SoC platforms. This release cycle the diffstat is quite
nice, in that we're removing 3x the amount of code that's being added.
The main reason for this is that there's a removal of camera drivers for
Freescale i.MX chips (driver was removed so the device registration isn't
needed any more). There's also removal of display initialization code for OMAP
that is no longer needed.
The rest are mostly minor tweaks and cleanups; constification on Samsung
platforms, cleanup of ux500 platform data, purge of other unused platform
data/device seutp on i.MX and other good stuff.
New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

These are updates for platform specific code on 32-bit ARM machines,
essentially anything that can not (yet) be expressed using DT files.
Noteworthy changes include:
- Added support for the TI DRA71x family of SoCs in mach-omap2,
this is an new variant of the the DRA72x/DRA74x automotive
infotainment chips we already supported for a while.
- Added support for the ST STM32F746 SoC, the first Cortex-M7
based microcontroller we support, related to the smaller
STM32F4 family.
- Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
see http://elinux.org/RZ-G
- SMP is now supported on the OX820 platform
- A lot of code in mach-omap2 gets removed as a follow-up to
removing support for board files in the previous release
- Davinci has some new work to improve USB support
- For i.MX, the performance monitor now supports profiling the
memory controller using 'perf'

Instead of having the smc91x driver relying on machine_is_*() calls,
provide this data through platform data, ie. idp, mainstone and

This way, the driver doesn't need anymore machine_is_*() calls, which
wouldn't work anymore with a device-tree build.

The method to acquire the input interrupt was working in a platform data
based board, but was failing in a device-tree one when the gpio
controller was probed after pxa_cplds.
Use platform_get_irq() to benefit from the probe deferral
mechanism. Moreover, as seen in dm9000.c development, platform_get_irq()
doesn't honor the irq type IO resource (ie. edge rising for example),
and it must be passed again at irq request in a not device-tree build,
hence the irq_get_trigger_type() call.

- The recently added Uniphier platform now uses standard PSCI
methods for SMP booting and we remove support for old bootloader
versions that did not support it yet.
- In sunxi, we gain support for the "Nextthing GR8" SoC, which

Subsystem improvements:
- Do away with the last users of the obsolete Kconfig options
ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
always sounded like an item on a wishlist to Santa Claus to
me). We can now select GPIOLIB and be done with it, for all
archs. After some struggle it even work on UM. Not that it has
GPIO, but if it wants to, it can select the library.
- Continued efforts to make drivers properly either tristate or
bool.
- Introduce a warning for drivers assigning default triggers to
their irqchip lines when probed from device tree, so we find and
fix these ambigous drivers. It is agreed that in the OF config
path, the device tree defines trigger characteristics.
- The same warning, mutatis mutandis, for ACPI-probed GPIO
irqchips.
- We introduce the ability to mark certain IRQ lines as "unusable"
as they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is
put to good use in the STMPE driver and also in the Cherryview
pin control driver.
- A new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM
with allyesconfig or allmodconfig it exploded in their face.
- Move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so
now eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- New driver for the Aspeed GPIO front-end companion to the
pin controller merged through the pin control tree.
- New driver for the LP873x PMIC GPIO portions.
- New driver for Technologic Systems' I2C FPGA GPIO such as
TS4900, TS-7970, TS-7990 and TS-4100.
- New driver for the Broadcom BCM63xx series including BCM6338
and BCM6345.
- New driver for the Intel WhiskeyCove PMIC GPIO.
- New driver for the Allwinner AXP209 PMIC GPIO portions.
- New driver for Diamond Systems 48 line GPIO-MM, another of
these port-mapped I/O expansion cards.
- Support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- The STMPE driver now supports rising/falling edge detection
properly for IRQs.
- The PCA954x will now fetch and enable its VCC regulator properly.
- Major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- Switch the IOP driver to use the generic MMIO GPIO library.
- Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns.

they can be taken by BIOS/firmware, unrouted in silicon and
generally nasty if you use them, and such things. This is put to
good use in the STMPE driver and also in the Cherryview pin control
driver.
- a new "mockup" virtual GPIO device that can be used for testing.
The plan is to add unit tests under tools/* for exercising this
device and verify that the kernel code paths are working as they
should.
- make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
implicit all the time, but when people started building UM with
allyesconfig or allmodconfig it exploded in their face.
- move some stray bits of device tree and ACPI HW description
callbacks down into their respective implementation silo. These
were causing issues when compiling on !HAS_IOMEM as well, so now
eventually UM compiles the GPIOLIB library if it wants to.
New drivers:
- new driver for the Aspeed GPIO front-end companion to the pin
controller merged through the pin control tree.
- new driver for the LP873x PMIC GPIO portions.
- new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
TS-7970, TS-7990 and TS-4100.
- new driver for the Broadcom BCM63xx series including BCM6338 and
BCM6345.
- new driver for the Intel WhiskeyCove PMIC GPIO.
- new driver for the Allwinner AXP209 PMIC GPIO portions.
- new driver for Diamond Systems 48 line GPIO-MM, another of these
port-mapped I/O expansion cards.
- support the STMicroelectronics STMPE1600 variant in the STMPE
driver.
Driver improvements:
- the STMPE driver now supports rising/falling edge detection
properly for IRQs.
- the PCA954x will now fetch and enable its VCC regulator properly.
- major rework of the PCA953x driver with the goal of eventually
switching it over to use regmap and thus modernize it even more.
- switch the IOP driver to use the generic MMIO GPIO library.
- move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
over to this subsystem from MFD, achieveing some separation of
concerns"

Add the required PCMCIA clock for the SA1111 "1800" device. This clock
is used to compute timing information for the PCMCIA interface in the
SoC device, rather than the SA1111. Hence, the provision of this clock
is a convenience for the driver and does not reflect the hardware, so
this must not be copied into DT.

Since its initial commit, the driver is buggy for multiple interrupts
handling. The translation from the former lubbock.c file was not
complete, and might stall all interrupt handling when multiple
interrupts occur.
This is especially true when inside the interrupt handler and if a new
interrupt comes and is not handled, leaving the output line still held,
and not creating a transition as the GPIO block behind would expect to
trigger another cplds_irq_handler() call.
For the record, the hardware is working as follows.
The interrupt mechanism relies on :
- one status register
- one mask register
Let's suppose the input irq lines are called :
- i_sa1111
- i_lan91x
- i_mmc_cd
Let's suppose the status register for each irq line is called :
- status_sa1111
- status_lan91x
- status_mmc_cd
Let's suppose the interrupt mask for each irq line is called :
- irqen_sa1111
- irqen_lan91x
- irqen_mmc_cd
Let's suppose the output irq line, connected to GPIO0 is called :
- o_gpio0
The behavior is as follows :
- o_gpio0 = not((status_sa1111 & irqen_sa1111) |
(status_lan91x & irqen_lan91x) |
(status_mmc_cd & irqen_mmc_cd))
=> this is a N-to-1 NOR gate and multiple AND gates
- irqen_* is exactly as programmed by a write to the FPGA
- status_* behavior is governed by a bi-stable D flip-flop
=> on next FPGA clock :
- if i_xxx is high, status_xxx becomes 1
- if i_xxx is low, status_xxx remains as it is
- if software sets status_xxx to 0, the D flip-flop is reset
=> status_xxx becomes 0
=> on next FPGA clock cycle, if i_xxx is high, status_xxx becomes
1 again

The commit 9bf448c66d ("ARM: pxa: use generic gpio operation instead of
gpio register") from Oct 17, 2011, leads to the following static checker
warning:
arch/arm/mach-pxa/spitz_pm.c:172 spitz_charger_wakeup()
warn: double left shift '!gpio_get_value(SPITZ_GPIO_KEY_INT)
<< (1 << ((SPITZ_GPIO_KEY_INT) & 31))'
As Dan reported, the value is shifted three times :
- once by gpio_get_value(), which returns either 0 or BIT(gpio)
- once by the shift operation '<<'
- a last time by GPIO_bit(gpio) which is BIT(gpio)
Therefore the calculation lead to a chained or operator of :
- (1 << gpio) << (1 << gpio) = (2^gpio)^gpio = 2 ^ (gpio * gpio)
It is be sheer luck the former statement works, only because each gpio
used is strictly smaller than 6, and therefore 2^(gpio^2) never
overflows a 32 bits value, and because it is used as a boolean value to
check a gpio activation.
As the xxx_charger_wakeup() functions are used as a true/false detection
mechanism, take that opportunity to change their prototypes from integer
return value to boolean one.

Commit b70661c708 ("net: smc91x: use run-time configuration on all ARM
machines") broke some ARM platforms through several mistakes. Firstly,
the access size must correspond to the following rule:
(a) at least one of 16-bit or 8-bit access size must be supported
(b) 32-bit accesses are optional, and may be enabled in addition to
the above.
Secondly, it provides no emulation of 16-bit accesses, instead blindly
making 16-bit accesses even when the platform specifies that only 8-bit
is supported.
Reorganise smc91x.h so we can make use of the existing 16-bit access
emulation already provided - if 16-bit accesses are supported, use
16-bit accesses directly, otherwise if 8-bit accesses are supported,
use the provided 16-bit access emulation. If neither, BUG(). This
exactly reflects the driver behaviour prior to the commit being fixed.
Since the conversion incorrectly cut down the available access sizes on
several platforms, we also need to go through every platform and fix up
the overly-restrictive access size: Arnd assumed that if a platform can
perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
size needed to be specified - not so, all available access sizes must
be specified.
This likely fixes some performance regressions in doing this: if a
platform does not support 8-bit accesses, 8-bit accesses have been
emulated by performing a 16-bit read-modify-write access.
Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
accesses, which was broken by the original commit.

A couple of bug fixes have come in for v4.8 so far. Since the first few were
originally meant to go into -rc1 (but didn't get sent in time for travel
reasons), the branch is unfortunately based on top of a commit in the
middle of the merge window rather than -rc1.
Content-wise we have
- A fix for the last remaining broken build in kernelci,
getting mach-shmobile to build again with SMP disabled
- A fix for a realview regression that broke real hardware but
not the qemu model that everyone uses in practice (needed
for v4.7 as well)
- A merge conflict fix for Tegra that also broke v4.7
- Two Kconfig fixes for arm64 build regressions
- A couple of arm32 build warning fixes (all harmless)
- Fixing the RTC on Exynos7 Espresso (which apparently
never worked right)

First cycle with Boris as NAND maintainer! Many (most) bullets stolen from him.
Generic:
* Migrated NAND LED trigger to be a generic MTD trigger
NAND:
* Introduction of the "ECC algorithm" concept, to avoid overloading the ECC
mode field too much more
* Replaced the nand_ecclayout infrastructure with something a little more
flexible (finally!) and future proof
* Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some of
this into their own tree as well
* Prepare the sunxi NAND driver to receive DMA support
* Handle bitflips in erased pages on GPMI revisions that do not support
this in hardware.
SPI NOR:
* Start using the spi_flash_read() API for SPI drivers that support it (i.e.,
SPI drivers with special memory-mapped flash modes)
And other small scattered improvments.

Pincontrol is not yet ready for all PXA platforms.
For example, a legacy platform, if PINCTRL was activated, will fail its
calls to gpio_request() or gpio_direction_output(), as the pinctrl
driver might not be available, such as for pxa25x and pxa3xx.
As a step forward, activate pincontrol for all device-tree available
machines, ie. pxa27x device-tree based and pxa3xx device-tree based.
If it appears later that pincontrol is also required for legacy
platforms and if the mfp->pinctrl conversion can be achieved, then
PINCTRL will be activated for the whole PXA architecture.

Since device_add_property_set() now always takes a copy of
the property_set, and also since the fwnode type is always
hard coded to be FWNODE_PDATA, there is no need for the
drivers to deliver the entire struct property_set. The
function can just create the instance of it on its own and
bind the properties from the drivers to it on the spot.
This renames device_add_property_set() to
device_add_properties(). The function now takes struct
property_entry as its parameter instead of struct
property_set.

gcc-6.0 notices that the use of the property_entry in this file that
was recently introduced cannot work right, as we initialize the wrong
field:
raumfeld.c:387:3: error: the address of 'raumfeld_rotary_encoder_steps' will always evaluate as 'true' [-Werror=address]
DEV_PROP_U32, 1, &raumfeld_rotary_encoder_steps, },
^~~~~~~~~~~~
raumfeld.c:389:3: error: the address of 'raumfeld_rotary_encoder_axis' will always evaluate as 'true' [-Werror=address]
DEV_PROP_U32, 1, &raumfeld_rotary_encoder_axis, },
^~~~~~~~~~~~
raumfeld.c:391:3: error: the address of 'raumfeld_rotary_encoder_relative_axis' will always evaluate as 'true' [-Werror=address]
DEV_PROP_U32, 1, &raumfeld_rotary_encoder_relative_axis, },
^~~~~~~~~~~~
The problem appears to stem from relying on an old definition of
'struct property', but it has changed several times since the code
could have last been correct.
This changes the code to use the PROPERTY_ENTRY_INTEGER() macro instead,
which works fine for the current definition and is a safer way of doing
the initialization.

Merge with Linux 4.5 to get PROPERTY_ENTRY_INTEGER() that is needed to
fix pxa/raumfeld rotary encoder properties.
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 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.
