Cortex-A9 SoCs and actually enabling usb on the rk3066-marsboard,
Two more veyron-devices - namely Speedy and Minnie and a fix for
the tsadc.
One slightly more interesting fix is the blocking of the last
16MB of memory on 4GB rk3288 devices. The rk3288 cannot use this
area for dma operations, so things like the mmc or usb controllers
regularly fail when trying to read data. This solution mimicks the
solution from the ChromeOS kernel, who also do not seem to have
found a better solution yet. Here it only moves to the devicetree.
As this issue is also present on the arm64 rk3368, any future
better solution to this problem would need to describe this in
the devicetree as well and could then remove this block.

Take 2 also includes a fix set that was too late for the 4.2 cycle.
As we had a lot of tools and docs work in this set, I have broken those
out into their own categories in this description.
Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
* Poll functions for both event chardev and the buffer one were returning
negative error codes (via a positive value).
* A recent change to lsiio adding some error handling that was wrong and
stopped the tool working.
* bmg160 was missing some dependencies in Kconfig
* berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
New device support
* TI opt3001 light sensor
* TXC PA12 ALS and proximity sensor.
* mcp3301 ADC support (in mcp320x driver)
* ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
common support to allow different WHOAMI register addresses, devices with
fixed scale and allow interrupt equiped magnetometers).
* ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
* ADIS16266 gyro (in the adis16260 driver)
* ADIS16137 gyro (in the adis16136 driver)
New functionality
* mmc35240 DT bindings.
* Inverse unit conversion macros to aid handing of values written to sysfs
attributes.
Core cleanup
* Forward declaration of struct iio_trigger to avoid a compile warning.
Driver cleanup / fixes
* mxs-lradc
- Clarify which parts are supported.
- Fix spelling erorrs.
- Missing/extra includes
- reorder includes
- add datasheet name listings for all usable channels (to allow them
to be bound by name from consumer drivers)
* acpi-als - add some function prefixes as per general iio style.
* bmc150_magn - replace a magic value with the existing define.
* vf610 - determine possible sample frequencies taking into account the
electrical characteristics (defining a minimum sample time)
* dht11
- whitespace
- additional docs
- avoid mulitple assignments in one line
- Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
previously used for timing.
* Fix all drivers that consider 0 a valid IRQ for historical reasons.
* Export I2C module alias info where previously missing (to allow autoprobing)
* Export OF module alias info where previously missing.
* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
- expand area locked by a mutex to cover all the use of the
data->buffer.
- use descriptive naming for a mask instead of a magic value.
* berin2-adc
- pass up an error code rather that a generic error
- constify the iio_chan_spec
- some other little tidy ups.
* stk8312
- fix a dependency on triggered buffers in kconfig
- add a check for invalid attribute values
- improve error handling by returning error codes where possible and
return immediately where relevant
- rework macro defs to use GENMASK etc
- change some variable types to reduce unnecessary casting
- clean up code style
- drop a local buffer copy for bulk reads and use the one in data->buffer
instead.
* adis16400 - the adis16448 gyroscope scale was wrong.
* adis16480 - some more wrong scales for various parts.
* adis16300 - has an undocumented product id and serial number registers so
use them.
* iio_simple_dummy - fix some wrong code indentation.
* bmc150-accel - use the chip ID to detect the chip present rather than
verifying the expected part was there. This was in response to a wrong
ACPI entry on the WinBook TW100.
* mma8452
- fix _get_hp_filter_index
- drop a double include
- pass up an error code rather than rewriting it
- range check input values to attribute writes
- register defs tidy up using GENMASK and reordering them to be easier to
follow.
- various coding style cleanups
- put the Kconfig entry in the write place (alphabetically).
Tools related
* Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
them in the middle of normal output.
* Fix tools to allow that scale and offset attributes are optional.
* More tools fixes including allowing true 32bit data (previously an overflow
prevented more than 31bits)
* Drop a stray header guard that ended up in a c file.
* Make calc_digits static as it isn't exported or in the header.
* Set ci_array pointer to NULL after free as a protection against non safe
usage of the tools core code. Also convert a double pointer to a single
one as the extra level of indirection was unnecessary.
Docs
* DocBook introduction by Daniel Baluta. Glad we are beginning to
draw together some more introductory docs to suplement the various
tools / examples.
* Drop bytes_per_datum sysfs attribute docs as it no longer exists.
* A whole load of missing / fixing of kernel-doc for the core of IIO.
* Document the trigger name sysfs attribute in the ABI docs.
* Minor typos in the ABI docs related to power down modes.

LTC3882 is mostly compatible with LTC3880. Major differences are that it
does not measure the input current, and it no longer supports LTC's legacy
mechanism to identify the chip.

Add Clock Domain support to the R-Car M1A Clock Pulse Generator (CPG)
driver using the generic PM Domain. This allows to power-manage the
module clocks of SoC devices that are part of the CPG/MSTP Clock Domain
using Runtime PM, or for system suspend/resume.

for "cpus" directly under the root node, so this is a hard
convention. So move the CPU nodes.

As a prerequisite to exporting cpu_hotplug_enable/cpu_hotplug_disable
functions to modules we need to convert cpu_hotplug_disabled to a counter
to properly support disable -> disable -> enable call sequences. E.g.
after Hyper-V vmbus module (which is supposed to be the first user of
exported cpu_hotplug_enable/cpu_hotplug_disable) did cpu_hotplug_disable()
hibernate path calls disable_nonboot_cpus() and if we hit an error in
_cpu_down() enable_nonboot_cpus() will be called on the failure path (thus
making cpu_hotplug_disabled = 0 and leaving cpu hotplug in 'enabled'
state). Same problem is possible if more than 1 module use
cpu_hotplug_disable/cpu_hotplug_enable on their load/unload paths. When
one of these modules is been unloaded it is logical to leave cpu hotplug
in 'disabled' state.
To support the change we need to increse cpu_hotplug_disabled counter
in disable_nonboot_cpus() unconditionally as all users of
disable_nonboot_cpus() are supposed to do enable_nonboot_cpus() in case
an error was returned.

Linear charging does a good job with not-so-reliable power sources.
Auto mode does not work well as it switches off when voltage drops

It was used with a bike hub dynamo since a year or so. In that case
there are automatically charging stops when the cyclist needs a break.

It turns out that only Dell laptops have the separate button bits for
v2 dualpoint sticks and that commit 92bac83dd7 ("Input: alps - non
interleaved V2 dualpoint has separate stick button bits") causes
regressions on Toshiba laptops.
This commit adds a check for Dell laptops to the code for handling these
extra button bits, fixing this regression.
This patch has been tested on a Dell Latitude D620 to make sure that it
does not reintroduce the original problem.

However, the bulk of the series is localized to qla2xxx target

That said, I don't see a good reason to wait another month to get

- bugfix for a long standing use-after-free in iscsi-target during
TPG shutdown + demo-mode sessions.
- bugfix for a >= v4.0 regression OOPs in iscsi-target during a

Clock rates are stored in an unsigned long field, but ->determine_rate()
(which returns a rounded rate from a requested one) returns a long
value (errors are reported using negative error codes), which can lead
to long overflow if the clock rate exceed 2Ghz.
Change ->determine_rate() prototype to return 0 or an error code, and pass
a pointer to a clk_rate_request structure containing the expected target
rate and the rate constraints imposed by clk users.
The clk_rate_request structure might be extended in the future to contain
other kind of constraints like the rounding policy, the maximum clock
inaccuracy or other things that are not yet supported by the CCF
(power consumption constraints ?).

Merge tag 'mmc-4.2-rc3' of git://git.linaro.org/people/ulf.hansson/mmc
Pull MMC fixes from Ulf Hansson:
"Here are some mmc fixes intended for v4.2 rc4.
Note, most of the changes are for the sdhci-esdhc-imx controller,
which also required us to modify some related DTS files. Those
changes have been acked by the SoC maintainer.
MMC core:
- Fix a reference inbalance issue for power_ro_lock_show() sysfs handler
MMC host:
- omap_hsmmc: Fix IRQ errorhandling for CD, DTO, and CRC
- sdhci: Prevent a kernel panic while using DMA
- mtk-sd: Let it depend on HAS_DMA to prevent build errors
- sdhci-esdhc: Make 8BIT bus work
- sdhci-esdhc-imx: Fix some regressions for DT based platforms
- sdhci-pxav3: Fix a regression for DT based platforms"

Currently the pre-scaler limit is incorrect. The value differs slightly
for various devices so a single value can't be used. Using the compatible
field select the correct pre-scaler limit.
Add new compatible field value for Keystone devices to support their
unique pre-scaler limit value.

This patch adds a new DT property, "atmel,fifo-size", to enable and set
the maximum number of data the RX and TX FIFOs can store on FIFO capable
USARTs.
Please be aware that the VERSION register can not be used to guess the
size of FIFOs. Indeed, for a given hardware version, the USARTs can be
integrated on Atmel SoCs with different FIFO sizes. Also the
"atmel,fifo-size" property is optional as older USARTs don't embed FIFO at
all.
Besides, the FIFO size can not be read or guessed from other registers:
When designing the FIFO feature, no dedicated registers were added to
store this size. Unsed spaces in the I/O register range are limited and
better reserved for future usages. Instead, the FIFO size of each
peripheral is documented in the programmer datasheet.
Finally, on a given SoC, there can be several instances of USART with
different FIFO sizes. This explain why we'd rather use a dedicated DT
property than use the "compatible" property.

Due to Advisory 21 as documented in AM437x errata document,
UART module cannot be disabled once DMA is used. The only
workaround is to softreset the module before disabling it.
DRA7x UARTs are compatible to AM437x UARTs in terms of
this errata and prescribed workaround.
Enable usage of workaround for this errata on DRA7x SoCs.

Use of of_machine_is_compatible() for handling AM335x specific
"DMA kick" quirk in 8250_omap driver makes it ugly to extend the
quirk for other platforms. Instead use a new compatible.
The new compatible will also make it easier to take care of
other quirks on AM335x and like SoCs.
In order to not break backward DTB compatibility for users of
8250_omap driver on AM335x based boards, existing use of
of_machine_is_compatible() has not been removed.
