This is the first NFC pull request for 4.5 and it brings:
- A new driver for the STMicroelectronics ST95HF NFC chipset.
The ST95HF is an NFC digital transceiver with an embedded analog
front-end and as such relies on the Linux NFC digital
implementation. This is the 3rd user of the NFC digital stack.
- ACPI support for the ST st-nci and st21nfca drivers.
- A small improvement for the nfcsim driver, as we can now tune
the Rx delay through sysfs.
- A bunch of minor cleanups and small fixes from Christophe Ricard,
for a few drivers and the NFC core code.

A ton of improvements to dwc2 have been made. The
driver should be a lot more stable on v4.5 then ever
before.
Our good old dwc3 got a few cleanups and misc fixes
and also added support to Xilinx's integration of

Yoshihiro Shimoda gives us support for a new USB3
peripheral controller from Renesas.
Other than these, the usual misc fixes all over the

As of commit 3d7608e4c1 ("ARM: shmobile: bockw: remove legacy
board file and config"), the Renesas R-Car (Gen1) USB PHY driver is no
longer used.
In theory it could still be used on R-Car Gen1 SoCs, but that would
require adding DT support to the driver. Instead, a new driver using the
generic PHY framework should be written, as was done for R-Car Gen2.
Remove the driver for good.

The old ADC and touchscreen drivers are not compatible with
multiplatform support, but we can use the exynos-adc driver
as a replacement.
This changes the common device creation functions for s3c64xx
(but not s3c24xx for now) to use the new driver. To do this,
we have to pass the interrupt resources in the opposite order
and pass the platform data in the adc device node.

As we are now passing the filter data as pointers to the drivers,
we can take the final step and also pass the filter function the
same way. I'm keeping this change separate, as there it's less
obvious that this is a net win.
Upsides of this are:
- The ASoC drivers are completely independent from the DMA engine
implementation, which simplifies the Kconfig logic and in theory
allows the same sound drivers to be built in a kernel that supports
different kinds of dmaengine drivers.
- Consistency with other subsystems and drivers
On the other hand, we have a few downsides:
- The s3c24xx-dma driver now needs to be built-in for the ac97 platform
device to be instantiated on s3c2440.
- samsung_dmaengine_pcm_config cannot be marked 'const' any more
because the filter function pointer needs to be set at runtime.
This is safe as long we don't have multiple different DMA engines
in thet same system at runtime, but is nonetheless ugly.

ARM64 allmodconfig produces a bunch of warnings when building the
samsung ASoC code:
sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data':
sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
playback_data->filter_data = (void *)playback->channel;
sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
capture_data->filter_data = (void *)capture->channel;
We could easily shut up the warning by adding an intermediate cast,
but there is a bigger underlying problem: The use of IORESOURCE_DMA
to pass data from platform code to device drivers is dubious to start
with, as what we really want is a pointer that can be passed into
a filter function.
Note that on s3c64xx, the pl08x DMA data is already a pointer, but
gets cast to resource_size_t so we can pass it as a resource, and it
then gets converted back to a pointer. In contrast, the data we pass
for s3c24xx is an index into a device specific table, and we artificially
convert that into a pointer for the filter function.

Let's not mix platform_data headers with the core headers. Instead, let's
create a subdir at linux/platform_data and move the headers to that
common place, adding it to MAINTAINERS.
The headers were moved with:
mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/

for i in $DIRS; do
for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do

This patch adds device tree support for the netxbig LEDs.
This also introduces a additionnal DT binding for the GPIO extension bus
(netxbig-gpio-ext) used to configure the LEDs. Since this bus could also
be used to control other devices, then it seems more suitable to have it
in a separate DT binding.

This is the NFC pull request for 4.4.
It's a bit bigger than usual, the 3 main culprits being:
- A new driver for Intel's Fields Peak NCI chipset. In order to
support this chipset we had to export a few NCI routines and
extend the driver NCI ops to not only support proprietary
commands but also core ones.
- Support for vendor commands for both STM drivers, st-nci
and st21nfca. Those vendor commands allow to run factory tests
through the NFC netlink interface.
- New i2c and SPI support for the Marvell driver, together with
firmware download support for this driver's core.
Besides that we also have:
- A few file renames in the STM drivers, to keep the naming
consistent between drivers.
- Some improvements and fixes on the NCI HCI layer, mostly to
properly reach a secure element over a legacy HCI link.
- A few fixes for the s3fwrn5 and trf7970a drivers.

In order to align with st21nfca, dts configuration properties
ese_present and uicc_present are made available in st-nci driver.
So far, in early development firmware, because
nci_nfcee_mode_set(DISABLE) was not supported we had to try to
enable it during the secure element discovery phase.
After several trials on commercial and qualified firmware it appears
that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
properly supported.
Such feature also help us to eventually save some time (~5ms) when
only one secure element is connected.

With the old binding and driver architecture we had many issues:
No way to assign eDMA channels to event queues, thus not able to tune the
system by moving specific DMA channels to low/high priority servicing. We
moved the cyclic channels to high priority within the code, but that was
just a workaround to this issue.
Memcopy was fundamentally broken: even if the driver scanned the DT/devices
in the booted system for direct DMA users (which is not effective when the
events are going through a crossbar) and created a map of 'used' channels,
this information was not really usable. Since via dmaengien API the eDMA
driver will be called with _some_ channel number, we would try to request
this channel when any channel is requested for memcpy. By luck we got
channel which is not used by any device most of the time so things worked,
but if a device would have been using the given channel, but not requested
it, the memcpy channel would have been waiting for HW event.
The old code had the am33xx/am43xx DMA event router handling embedded. This
should have been done in a separate driver since it is not part of the
actual eDMA IP.
There were no way to 'lock' PaRAM slots to be used by the DSP for example
when booting with DT.
In DT boot the edma node used more than one hwmod which is not a good
practice and the kernel prints warning because of this.
With the new bindings and the changes in the driver we can:
- No regression with Legacy binding and non DT boot
- DMA channels can be assigned to any TC (to set priority)
- PaRAM slots can be reserved for other cores to use
- Dynamic power management for CC and TCs, if only TC0 is used all other TC
can be powered down for example

We no longer have users for these functions so they can be removed.
Remove also unused enums from the header file.

struct at91_can_data was used to pass a callback to the driver, allowing it
to switch the transceiver on and off. As all at91 boards are now using DT,
this is not used anymore, remove that structure.

Move ATMEL_MAX_UART from platform_data/atmel.h to atmel_serial.c as this is
the only file using it and it is common practise from tty/serial drivers to
define it directly in the driver file.

struct at91_udc_data is now only used inside the driver, move it to its

this driver has long ago became dwc2.ko with
both peripheral and host roles, there's no point
in keeping the old function names.

include/linux/platform_data/atmel.h has a lot of useless includes, remove
