pinctrl: sh-pfc: Updates for v4.13 (take two)
- Add SCIF1 and SCIF2 pin groups for R-Car V2H,
- Add EtherAVB, DU parallel RGB output, and PWM pin groups for R-Car
H3 ES2.0,
- Add pin and gpio controller support for RZ/A1.
Add output-enable generic pin configuration property.
This properties allows enabling/disabling pin's output capabilities
without actually driving any value on the line.

ALSA SoC needs to know connected DAI ID for probing. Using
the new audio-card-graph approach, ports/endpoints are used
to describe how the links are connected. Unfortunately, since
ports/endpoints are used as well for video linkages, there
are some issues mixing the port ids to the two (video and
audio) namespaces.
To solve this issue, this patch adds new .get_dai_id callback
on hdmi_codec_ops.
The will assume that HDMI audio out will be connected to
reg = <2>. This will then be remapped to the ALSA SoC side will
as DAI 0. Allowing the adv7511's hdmi audio support to be used
with the audio-card-graph.
Credit to Kuninori Morimoto who's patch to dw-hdmi-i2s-audio.c
was what this was mostly copy-pasted from.

Some LEDs can be related to a specific device(s) described in the DT.
This property allows specifying such relations. E.g. USB LED should
usually be used to indicate some USB port(s) state.
Please note this binding is designed to be generic and not influenced by
any operating system design. Linux developers may find "trigger" part a
bit confusing since in Linux triggers are separated drivers. It
shouldn't define the binding though (we shouldn't add an extra level of
indirection).

Second set of IIO new device support, features and cleanups for the 4.13 cycle.
A few reverts here. One was a general failure to notice a device was already
supported by another driver. The second is due to a review comment pointing
out that the original patch was a bad idea and would break existing systems.
Reverts
* bma180
- Revert addition of support for the BMA250E it is already supported by
the bmc150-accel and better supported at that. Oops.
* hi8435
- The fix for cleanup of the reset gpio stuff isn't a good way to go. It
breaks systems where an inverting level convertor is used. The right fix
is to make the original devicetree correct - even if it involves patching
the devicetree in kernel.
New Device Support
* stm32-adc
- STM32H7 support and bindings.
Features
* core
- add a hardware triggered operating mode for systems in which the actual
trigger is never seen by the kernel. This is typically only used when
a device 'can' use other triggers, but if a particular magic one is
enabled the interrupt is effectively handled in hardware and we never see
it.
* st-lsm6dsx
- support active low interrupts.
* stm32-adc
- Make the core adc clock optional as not all hardware supported requires it.
- Make the bus clock optional in the per instance driver as it may be shared
by all instances of the ADC and is handled by the core.
- Rework to have a data structure representing the device type specific
elements.
* stm32-trigger (and counter)
- Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate.
- Add an attribute to configure device modes for quadrature counting etc.
Clean ups and minor fixes
* IIO core.
- use __sysfs_match_string() helper rather than open coding the same.
* ad7791
- use sysfs_match_string() helper rather than open coding the same.
* aspeed-adc
- handle return value of clk_prepare_enable
* cpcap
- Fix default register values and ensure the battery thermistor is enabled
correctly.
- Fix the reported die temperature where we can - docs are lacking.
- Remove the hung interrupt quirk as no longer happens due to fix in the
mfd driver.
* hi8435
- Remove &s from hi8435_info definition as unneeded and inconsistent.
* hid-sensor-trgger
- Add kconfig depends on IIO_BUFFER (fixes patch in previous series)
* ina2xx
- Make the use of iio_info_mask* elements consistent for all channels.
This doesn't have any visible effect, but acts as clear documentation of
which channels various resulting attributes apply to.
* lpc32xx
- handle the return value of clk_prepare_enable.
* meson-saradc
- NULL instead of 0 for pointer.
* mma9551
- use NULL for GPIO connection ID to aid implementation fo ACPI support.
Here the connection ID doesn't actually tell us anything and it is much
easier to deal with the driver if it's not there.
* mpu6050
- Fix lock issues through use of a local mux.
- Replace sprintf with scnprintf as appropriate.
- Check whoami against all known values. This allows for a small number of
boards where we are really fishing for the part not being present at all.
It is unfortunately common to have undescribed changes to use newer chips.
We paper over this but just emitting a warning for those cases as long as
we know about.
* mxs-lradc
- Fix some non static warnings.
* rcar-adc
- Part of making the naming for this part consistent across the kernel.
* st_accel
- drop some spi_device_id entries for variants with no SPI support
* st_magn
- drop some spi_device_id entries for variants with no SPI support.
* sx9500
- Use devm_gpiod_get instead of indexed value with an index of 0 on all
occasions.
* twl4030
- Drop unused twl4030_get_madc_conversion as callers removed now throughout
kernel.
- Unexport twl4030_madc_conversion() as no used only within this driver.
- Drop twl4030_madc_user_params as not used now.
- Drop twl4030_madc_request.func_cb as not used now.
- Fold the twl4030-madc.h header into the driver as no longer used anywhere
else in the kernel.
* xilinx
- Handle the return value of clk_prepare_enable

wireless-drivers-next patches for 4.13
New features and bug fixes to quite a few different drivers, but
nothing really special standing out.
What makes me happy that we have now more vendors actively
contributing to upstream drivers. In this pull request we have patches
from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I
still have patches from Marvell and Quantenna pending in patchwork. Now
that's something comparing to how things looked 11 years ago in Jeff
Garzik's "State of the Union: Wireless" email:
https://lkml.org/lkml/2006/1/5/671
Major changes:
wil6210
* add low level RF sector interface via nl80211 vendor commands
* add module parameter ftm_mode to load separate firmware for factory
testing
* support devices with different PCIe bar size
* add support for PCIe D3hot in system suspend
* remove ioctl interface which should not be in a wireless driver
ath10k
* go back to using dma_alloc_coherent() for firmware scratch memory
* add per chain RSSI reporting
brcmfmac
* add support multi-scheduled scan
* add scheduled scan support for specified BSSIDs
* add support for brcm43430 revision 0
wlcore
* add wil1285 compatible
rsi
* add RS9113 USB support
iwlwifi
* FW API documentation improvements (for tools and htmldoc)

This reverts commit ab714817d7.
The original commit was designed to handle a bug in the trf7970a NFC
controller where an extra byte was returned in Read Multiple Blocks (RMB)
command responses. However, it has become less clear whether it is a bug
in the trf7970a or in the tag. In addition, it was assumed that the extra
byte was always returned but it turns out that is not always the case. The
result is that a byte of good data is trimmed off when the extra byte is
not present ultimately causing the neard deamon to fail the read.
Since the trf7970a driver does not have the context to know when to trim
the byte or not, remove the code from the trf7970a driver all together
(and move it up to the neard daemon). This has the added benefit of
simplifying the kernel driver and putting the extra complexity into
userspace.

The A31 and later have an R_INTC block which handles the NMI interrupt
pin on the SoC. This interrupt pin is used by the external PMIC to
signal interrupts to the SoC.
While this hardware block is undocumented, the interrupt offsets
combined with the register regions for the existing "sun6i-a31-sc-nmi"
compatible line up with the old interrupt controller found on the A10.
Experiments show that only the first 32 interrupt lines can be enabled,
and only the first (NMI) interrupt is actually connected.
This patch adds a new, properly named compatible for the A31 R_INTC
block, which requires the register region to be properly aligned to
the block boundary. For comparison, the old "sun6i-a31-sc-nmi"
compatible had its register region aligned with the first used
register. This didn't match up with the memory map in the SoC's
datasheet/user manual.
Since the new compatible supercedes the old one, deprecate the old one.
