The Integrator/AP and Integrator/CP core modules have special
versions of the ICST525 interface hardcoding some bits. Create
special compatible strings to identify these variants, also
explain a bit what is going on.

The TX settings can be calibrated for particular hardware. The
phy is reset by Linux, so this cannot be handled by the bootloader.
The TRM mentions that the maximum resistance should be used for the
DN/DP calibration in order to pass USB certification.
The values for the TX registers are poorly described in the TRM.
The meanings of the register values were taken from another
NXP-provided document:

Support to configure the UTMI+ PHY with an 8- or 16-bit
interface via DT. The UTMI+ PHY interface is a hardware
capability, and it's platform dependent. Normally, the
PHYIF can be configured during coreconsultant.
But for some specific USB cores(e.g. rk3399 SoC DWC3),
the default PHYIF configuration value is false, so we
need to reconfigure it by software.

This patch enables getting a HPD GPIO descriptor quicker.
The exynos-hdmi driver uses "hpd" for HDMI hot plug detection.
static int hdmi_resources_init(struct hdmi_context *hdata)
{
...
hdata->hpd_gpio = devm_gpiod_get(dev, "hpd", GPIOD_IN);
...
}
This calls 'of_find_gpio()' and it generates the GPIO consumer ID by referring
GPIO suffix. So 'hpd-gpios' is preferred on getting a GPIO descriptor.
However, if the device tree uses 'hpd-gpio', then the exynos-hdmi driver
always retries to get a GPIO descriptor because the first GPIO suffix is not
'gpio' but 'gpios'. So you always see the debug message below.
of_get_named_gpiod_flags: can't parse 'hpd-gpios' property of node '/soc/hdmi@14530000[0]'
Use the preferred property, 'hpd-gpios' instead of 'hpd-gpio'.

rcar-card used specific property, not "simple-audio-card",

but noone is using it on upstream. The user is only local,

rsrc-card has board specific compatible (= lager/koelsh), but these were

Now normal user can use generic compatible (= renesas,rsrc-card).

First round of new features, device support and cleanups for IIO in the 4.9 cycle.
Device support
* ak8974
- New driver and bindings for this 2009 vintage magnetometer (it was very
popular back then!)
* atlas-ph-sensor
- ORP sensor support(I had to look up what one of these was)
* cio-dac
- New driver for Measurement Computing DAC boards
* dmard06
- New driver for Domintech DMARDO6 accelerometer. Also vendor prefix.
* dmard09
- New driver for Domintech DMARD09 accelerometer.
* maxim-thermocouple
- max6675 and max31855 new driver
* mt6577 auxdac
- new driver for this Mediatek chip mt2701, mt6577 and mt8173 have this
hardware.
* ti-adc161s626
- new driver for this TI single channel differential ADC.
* vcnl4000
- support vcnl4010 and vcnl4020 which are compatible for all features
currently supported by this driver.
New features
* Core
- Allow retrieving of underlying iio_dev from a callback buffer handle.
This is needed to allow client drivers to perform operations such as
configuring the trigger used.
* hid-sensors
- asynchronous resume support to avoid really long resume times.
* kxcjk-1013
- add the mysterious KIOX000A ACPI id seen in the wild.
* Tools
- lsiio now enumerates processed as well as raw channels.
Cleanup
* ad7298
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ad7793
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* ade7854
- checkpatch fixups (alignment of parameters)
* atlas-ph-sensor
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
- Switch to REGCACHE_NONE as there are no useful register to cache.
* bma180
- use iio_device_claim_direct_mode and friends to simplify locking around
mode switching and drop some boilerplate.
* hdc100x
- Add mention of the HDC1000 and HDC1008 to the Kconfig help text.
* isl29018
- Add driver specific prefixes to defines and function names.
- Remove excessive logging.
- Drop newlines which add nothing to readability.
- General tidying up of comments.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* isl29028
- Add driver specific prefixes to defines, enums and function names.
- Drop comma's from available attribute output as not ABI compliant.
- Drop I2C_CLASS_HWMON as irrelevant to driver.
* kxsd9
- devicetree bindings.
* mag3110
- This one wasn't locking to protect against mode switches during
raw_reads. Use the iio_claim_direct_mode function to fix this buglet.
* maxim-theromcouple
- Fix missing selects for triggered buffer support in Kconfig.
* nau7802
- Use complete instead of complete_all as only one completion at a time.
* sx9500
- Use complete instead of complete_all as only one completion at a time.
* us5182d
- Add a missing error code asignment instead of checking the result of
an already checked statement.
* vcnl4000
- Use BIT macro where appropriate.
- Refactor return codes in read_raw callback.
- Add some missing locking for concurrent accesses to the device.
Reorder the compatible vop devices to be sorted by chip number
in ascending order.

The new(ish) ft6236 simply re-implements the M09 protocol of the

This commit removes this duplicate driver and adds the i2c ids and
dt compatible string to the edt-ft5x06.c driver to keep compatibility.
This commit also adds the standard touchscreen properties as optional
properties to the edt,ft5x06 binding, these were documented in the
focaltech,ft6236 bindingi, but were missing from the edt,ft5x06 doc.
