Jonathan writes:
First set of IIO new device support, features and cleanups in the 4.19 cycle
The usual mixed bunch. Particular good to see is the generic
touch screen driver. Will be interesting to see if this works
for other ADCs without major changes.
Core features
* Channel types
- New position relative channel type primarily for touch screen
sensors to feed the generic touchscreen driver.
New device support
* ad5586
- Add support for the AD5311R DAC.
* Generic touch screen driver as an IIO consumer.
- Note this is in input, but due to dependencies is coming through
the IIO tree.
- Specific support for this added to the at91-sama5d2 ADC.
- Various necessary DT bindings added.
Staging Drops
* ADIS16060 gyro
- A device with a very odd interface that was never cleanly supported.
It's now very difficult to get, so unlikely it'll ever be fixed up.
Cleanups and minor features and fixes
* core
- Fix y2038 timestamp issues now the core support is in place.
* 104-quad-8
- Provide some defines for magic numbers to help readability.
- Fix an off by one error in register selection
* ad7606
- Put in a missing function parameter name in a prototype.
* adis16023
- Use generic sign_extend function rather than local version.
* adis16240
- Use generic sign_extend funciton rather than local version.
* at91-sama5d2
- Drop dependency on HAS_DMA now this is handled elsewhere. Will
improve build test coverage.
- Add oversampling ratio control. Note there is a minor ABI change
here to increase the apparent depth to 14 bits so as to allow
for transparent provision of different oversampling ratios that
drop the actual bit depth to 13 or 12 bits.
* hx711
- Add a MAINTAINERS entry for this device.
* inv_mpu6050
- Replace the timestamp fifo 'special' code with generic timestamp
handling.
- Switch to using local store of timestamp divider rather than rate
as that is more helpful for accurate time measurement.
- Fix an unaligned access that didn't seem to be causing any trouble.
- Use the fifo overflow bit to track the overflow status rather than
a software counter.
- New timestamping mechanism to deal with missed sample interrupts.
* stm32-adc
- Drop HAS_DMA build dependency.
* sun4i-gpadc
- Select REGMAP_IRQ a very rarely hit build issue fix.

iio: adc: at91-sama5d2_adc: add support for oversampling resolution
This implements oversampling support for the SAMA5d2 ADC device.
Enabling oversampling : OSR can improve resolution from 12 bits to
13 or 14 bits.
Changing the channel specification to have 14 bits, and we shift the value
1 bit to the left if we have oversampling for just one extra bit, and two
bits to the left if we have no oversampling (old support).
From this commit on, the converted values for all the voltage channels
change to 14 bits real data, with most insignificant two bits always zero
if oversampling is not enabled.
sysfs object oversampling_ratio has been enabled and
oversampling_ratio_available will list possible values (1 or 4 or 16) having
1 as default (no oversampling, 1 sample for each conversion).
Special care was required for the triggered buffer scenario (+ DMA), to
adjust the values accordingly.
Touchscreen measurements supported by this driver are not affected by
oversampling, they are still on 12 bits (scale handing is already included
in the driver).

iio: adc: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

staging: mt7621-dts: correct various clock frequencies.
The MT7621 documentation says that the sys clock - also known
as OCP clock for the Open Core Protocol - can be configured to
1/3 or 1/4 of the CPU clock.
Testing on my hardware, using the fact that the SPI clock is
based on the OCP clock and measuring transfer rates, shows
a clock of a little over 200MHz with a CPU clock of 900MHz.
So assume 1/4 is the default.
Also, the nor-flash in the gbpc1 is documented as accepting 50MHz
for request requests, and higher for other requests. So set
maximum to 50MHz.

staging: mt7621-spi: revised half-duplex message handling
The mt7621 SPI engine has a 32 byte buffer and the driver
currently only allows 32-byte read requests and 36 bytes writes
(there is a 4byte op/addr buffer).
This is an unnecessary limitation. As the SPI clock is controlled
by the host it is quite acceptable to send a larger message in
multiple smaller transactions. As long as Chip Select is kept asserted
the whole time, the SPI engine can be run multiple times for
a single SPI message.
This patch factors out the transaction logic and calls for each
transfer in the message. A write transfer might leave bytes in the
buffer to be combined with a following read transfer, as this is
a common pattern.
With this in place, we can remove the current max_transfer_size limit.
In testing, this increases the read throughput for a NOR flash chip
from 1.4MB/s to 2.3MB/s, a 50% improvement.
