iio: adc: add a driver for the SAR ADC found in Amlogic Meson SoCs
This adds support for the SAR (Successive Approximation Register) ADC
on the Amlogic Meson SoCs.
The code is based on the public S805 (Meson8b) and S905 (GXBB)
datasheets (see [0] and [1]), as well as by reading (various versions
of) the vendor driver and by inspecting the registers on the vendor
kernels of my testing-hardware.
Currently the GXBB, GXL and GXM SoCs are supported. GXBB hardware has
10-bit ADC resolution, while GXL and GXM have 12-bit ADC resolution.
The code was written to support older SoCs (Meson8 and Meson8b) as well,
but due to lack of actual testing-hardware no of_device_id was added for
these.
Two "features" from the vendor driver are currently missing:
- the vendor driver uses channel #7 for calibration (this improves the
accuracy of the results - in my tests the results were less than 3%
off without calibration compared to the vendor driver). Adding support
for this should be easy, but is not required for most applications.
- channel #6 is connected to the SoCs internal temperature sensor.
Adding support for this is probably not so easy since (based on the
u-boot sources) most SoC versions are using different registers and
algorithms for the conversion from "ADC value" to temperature.
Supported by the hardware but currently not supported by the driver:
- reading multiple channels at the same time (the hardware has a FIFO
buffer which stores multiple results)
- continuous sampling (this would require a way to enable this
individually because otherwise the ADC would be drawing power
constantly)
- interrupt support (similar to the vendor driver this new driver is
polling the results. It is unclear if the IRQ-mode is supported on
older (Meson6 or Meson8) hardware as well or if there are any errata)

Busy looping for long periods is not just anti-social; udelay must not

integer overflow.

Timers IPs can be used to generate triggers for other IPs like
DAC or ADC.
Each trigger may result of timer internals signals like counter enable,
reset or edge, this configuration could be done through "master_mode"
device attribute.
Since triggers could be used by DAC or ADC their names are defined
in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger
function could be used to check if the trigger is valid or not.
"trgo" trigger have a "sampling_frequency" attribute which allow to configure
timer sampling frequency.
version 8:
- change kernel version from 4.10 to 4.11 in ABI documentation
version 7:
- remove all iio_device related code
- move driver into trigger directory
version 5:
- simplify tables of triggers
- only create an IIO device when needed
version 4:
- get triggers configuration from "reg" in DT
- add tables of triggers
- sampling frequency is enable/disable when writing in trigger
sampling_frequency attribute
- no more use of interruptions
version 3:
- change compatible to "st,stm32-timer-trigger"
- fix attributes access right
- use string instead of int for master_mode and slave_mode
- document device attributes in sysfs-bus-iio-timer-stm32

iio: accel: fix Kconfig warning
commit
762227721fe6225be5b6d233ef681aea5871f5f3
"iio: accel: st_accel: handle deprecated bindings"
attempted to be smart and let users use the old I2C
driver and the new SPI driver, or the old SPI driver and
the new I2C driver in combination for the LIS3LV02,
and put the restrictions on the I2C and SPI subdrivers
not not be combined with the old subdrivers.
This doesn't work since the IIO ST accel top-level
component selects the I2C and SPI subdrivers, resulting
in the following Kconfig noise:
warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C)
warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS
which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI
&& IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI)
(...)
This fixes the issue by putting the dependencies directly
in the top-level component instead, so that it never gets
to select its unselectable subcomponent.

iio: trigger: free trigger resource correctly
These stand-alone trigger drivers were using iio_trigger_put()
where they should have been using iio_trigger_free(). The
iio_trigger_put() adds a module_put which is bad since they
never did a module_get.
In the sysfs driver, module_get/put's are used as triggers are
added & removed. This extra module_put() occurs on an error path
in the probe routine (probably rare).
In the bfin-timer & interrupt trigger drivers, the module resources
are not explicitly managed, so it's doing a put on something that
was never get'd. It occurs on the probe error path and on the
remove path (not so rare).
Tested with the sysfs trigger driver.
The bfin & interrupt drivers were build tested & inspected only.

iio: trigger: close race condition in acquiring trigger reference
In iio_trigger_write_current() we find the trigger we want while
holding mutex on the list of triggers, but we don't actually do a
get on it while holding mutex. We wait until further validations
are completed and we're sure it's the one we want. Race condition
is that it could be freed by the time we do the get.
Solution is to grab the trigger (iio_trigger_get) as soon as we
find it while holding mutex on the list of triggers. If later
we decide it's not the right one, put it back. (iio_trigger_put).
