iio: Convert to using %pOFn instead of device_node.name

2018-09-02T17:54:31+00:00

In preparation to remove the node name pointer from struct device_node,
convert printf users to use the %pOFn format specifier.

iio: ad9523: support for external signals via gpios

2018-07-28T09:41:14+00:00

The AD9523 supports external signals for power-down mode, resetting the
device and sync timing.
This change add support for specifying values for these signals via the
gpios and initializing them default values.

For the reset signal, the GPIO is toggled during probing to re-initialize
the device to a known state.

iio: ad9523: Fix return value for ad952x_store()

2018-07-28T09:35:34+00:00

A sysfs write callback function needs to either return the number of
consumed characters or an error.

The ad952x_store() function currently returns 0 if the input value was "0",
this will signal that no characters have been consumed and the function
will be called repeatedly in a loop indefinitely. Fix this by returning
number of supplied characters to indicate that the whole input string has
been consumed.

iio: ad9523: Fix displayed phase

2018-07-24T17:17:08+00:00

Fix the displayed phase for the ad9523 driver. Currently the most
significant decimal place is dropped and all other digits are shifted one
to the left. This is due to a multiplication by 10, which is not necessary,
so remove it.

iio: ad9523: replace core mlock with local lock

2018-07-23T18:18:11+00:00

This is also part of a long term effort to make the use of mlock opaque and
single purpose.

This lock is required for accessing device registers. The device may be
accessed by multiple processes at the same time, and this can result in
inconsistent data, where one device reads data before the other one has
finished writing.

iio:frequency: drop assign iio_info.driver_module

2017-08-22T20:28:20+00:00

The equivalent is now done via macro magic when
the relevant register call is made.  The actual structure
element will shortly go away.

Pull spi updates from Mark Brown:
 "Quite a lot of activity in SPI this cycle, almost all of it in drivers
  with a few minor improvements and tweaks in the core.

   - Updates to pxa2xx to support Intel Broxton and multiple chip selects.
   - Support for big endian in the bcm63xx driver.
   - Multiple slave support for the mt8173
   - New driver for the auxiliary SPI controller in bcm2835 SoCs.
