iio: ad9523: fix a missing check of return value

2019-01-05T16:10:50Z

If ad9523_write() fails, indio_dev may get incorrect data. The fix inserts a check for the return value of ad9523_write(), and it fails, returns an error. Signed-off-by: Kangjie Lu Signed-off-by: Jonathan Cameron

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

2018-09-02T17:54:31Z

In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier. Cc: Jonathan Cameron Cc: Hartmut Knaack Cc: Lars-Peter Clausen Cc: linux-iio@vger.kernel.org Signed-off-by: Rob Herring Signed-off-by: Jonathan Cameron

iio: ad9523: support for external signals via gpios

2018-07-28T09:41:14Z

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()

2018-07-28T09:35:34Z

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

2018-07-24T17:17:08Z

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

2018-07-23T18:18:11Z

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

2017-08-22T20:28:20Z

The equivalent is now done via macro magic when the relevant register call is made. The actual structure element will shortly go away. Signed-off-by: Jonathan Cameron Reviewed-by: Lars-Peter Clausen
