iio: potentiometer: mcp4131: use of_device_get_match_data()

2018-11-16T18:32:35+00:00

Try to get the device's data using OF API. In case of failure, fallback to the spi_get_device_id() method. Signed-off-by: Slawomir Stepien Signed-off-by: Jonathan Cameron

iio: potentiometer: tpl0102: add IIO_AVAIL_RANGE support

2018-11-11T15:29:45+00:00

Report the step range of the respective potentiometers that are possible to userspace. Signed-off-by: Matt Ranostay Signed-off-by: Jonathan Cameron

iio: potentiometer: tpl0102: switch to using pointer to chip config

2018-11-11T15:29:42+00:00

More concise to have a pointer to tpl0102_cfg struct in the iio_priv data than an integer to an index of an array. Signed-off-by: Matt Ranostay Reviewed-by: Slawomir Stepien Signed-off-by: Jonathan Cameron

iio: potentiometer: merge calls to of_match_device and of_device_get_match_data

2018-08-19T19:16:39+00:00

Drop call to of_match_device, which is subsumed by the subsequent call to of_device_get_match_data. The code becomes simpler, and a temporary variable can be dropped. The semantic match that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r@ local idexpression match; identifier i; expression x, dev, e, e1; @@ - match@i = of_match_device(x, dev); - if (match) e = of_device_get_match_data(dev); - else e = e1; + e = of_device_get_match_data(dev); + if (!e) e = e1; @@ identifier r.i; @@ - const struct of_device_id *i; ... when != i // Signed-off-by: Julia Lawall Reviewed-by: Peter Rosin Signed-off-by: Jonathan Cameron
