* iio: adf4350: Convert to use GPIO descriptorLinus Walleij2019-12-151-4/+0
| | | | | | | | | | | | The lock detect GPIO line is better to grab using a GPIO descriptor. We drop the pdata for this: clients using board files can use machine descriptor tables to pass this GPIO from static data.

* treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 177Thomas Gleixner2019-05-301-2/+1
| | | | | | | | | | | | | | | | | | | | | Based on 1 normalized pattern(s): licensed under the gpl 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 135 file(s).

* iio: frequency: ADF4350: Fix potential reference div factor overflow.Michael Hennerich2012-08-161-0/+2
| | | | | | | | | | | | With small channel spacing values and high reference frequencies it is possible to exceed the range of the 10-bit counter. Workaround by checking the range and widening some constrains. We don't use the REG1_PHASE value in this case the datasheet recommends to set it to 1 if not used.
