[PATCH v5 00/11] staging: iio: ad7780: move out of staging

[Renato Lui Geh]

This series of patches contains the following:
- Adds user input for the 'gain' and 'filter' GPIO pins for the ad778x
  family chips;
- Missing switch default case tidy up;
- Gain reading for the ad778x;
- Filter reading for the ad778x;
- Sets pattern macro values and mask for PATTERN status bits;
- Adds ID values for the ad7170, ad7171, ad7780 and ad7781 for ID
  status bits checking;
- Moves regulator initialization to after GPIO init to maintain
  consistency between probe and remove;
- Copyright edits, adding SPDX identifier and new copyright holder;
- Moves the ad7780 driver out of staging to the mainline;
- Adds device tree binding for the ad7780 driver.

Changelog:
*v3
- SPDX and regulator init as patches
- Renamed filter to odr and ad778x_filter to ad778x_odr_avail
- Removed unnecessary regulator disabling
- Removed unnecessary AD_SD_CHANNEL macro
- Changed unsigned int to unsigned long long to avoid overflow
*v4
- Split gain & filter patch into two, with the new commit adding only
  filter reading
- Changed pattern values to direct values, and added pattern mask
- Added ID values and mask
- Added new copyright holder
- Added device tree binding to the ad7780 driver
*v5
- Tidy ups
- Gain reading split from "gain & filter gpio support" commit to its
  own separate patch
- ad778x_odr_avail moved to more appropriate patch
- Init GPIOs in a separate function
- Raise error when ad717x tries to perform a write operation
