From: Axel Haslam <ahaslam@xxxxxxxxxxxx> These patches aim to improve on the ad5791 driver: - make use of chip_info / match tables, and drop device enum id. - Add reset, clr and ldac gpios that have to be set to the correct level in case they are not hardwired on the setup/PCB. - simplify probe by using the devm_* functions to automatically free resources. --- Changes in v3: - v2 is missing the version prefix. Im sending v3 just with the added review-by tag. - Add review-by tag from David Lechner - Link to V2: https://lore.kernel.org/all/94a03835-bdd1-4243-88c7-0ad85784fe36@xxxxxxxxxxxx/ Changes in v2: - Fix probe error print using uninitialized ret. - Add documentation for new struct parameters - Add review-by tags to device tree bindings - Link to V1: https://lore.kernel.org/all/CAKXjFTPwN2TYW6sq1kj3miZ0f5OqKX0aTk8eGf1sj9TBk1_e=A@xxxxxxxxxxxxxx/T/ Axel Haslam (6): dt-bindings: iio: dac: ad5791: Add optional reset, clr and ldac gpios dt-bindings: iio: dac: ad5791: Add required voltage supplies iio: dac: ad5791: Include chip_info in device match tables iio: dac: ad5791: Add reset, clr and ldac gpios iio: dac: ad5791: Use devm_regulator_get_enable_read_voltage iio: dac: ad5791: Use devm_iio_device_register .../bindings/iio/dac/adi,ad5791.yaml | 39 ++++ drivers/iio/dac/ad5791.c | 203 ++++++++---------- 2 files changed, 131 insertions(+), 111 deletions(-) -- 2.34.1
