2019-12-29iio: chemical: atlas-ph-sensor: rename atlas-ph-sensor to atlas-sensorMatt Ranostay1-684/+0
Since the orginal scope of the driver was to only support the pH product from Atlas it has evolved to other sensors. Rename the file, driver name, and regmap to atlas-sensor which reflects this, although keep CONFIG_ATLAS_PH_SENSOR to not cause regressions with current configurations.

2019-10-13iio: chemical: atlas-ph-sensor: fix iio_triggered_buffer_predisable() positionAlexandru Ardelean1-4/+4
The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. The iio_triggered_buffer_predisable() should be called last, to detach the poll func after the devices has been suspended. The position of iio_triggered_buffer_postenable() is correct. Note this is not stable material. It's a fix in the logical model rather fixing an actual bug. These are being tidied up throughout the subsystem to allow more substantial rework that was blocked by variations in how things were done.

2016-02-19iio: chemical: atlas-ph-sensor: switch regmap cacheMatt Ranostay1-3/+1
switch from using REGCACHE_FLAT to REGCACHE_RBTREE so initial hw values are read from device. This also allows some volatile ranges to be dropped. Note that REGCACHE_FLAT is intended only for very low lag cases so doesn't do nice things like read initial values from the device. Hence this change.
