2018-09-07regmap: split up regmap_config.use_single_rwDavid Frey3-11/+14
Split regmap_config.use_single_rw into use_single_read and use_single_write. This change enables drivers of devices which only support bulk operations in one direction to use the regmap_bulk_*() functions for both directions and have their bulk operation split into single operations only when necessary. Update all struct regmap_config instances where use_single_rw==true to instead set both use_single_read and use_single_write. No attempt was made to evaluate whether it is possible to set only one of use_single_read or use_single_write.

2018-09-02iio: dac: ad5758: Add support for hard resetStefan Popa1-2/+24
The ad5758 has a hardware reset active low input pin. This patch adds a devicetree entry for a reset GPIO and a new ad5758_reset() function. During initialization, it is checked if the reset property is specified and the the GPIO is being asserted, therefore the device will become active. When the reset function is called, if the gpio_reset var is set, then the GPIO will be toggled, otherwise a software reset is performed.
