Regulator: drivers that need to know their supply

2016-04-07 Thread Martin Fuzzey
Hi, I am working on a driver for the tps22993 load switch. This chip has configurable slew rates but no voltage setting (as it's just a switch). To implement the .enable_time() method I need the voltage (which is the supply's voltage). The problem is that, when my regulator is configured as
