I am looking at the PMU datasheet, and I just want to verify Your information.
In PCF50633 at page 14 (page 119 in PCF50633 user manual), accsw is
connected to adcin1 with a 100k resistor and adcin is connected to gnd
with Racc. Is the information I got from You correct?
I will look at the current kernel driver to see how it is implemented, but I
assume ratiometric measurement is used (ref. PCD50633 user manual
@ page 102).
Please don't send me Word or PowerPoint attachments. See
