Yes, that is the only thing we have. Meaning that there is no hw setting to set the
pins to open drain. Open drain is what they are. That is why I'm not seeing the point
in having PIN_CONFIG_DRIVE_OPEN_DRAIN implemented.
At least you have to implement error for PUSH_PULL mode and other modes,
so from the (core) software point of view the user should be able to ask for
anything and get an answer from the certain driver that "hey, i do support OD",
or "hey, push-pull can't be supported with this hw".
It seems to me that this is heading towards a mfd driver. I don't feel comfortable
with all that gpio specific code in the hwmon subsystem.
Maybe I should request that all hwmon chips with gpio support must be implemented
as mfd drivers. I'll have to think about that.
Or auxiliary bus?
I don't know. All I can see it that it is getting way too complicated for a hwmon
driver with embedded gpio support.
