Looks good. But I will not merge it without a user and have comments
for the driver.
Android has been looking for these properties for a while now [1].
It was added[2] when we saw that the manufacturers were implementing these
properties in the driver. I didn't know the properties were absent upstream
until yesterday. Somebody pointed out in our ongoing effort to make sure
all core kernel changes that android depends on are present upstream.

I think those values are also propagated in application facing APIs in
Android (but I am not sure yet, let me know if that's something you want
to find out).

I wanted to chime in and present you a 'user' for this if that helps.

We have re-submitted the BQ25150/155 driver that would be the user and we have 2 more for review that will use the new definitions
