Hello,
I'm working with a board that uses LM25066s with sense resistor values
significantly different than the 1mOhm assumed by the coefficients
provided in the datasheet; the power and current readings produced by
the existing driver are thus fairly inaccurate.
This patch series started out as merely adding support for a
shunt-resistor-micro-ohms DT property as found in the adm1275 driver,
but along the way I noticed a number of other minor bits in the
lm25066 driver that looked like they could use some fixes, so I've
included those as well.
Patches 1 and 2 bring the m/b/R coefficients in line with what's in
the relevant datasheets, patches 3 through 5 are fairly generic
(minor) code cleanups, and patches 6 through 8 add the desired OF
support for the driver.
Thanks,
Zev
