Thanks for the patch, I've looked briefly over it. Some questions/feedback:
Does this code drive the hostmot2 firmware module called "UART" in the
regmap? Or something else not mentioned in the cu

So far so good.
I decided that all the bits of magnetic grit were either in the oil,
in the oil filter, in the bottom of the sump or stuck somewhere out of
the way. I dropped the su

Surely what you are describing there is more related to the drive
Well, in precise machine control, there are systems which use SRM motors in
the range of 400V, 500A which offer phase accuracy of about 10um at speeds
of 10m/s.
Does that make them AC servo motors or BLDC motors?
And as for "flat-topped sine wave, are you sure it is NOT a space vector
wave? When I
