RE: fpga driver on custom PPC target platform (P4080) ...

quoted

It appears that I'm not correctly creating the pca9539 nodes as of

yet (I'll be adding the phandles shortly). =A0Any pointers for pca9539
driver nodes would be appreciated, as I took these from a similar =

tree,

but not the 95xx driver. =A0I'll match them up with the code in the
morning ...

I *believe* you are not supposed to create separate nodes for reading
and writing.  I know that's how I2C works, but I think the I2C layer
takes care of that for you.

If you look at other device trees, you'll see they only have one node
for any particular I2C device.

Thanks, Timur ... I've fixed the tree, and I'm tracking down the =
problems with addressing the nodes ...
