Thanks for the confirmation.  I had a quick look at the 'git log' of the
relevant files and didn't see anything obvious.  When I get a chance I add
some debugging and see what is happening.

Again - thanks for confirming :-)  I thought I noticed that too but wasn't
really sure and forgot to mention it.
The earlier kernel show that same message so I don't think it is directly
related.  There were a number of changes in the DPI code which I didn't
understand, so I just copied the corresponding changes from other panel
devices.  I guess I need to look at those more carefully.

Thanks for noting that - it shouldn't be hard to work out why and find a way
to turn in on/off.

That's good.  I'm getting terrible power usage at the moment and don't really
know why.  Maybe I'm leaving something on which I shouldn't.  Glad to know it
isn't a core kernel problem.

Is this that GTA04a4?  I don't think I have the patch to support
hardware-routing in there.  Software routing works for me.

I should look at the hardware-routing patch.  I seem to recall there was
something about the design that I thought could be improved - but never got
further.

And thank you so much for testing.  It is both helpful and encouraging.
I'm flat-out this week but hope to find a slab of time next week to address
these issues and more.
