Thank you very much for testing and for the detailed report. I'm very
glad it works on your Surface Laptop 1 too.

I'm now working on v2, which addresses Sakari's comments. In patch 2,
v2 will wait 8192 external clock cycles after power-on
instead of 20 ms, and request only the reset GPIO. The changes are
small, so I expect it to keep working, but the shorter delay applies to
your Surface as well.

I no longer have the NUC M15, as I have recently moved to a different
work laptop, so I can't test v2 on hardware myself and I'll say so in
the v2 cover letter. I would be very grateful if you could test v2 when
I send it. I'll Cc you on it.

Please send it as a separate patch, under your name. It doesn't depend
on this series (it applies to media next as it is), and the
SUBSCRIBE_EVENT failure is there without these patches as well.
