 Move all the platform data to devicetree.

Nice! :)

 The only bit dropped is the PWM beeper, which requires the PWM 
driver
 to be updated. I figured it's okay to remove it here since it's 
really
 a non-critical device, and it'll be re-introduced soon enough.

OK, I can see that being a price worth paying. Though it's possible to
include the binding at least for that in this series I'd be even
happier. Actually I see we already have

  Documentation/devicetree/bindings/pwm/ingenic,jz47xx-pwm.txt

in mainline - what needs to change with it?

The PWM driver will be updated to use the TCU clocks and the regmap 
provided
by the TCU driver. The PWM node will be a sub-node of the TCU one.

Additionally, there is this[1] ongoing discussion about PWM which makes
me uneasy about how to write the binding. So I'd rather not rush it,
because once the devicetree is written, it's ABI.

Should this be "ilitek,ili8960"?

Is there a binding & driver for this submitted somewhere? If not then 
do
we need this at all? It doesn't look like the existing platform data
would actually lead to a driver being loaded so I'm wondering if we 
can
just drop this until such a driver (or at least a documented DT 
binding)
exists.

I can drop it. There is no driver for it, and I'm not even sure the LB60
has a ILI8960 in the first place.

Thanks,
    Paul
