Subject: Re: [linux-sunxi] [PATCH 2/3] spidev: Add DT binding example.

Hi,

I've a feeling everyone in this thread is ignoring the
raspberry pi use-case. Where the board is specifically
designed for educational purposes and used with lots of
peripherals which are usually programmed from userspace
using e.g. python bindings for i2c-dev or spidev, for
such a setup we really want spidev to be loaded on the
spibus by default and we really do not have a proper
compatible for a child device.

And no having to use per device devicetree overlays
for this is not the answer, this needs to be really
really easy. With pre device-tree kernels this just
works, we should be able to match that ease of use
with devicetree.

Regards,

Hans
