Subject: [PATCH RFC 0/1] Convert mcp23s08 to DT usage

From: Lars Poeschel <poeschel@...onage.de>

I wanted to use mcp23s08 driver with a device that boots using device tree.
Therefore I had to modify the driver to be able to take it's platform_data
from the device tree.
I am using a mcp23017 (I2C) device successfully with the patch booted over
device tree. I am not sure if I did this right and I am not able to test the
SPI part of the driver, so I am requesting for comments.

Thank you,
Lars
