Cc: Ricardo Ribalda Delgado
Architectures based on device-tree does not have platform data
associated to the spi/i2c devices. Instead they can have some of
the options embedded in the device tree.
This patch allows the cma3000 driver to get the configuration
from the platform_data, the device tree, or in the wort case,
just use a default configuration.
v5: Fixes suggested by Grant Likely
-Device tree binding doc
-Use of_device_id table
v3: Fixes suggested by Jonathan Cameron
-Code style
-Add support for the device tree
v2: Fixes suggested by Jonathan Cameron
-Spelling
-Simplify pdata!=NULL check
