Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

I couldn't really find a way to implement per-transfer overrides for the
word size because the controller simply has no concept of word sizes.
Is it
in such cases still necessary to hardwire the word size

Yes, it is.
Its summary says Variable length of transfer word up to 32 bits;
does that mean configurable when core is synthesized instead of
to compute the
clock divider.

This patch adds a platform device driver that supports the OpenCores SPI
controller.
The driver expects two resources: an IORESOURCE_MEM resource defining the
core's memory-mapped registers and an IORESOURCE_IRQ for the associated
interrupt. It also requires a clock

This second version is pretty much a rewrite.
That happens sometimes...
Some notes about the most
important changes:
* uses per-chip states to allow more slaves to use the controller
concurrently
to compute the
clock divider.
