If you don't do it, the bus number will be a bogus value, possibly used
for device file names in drivers like spidev.

Do you see any problem with that? Here is the take from Grant.

This patchset adds SPI master support for Freescale i.MX233/i.MX28.
This is rebased on top of next-20120713. Please consider applying,
bugs shall now be squashed during the previous two review rounds.

mmc: spi: Move SSP register definitions into separate file
mmc: spi:
Move the definitions into separate file so separate SPI driver can be
implemented. The SSP controller in MXS can act both as a MMC host and
as a SPI host.

This is slightly reworked version of the SPI driver.
Support for DT has been added and it's been converted
to queued API.

Since the SSP controller can act as both SPI and MMC host,
renaming the enum to properly reflect the naming seems
appropriate.

Add missing register bits and registers into mxs-spi.h .
These will be used by the SPI driver.

Pull out the MMC clock configuration function and make it
into SSP clock configuration function, so it can be used by
the SPI driver too.
