747de77cd5 Provide public declarations for ofw_spibus_driver and ofw_spibus_devclass
so other drivers can refer to them in DRIVER_MODULE() decls.

7073d12c4d ofw_spi: Parse property for the SPI mode and CS polarity.
As cs is stored in a uint32_t, use the last bit to store the
active high flag as it's unlikely that we will have that much CS.

f3e8760ff5 [spibus] add initial placeholders for transfer mode and frequency.
This doesn't yet implement it in the controllers or the transfer
calls, but it's a start.

Obtained from:	loos (frequency), ray/zrouter (transfer mode)

585300e937 Add an OFW SPI compatible bus. Fix the spibus probe to return
BUS_PROBE_GENERIC and not BUS_PROBE_SPECIFIC (0) so the OFW SPI bus can
attach when enabled.  Export the spibus devclass_t and driver_t
declarations.

75da3c1a9b Replace inline static' by static inline'.
If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.

9a795dfa02 MFp4:
Initial spibus support.  Seems to be OK, but needs some polish.

	# someone should write a bit-bang spi parallel port interface :-)
