Atsushi Nemoto ba0a7f39ce spi: fix error paths on txx9spi_probe
Some error paths in txx9spi_probe wrongly return 0.  This patch fixes them by
using the devres interfaces.

Tony Jones 49dce689ad spi doesn't need class_device
Make the SPI framework and drivers stop using class_device.  Update docs
accordingly ...  highlighting just which sysfs paths should be
"safe"/stable.

Atsushi Nemoto 4ccdb4c872 spi: correct name for spi_txx9
Correct the name of the spi_txx9 driver (and their in-tree user)
instead of MODULE_ALIAS workaround.  This would be preferable in the
long term.

David Brownell fc3ba9525b SPI driver hotplug/coldplug fixes
Update various SPI drivers so they properly support

  - coldplug through "modprobe $(cat /sys/devices/.../modalias)"

  - hotplug through "modprobe $(MODALIAS)"

The basic rule for platform, SPI, and (new style) I2C drivers is just
to make sure that modprobing the driver name works.  In this case, all
the relevant drivers are platform drivers, and this patch either

  (a)	Changes the driver name, if no in-tree code would break;
	this is simpler and thus preferable in the long term.

  (b)	Adds MODULE_ALIAS directives, when in-tree platforms declare
	devices using the current driver name; less desirable.

Most systems will link SPI controller drivers statically, but
there's no point in being needlessly broken.

Atsushi Nemoto f2cac67dd3 spi_txx9 controller driver
This is a driver for SPI controller built into TXx9 MIPS SoCs.
This driver is derived from arch/mips/tx4938/toshiba_rbtx4938/spi_txx9.c.
