Begin to consolidate of_device.c This moves all the common parts for the Sparc, Sparc64 and PowerPC of_device.c files into drivers/of/device.c. Apart from the simple move, Sparc gains of_match_node() and a call to of_node_put in of_release_dev(). PowerPC gains better recovery if device_create_file() fails in of_device_register().

[POWERPC] OF helpers for the GPIO API This implements various helpers to support OF bindings for the GPIO LIB API. Previously this was PowerPC specific, but it seems this code isn't arch-dependent anyhow, so let's place it into of/. SPARC will not see this addition yet, real hardware seem to not use GPIOs at all. But this might change: http://www.leox.org/docs/faq_MLleon.html "16-bit I/O port" sounds promising. :-) Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>

gpiolib: allow user-selection This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.

[POWERPC] i2c: Fix build breakage introduced by OF helpers Fix build breakage introduced in commit "[POWERPC] i2c: OF helpers for the i2c API". If i2c-core is compiled as a module, the helper needs to be compiled as a module, as well. Rename i2c.c to of_i2c.c to avoid name space conflict.

spi: Add OF binding support for SPI busses This patch adds support for populating an SPI bus based on data in the OF device tree. This is useful for powerpc platforms which use the device tree instead of discrete code for describing platform layout. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
