Merge branch 'spi/next' of git://git.secretlab.ca/git/linux-2.6
* 'spi/next' of git://git.secretlab.ca/git/linux-2.6: (34 commits) spi/dw_spi: move dw_spi.h into drivers/spi spi/dw_spi: Fix missing header gpio/langwell: Clear edge bit before handling gpio/langwell: Simplify demux loop gpio/langwell: Convert irq name space gpio/langwell: Fix broken irq_eoi change. gpio; Make Intel chipset gpio drivers depend on x86 gpio/cs5535-gpio: Fix section mismatch spi/rtc-{ds1390,ds3234,m41t94}: Use spi_get_drvdata() for SPI devices spi/davinci: Support DMA transfers larger than 65535 words spi/davinci: Use correct length parameter to dma_map_single calls gpio: Use __devexit at necessary places gpio: add MODULE_DEVICE_TABLE to pch_gpio and ml_ioh_gpio gpio/mcp23s08: support mcp23s17 variant of_mmc_spi: add card detect irq support spi/omap_mcspi: catch xfers of non-multiple SPI word size spi/omap_mcspi: Off-by-one error in finding the right divisor gpio/pca953x: Fix wrong pointer type spi/pl022: rid dangling labels spi: add support for SuperH SPI ...

+Required properties:
+- compatible : should be "opencores,tiny-spi-rtlsvn2".
+- gpios : should specify GPIOs used for chipselect.
+Optional properties:
+- clock-frequency : input clock frequency to the core.
+- baud-width: width, in bits, of the programmable divider used to scale
+ the input clock to SCLK.
+
+The clock-frequency and baud-width properties are needed only if the divider
+is programmable. They are not needed if the divider is fixed.
