* powerpc: add mmc-spi-slot bindingsAnton Vorontsov2009-04-01
| | | | | | | | | | | | | | | | The bindings describes a case where MMC/SD/SDIO slot directly connected to a SPI bus. Such setups are widely used on embedded PowerPC boards. The patch also adds the mmc-spi-slot entry to the OpenFirmware modalias table.

| * gianfar: Fix stashing supportAndy Fleming2009-02-04
| | | | | | | | | | | | | | | | | | | | Stashing is only supported on the 85xx (e500-based) SoCs. The 83xx and 86xx chips don't have a proper cache for this. U-Boot has been updated to add stashing properties to the device tree nodes of gianfar devices on 85xx. So now we modify Linux to keep stashing off unless those properties are there.

* | powerpc: add fsl,fifo-depth property to Freescale SSI device nodesTimur Tabi2009-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale Serial Synchronous Interface (SSI) is an audio device present on some Freescale SOCs. Various implementations of the SSI have a different transmit and receive FIFO depth, but are otherwise identical. To support these variations, add a new property fsl,fifo-depth to the SSI node that specifies the depth of the FIFOs. Also update the MPC8610 HPCD device tree with this property.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ndfc driver only compiles under arch/ppc. This arch was removed from the kernel. I notice the event entry for the ndfc in Kconfig has been removed in 2.6.28. This patch converts the ndfc to a proper OF (OpenFirmware) driver. I can give a working example of the DTS if needed. The patch has been in production use on the PIKA Warp Appliance and is in use by others. The Warp basically boots from NAND, so the ndfc driver is very important to us.

| | | | | | | | | | | | | | | | | | Commit d0fc2eaaf4c56a95f5ed29b6bfb609e19714fc16 "powerpc/fsl: Refactor device bindings" split out a number of device bindings from booting-without-of.txt into separate files. Having them all in one file was a frequent source of merge conflicts. However, in the next merge, 49997d75152b3d23c53b0fa730599f2f74c92c65, there was another conflict. Some of the bindings removed from booting-without-of.txt were mistakenly added back in and the copies in dts-bindings were kept as well. This patch re-removes "Freescale Display Interface" and "Freescale on board FPGA" and fixes the table of contents.

Second is the config base, this is new. This is documented in dts-bindings/fsl/83xx-512x-pci.txt The changes accomplish these things: mpc83xx_add_bridge no longer needs to call get_immrbase it uses hard coded addresses if the second register value is missing Signed-off-by: John Rigby <jrigby@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
