2009-02-04gianfar: Fix stashing supportAndy Fleming
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.

2009-01-05[MTD] [NAND] ndfc driverSean MacLennan
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.

2008-12-30powerpc: Add device tree bindings for BCSR GPIO banksAnton Vorontsov
The patch adds bindings for BCSR GPIO banks, the bindings are used to describe particular BCSR registers that act as simple GPIO controllers. These GPIO banks might control power switches, SPI chip-selects, LEDs, etc. While at it, also fix "length" spelling error in the PIXIS FPGA bindings.

2008-11-10powerpc: Repair device bindings documentationTrent Piepho
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.

The "fsl,ssi-dma-channel" compatible property is used to specify a DMA channel on the Freescale Elo DMA controller that should be used exclusively by the Freescale SSI audio controller.

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>

These timers are used by the drivers that need time precise interrupts (like for USB transactions scheduling for the Freescale USB Host controller as found in some QE and CPM chips), or these timers could be used as wakeup events from the CPU deep-sleep mode. Things unimplemented: 1. Cascaded (32 bit) timers (1-2, 3-4). This is straightforward to implement when needed, two timers should be marked as "requested" and configured as appropriate. 2. Super-cascaded (64 bit) timers (1-2-3-4). This is also straightforward to implement when needed, all timers should be marked as "requested" and configured as appropriate.

Changing pixel clock has no effect on other fbs. Limitation of usage of AOIs: AOIs on the same plane can not be horizonally overlapped AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1 AOIs can not beyond phisical display area. Application should check AOI geometry before changing physical resolution on /dev/fb0 required command line parameters to preallocate memory for frame buffer diufb. optional command line parameters to set modes and monitor video=fslfb:[resolution][,bpp][,monitor] Syntax: Resolution xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60 Bpp bpp=32, bpp=24, or bpp=16 Monitor monitor=0, monitor=1, monitor=2 0 is DVI 1 is Single link LVDS 2 is Double link LVDS Note: switching monitor is a board feather, not DIU feather.
