(documentation of the device tree bindings for the Freescale SSI device).

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.

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.

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.

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.

Does the same for the accompanying MDIO driver, and then modifies the TBI
configuration method. The old way used fields in einfo, which no longer
exists. The new way is to create an MDIO device-tree node for each instance
of gianfar, and create a tbi-handle property to associate ethernet controllers
with the TBI PHYs they are connected to.

We don't want to encourage the bogus device_type usage.
The device type isn't used in the code, so we can simply remove it from
the documentation and dts files.
Boards should specify proper compatible entries instead.

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. When a property is marked as such, the Elo
DMA driver will ignore it, and so it will be available for the sound drivers.

Modify mpc83xx_add_bridge to get config space register base address from
the device tree instead of immr + hardcoded offset.
83xx pci nodes have this change:
register properties now contain two address length tuples:
First is the pci bridge register base, this has always been there.
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

MPC8610 HPCD device tree. These properties connect the SSI nodes to the
DMA nodes for the DMA channels that the SSI should use. Also update the

This patch replaces the get_mctrl/set_mctrl stubs with modem control line
read/write access through the GPIO lib.
Available modem control lines are described in the device tree using GPIO
bindings. The driver expect a GPIO pin for each of the CTS, RTS, DCD, DSR,
DTR and RI signals. Unused control lines can be left out.
