5fe23c7f51 sdhci: Add support for hosts that are only capable of 1-bit transfers
Some hosts (hardware configurations, or particular SD/MMC slots) may
not support 4-bit bus. For example, on MPC8569E-MDS boards we can
switch between serial (1-bit only) and nibble (4-bit) modes, thought
we have to disable more peripherals to work in 4-bit mode.

Along with some small core changes, this patch modifies sdhci-of
driver, so that now it looks for "sdhci,1-bit-only" property in the
device-tree, and if specified we enable a proper quirk.

d1a277c584 can: sja1000: generic OF platform bus driver
This patch adds a generic driver for SJA1000 chips on the OpenFirmware

  can@3,100 {
  	compatible = "nxp,sja1000";
  	reg = <3 0x100 0x80>;
  	interrupts = <2 0>;
  	interrupt-parent = <&mpic>;
  	nxp,external-clock-frequency = <16000000>;
  };

98ca77af23 powerpc/qe: update QE Serial Number
The latest QE chip may have more Serial Number(SNUM)s of thread to use. We
will get the number of SNUMs from device tree by reading the new property
"fsl,qe-num-snums", and set 28 as the default number of SNUMs so that it is
compatible with the old QE chips' device trees which don't have this new
property. The macro QE_NUM_OF_SNUM is defined as the maximum number in QE
snum table which is 256.

Also we update the snum_init[] array with 18 more new SNUMs which are
confirmed to be useful on new chip.

a7d878af94 leds: Add openfirmware platform device support
Add bindings to support LEDs defined as of_platform devices in addition to
the existing bindings for platform devices.

New options in Kconfig allow the platform binding code and/or the
of_platform code to be turned on.  The of_platform code is of course only
available on archs that have OF support.

The existing probe and remove methods are refactored to use new functions
create_gpio_led(), to create and register one led, and delete_gpio_led(),
to unregister and free one led.  The new probe and remove methods for the
of_platform driver can then share most of the common probe and remove code
with the platform driver.

The suspend and resume methods aren't shared, but they are very short.  The
actual led driving code is the same for LEDs created by either binding.

The OF bindings are based on patch by Anton Vorontsov
<avorontsov@ru.mvista.com>.  They have been extended to allow multiple LEDs
per device.

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 d0fc2eaaf4 "powerpc/fsl: Refactor

However, in the next merge, 49997d7515, 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

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

GTM stands for General-purpose Timers Module and able to generate
timer{1,2,3,4} interrupts. 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

9b53a9e28a fbdev: powerpc: driver for Freescale 8610 and 5121 DIU
The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIs

All /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0.  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. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.

If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

ecc6cd73b7 [POWERPC] Start removing linux,network-index in favour of aliases
This patch alters the bootwrapper for a number of machines (roubhly
all 4xx based cuboot or treeboot platforms) to use aliases instead of
the linux,network-index hack to work out which MAC address to attach
to which ethernet device node.

The now obsolete linux,network-index properties are removed from the
corresponding device trees.  This won't break backwards compatiblity,
because in cases where this fixup code is relevant, the device tree is
part of the kernel image.

The references to linux,network-index are removed from
booting-without-of.txt.  Not only is it now deprecated, but as a hack
applicable only when the device tree blob and fixup code were in the
same image, this property never belonged in booting-without-of.txt
which describes the interface between the kernel and firmware or
bootloaders which produce a device tree.  By the time the device tree
reaches the kernel, all the MAC addresses must be fully filled in.

5b14e5f9dd [POWERPC] #address-cells & #size-cells properties are not inherited
Fix error in booting-without-of.txt that indicates that a node can inherit
its #address-cells and #size-cells definitions from its parent's parent.
This is not correct.

253772b151 [POWERPC] booting-without-of: localbus should not include board name
Fix documentation once and for ever, because I'm pretty tired of
repeating that I am merely following it. ;-)

ab99eee8ac [POWERPC] Xilinx: Update booting-without-of.
This now better describes what the UBoot device tree generator
actually does.  In particular:

1) Nodes have a label derived from the device name, and a node name
derived from a generic version of the device type, e.g. 'ethernet',
'serial', etc.

2) Usage of compound nodes (representing more than one device in the
same IP) which actually works.  This requires having a valid
compatible node, and all the other things that a bus normally has.
I've chosen 'xlnx,compound' as the bus name to describe these compound
nodes.

In addition, I've clarified some of the language relating to how mhs
nodes should be represent in the device tree.

174b0da231 [POWERPC] qe: add function qe_clock_source()
Add function qe_clock_source() which takes a string containing the name of a
QE clock source (as is typically found in device trees) and returns the
matching enum qe_clock value.

Update booting-without-of.txt to indicate that the UCC properties rx-clock
and tx-clock are deprecated and replaced with rx-clock-name and tx-clock-name,
which use strings instead of numbers to indicate QE clock sources.

e77b28eb19 [POWERPC] FSL: enet device tree cleanups
* Removed address fields in ethernet nodes
* Removed #address-cells, #size-cells from gianfar nodes
* Added cell-index to gianfar and ucc ethernet nodes
* Added enet[0..3] labels
* Renamed compatible node for gianfar mdio to "fsl,gianfar-mdio"
* Removed device_type = "mdio"

The matching for gianfar mdio still supports the old "mdio"/"gianfar" combo
but it is now considered deprecated.
