Albrecht Dreß 0c2daaafcd powerpc/5200/i2c: improve i2c bus error recovery
This patch improves the recovery of the MPC's I2C bus from errors like bus
hangs resulting in timeouts:
1. make the bus timeout configurable, as it depends on the bus clock and
    the attached slave chip(s); default is still 1 second;
2. detect any of the cases indicated by the CF, BB and RXAK MSR flags if a
    timeout occurs, and add a missing (required) MAL reset;
3. use a more reliable method to fixup the bus if a hang has been detected.
    The sequence is sent 9 times which seems to be necessary if a slave
    "misses" more than one clock cycle.  For 400 kHz bus speed, the fixup is
    also ~70us (81us vs. 150us) faster.

Tested on a custom Lite5200b derived board, with a Dallas RTC, AD sensors
and NXP IO expander chips attached to the i2c.

Changes vs. v1:
- use improved bus fixup sequence for all chips (not only the 5200)
- calculate real clock from defaults if no clock is given in the device tree
- better description (I hope) of the changes.

I didn't split the changes in this file into three parts as recommended by
Grant, as they actually belong together (i.e. they address one single
problem, just in three places of one single source file).

Anatolij Gustschin 8b856f040c powerpc/fsl-diu-fb: Support setting display mode using EDID
Adds support for encoding display mode information
in the device tree using verbatim EDID block.

If the EDID entry in the DIU node is present, the
driver will build mode database using EDID data
and allow setting the display modes from this database.
Otherwise display mode will be set using mode
entries from driver's internal database as usual.

This patch also updates device tree bindings.

Ira Snyder d3f620b2c4 fsldma: simplify IRQ probing and handling
The IRQ probing is needlessly complex. All off the 83xx device trees in
arch/powerpc/boot/dts/ specify 5 interrupts per DMA controller: one for the
controller, and one for each channel. These interrupts are all attached to
the same IRQ line.

This causes an interesting situation if two channels interrupt at the same
time. The per-controller handler will handle the first channel, and the
per-channel handler will handle the remaining channels.

Instead of this mess, we fix the bug in the per-controller handler, and
make it handle all channels that generated an interrupt. When a
per-controller handler is specified in the device tree, we prefer to use
the shared handler instead of the per-channel handler.

The 85xx/86xx controllers do not have a per-controller interrupt, and
instead use a per-channel interrupt. This behavior has not been changed.

This patch adds needed nodes and properties to support suspend/resume

There is a dedicated switch (SW9) that is used to wake up the boards.
By default the SW9 button is routed to IRQ8, but could be re-routed
(via PIXIS) to sreset.

With 'no_console_suspend' kernel command line argument specified, the
board is also able to wakeup upon serial port input.

Anton Vorontsov 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.

Grant Likely 34df9f69a4 powerpc/5200: update device tree binding documentation
This patch updates the mpc5200 binding documentation to match
actual usage conventions, to remove incorrect information, and
to remove topics which are more thoroughly described elsewhere.

Anton Vorontsov 94409d6e10 powerpc: Add device tree bindings for BCSR GPIO banks
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.

Andy Fleming b31a1d8b41 gianfar: Convert gianfar to an of_platform_driver
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.

Anton Vorontsov fd657efc67 powerpc: Remove device_type = "board_control" properties in .dts files
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.

Timur Tabi b56c2768d2 powerpc: document the "fsl,ssi-dma-channel" compatible property
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.

John Rigby 5b70a09705 powerpc: 83xx: pci: Remove need for get_immrbase from mpc83xx_add_bridge.
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
