* Freescale 83xx and 512x PCI bridges
Freescale 83xx and 512x SOCs include the same pci bridge core.
83xx/512x specific notes:
- reg: should contain two address length tuples
The first is for the internal pci bridge registers
The second is for the pci config space access registers

Note on DMA channel compatible properties: The compatible property must say
"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel" to be used by the Elo DMA
driver (fsldma). Any DMA channel used by fsldma cannot be used by another
DMA driver, such as the SSI sound drivers for the MPC8610. Therefore, any DMA
channel that should be used for another driver should not use
"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel". For the SSI drivers, for
example, the compatible property should be "fsl,ssi-dma-channel". See ssi.txt
for more information.

playback and DMA channel 3 for capture. The developer can choose which
DMA controller to use, but the channels themselves are hard-wired. The
purpose of these two properties is to represent this hardware design.
The device tree nodes for the DMA channels that are referenced by
"fsl,playback-dma" and "fsl,capture-dma" must be marked as compatible with
"fsl,ssi-dma-channel". The SOC-specific compatible string (e.g.
"fsl,mpc8610-dma-channel") can remain. If these nodes are left as
"fsl,elo-dma-channel" or "fsl,eloplus-dma-channel", then the generic Elo DMA
drivers (fsldma) will attempt to use them, and it will conflict with the
sound drivers.

* Interrupt Controller Handling
*
* The interrupt controller handles interrupts for most on board interrupts,
* apart from PCI interrupts. For example on SBC610:
*
* 17:31 RO Reserved
* 16 RO PCI Express Doorbell 3 Status
* 15 RO PCI Express Doorbell 2 Status
* 14 RO PCI Express Doorbell 1 Status
* 13 RO PCI Express Doorbell 0 Status
* 12 RO Real Time Clock Interrupt Status
* 11 RO Temperature Interrupt Status
* 10 RO Temperature Critical Interrupt Status
* 9 RO Ethernet PHY1 Interrupt Status
* 8 RO Ethernet PHY3 Interrupt Status
* 7 RO PEX8548 Interrupt Status
* 6 RO Reserved
* 5 RO Watchdog 0 Interrupt Status
* 4 RO Watchdog 1 Interrupt Status
* 3 RO AXIS Message FIFO A Interrupt Status
* 2 RO AXIS Message FIFO B Interrupt Status
* 1 RO AXIS Message FIFO C Interrupt Status
* 0 RO AXIS Message FIFO D Interrupt Status
*
* Interrupts can be forwarded to one of two output lines. Nothing
* clever is done, so if the masks are incorrectly set, a single input
* interrupt could generate interrupts on both output lines!
*
* The dual lines are there to allow the chained interrupts to be easily
* passed into two different cores. We currently do not use this functionality
* in this driver.
*
* Controller can also be configured to generate Machine checks (MCP), again on
* two lines, to be attached to two different cores. It is suggested that these
* should be masked out.

Say Y here to enable soft power-off functionality on the Freescale
boards with the MPC8349E-mITX-compatible MCU chips. This driver will
also register MCU GPIOs with the generic GPIO API, so you'll able
