f87ccd2edc dts: mpc512x: add clock related device tree specs
this addresses the clock driver aka provider's side of clocks
- introduce a 'clocks' subtree with an 'osc' node for the crystal
  or oscillator SoC input (fixed frequency)
- the 'clock@f00' clock-control-module node references the 'osc' for
  its input, and is another provider for all the clocks which the
  CCM component manages
- prepare for future references to clocks from peripheral nodes
  by means of the <&clks ID> syntax and symbolic ID names which a
  header file provides
- provide default values with 33MHz oscillator frequency in the
  common include (the 66MHz IPS bus already was there), and add
  override values for the ifm AC14xx board which deviates from
  the reference design (25MHz xtal, 80MHz IPS bus)

11daf32be9 powerpc/512x: dts: disable MPC5125 usb module
At the moment the USB controller's pin muxing is not setup
correctly and causes a kernel panic upon system startup, so
disable the USB1 device tree node in the MPC5125 tower board
dts file.

The USB controller is connected to an USB3320 ULPI transceiver
and the device tree should receive an update to reflect correct
dependencies and required initialization data before the USB1
node can get re-enabled.

bbca4d3917 powerpc/512x: dts: remove misplaced IRQ spec from 'soc' node (5125)
the 'soc' node in the MPC5125 "tower" board .dts has an '#interrupt-cells'
property although this node is not an interrupt controller

remove this erroneously placed property because starting with v3.13-rc1
lookup and resolution of 'interrupts' specs for peripherals gets misled
(tries to use the 'soc' as the interrupt parent which fails), emits
'no irq domain found' WARN() messages and breaks the boot process

[ best viewed with 'git diff -U5' to have DT node names in the context ]

Pull slave-dmaengine changes from Vinod Koul:
 "This brings for slave dmaengine:

   - Change dma notification flag to DMA_COMPLETE from DMA_SUCCESS as
     dmaengine can only transfer and not verify validaty of dma
     transfers

   - Bunch of fixes across drivers:

      - cppi41 driver fixes from Daniel

      - 8 channel freescale dma engine support and updated bindings from
        Hongbo

      - msx-dma fixes and cleanup by Markus

   - DMAengine updates from Dan:

      - Bartlomiej and Dan finalized a rework of the dma address unmap
        implementation.

      - In the course of testing 1/ a collection of enhancements to
        dmatest fell out.  Notably basic performance statistics, and
        fixed / enhanced test control through new module parameters
        'run', 'wait', 'noverify', and 'verbose'.  Thanks to Andriy and
        Linus [Walleij] for their review.

      - Testing the raid related corner cases of 1/ triggered bugs in
        the recently added 16-source operation support in the ioatdma
        driver.

      - Some minor fixes / cleanups to mv_xor and ioatdma"

8c43d2b0ca powerpc: Add T4 LAC device tree binding & defs
The Interlaken is a narrow, high speed channelized chip-to-chip interface. To
facilitate interoperability between a data path device and a look-aside
co-processor, the Interlaken Look-Aside protocol is defined for short
transaction-related transfers. Although based on the Interlaken protocol,
Interlaken Look-Aside is not directly compatible with Interlaken and can be
considered a different operation mode.

The Interlaken LA controller connects internal platform to Interlaken serial
interface. It accepts LA command through software portals, which are system
memory mapped 4KB spaces. The LA commands are then translated into the
Interlaken control words and data words, which are sent on TX side to TCAM
through SerDes lanes.

ab9a4183fd powerpc: Update currituck pci/usb fixup for new board revision
The currituck board uses a different IRQ for the pci usb host
controller depending on the board revision. This patch adds support
for newer board revisions by retrieving the board revision from the
FPGA and mapping the appropriate IRQ.

173192958d MMC highlights for 3.10:
Core:
  - Introduce MMC_CAP2_NO_PRESCAN_POWERUP to allow skipping mmc_power_up()
    at boot/initialization time if it's already happened, for performance
    (faster boot time) reasons.
  - Fix a bit width test failure that resulted in old eMMC cards being put
    into 1-bit mode when 4-bit mode was available.
  - Expose fwrev/hwrev for MMCv4 parts.
  - Improve card removal logic in the case where the card's removed slowly;
    we were missing card removal events if the card retained contact with
    the slot pads for long enough to reply to a CMD13 while being removed.
 
 Drivers:
  - davinci_mmc: Support using PIO instead of DMA.
  - dw_mmc: Add support for Exynos4412.
  - mxcmmc: DT support, use slot-gpio API.
  - mxs-mmc: Add broken-cd/cd-inverted/non-removable DT property support.
  - sdhci-sirf: New sdhci-pltfm driver for CSR SiRF SoCs:
     SiRFprimaII: unicore ARM Cortex-A9
     SiRFatlas6: unicore ARM Cortex-A9
     SiRFmarco: dual core ARM Cortex-A9 SMP
  - sdhci-tegra: Add support for Tegra114 platforms, use mmc_of_parse().

9e2ecdbba3 powerpc/fsl-booke: add the reg prop for pci bridge device node for T4/B4
The reg property in the pci bridge device node is used to bind this
device node to the pci bridge device. Then all the pci devices under
this bridge could use the interrupt maps defined in this device node
to do the irq translation. So if this property is missed, the pci
traditional irq mechanism will not work.

e48fc15aa2 mmc: mxcmmc: enable DMA support on mpc512x
Add SDHC DMA channel description to the mpc512x device tree to enable
slave channel requesting in the mxcmmc driver.

mpc512x DMA engine doesn't support endianness conversion when
reading/writing data from peripheral's FIFO, so we have to swap data
buffers before each DMA write and after each DMA read transfer manually.

Since chained SDHC DMA transfers are not supported on mpc512x, limit
'max_segs' tunable parameter to one and initialise it to 64 only when
running on i.MX platforms.
