Anton Vorontsov c9c5e52d44 powerpc/83xx: Add USB Host/Gadget support for MPC8360E-MDS boards
- Update the device tree per QE USB bindings;
- Add timer (FSL GTM) node;
- Add gpio-controller node for BCSR13 bank (GPIOs on that bank
  are used to control the USB transceiver);
- Set up other BCSR registers;
- Configure the QE Par IO.

The work is loosely based on Li Yang's patch[1], which was used
to support peripheral mode only.

[1] http://ozlabs.org/pipermail/linuxppc-dev/2008-August/061357.html

The s-o-b line of the original patch preserved here.

Kim Phillips cf0d19fb30 powerpc/fsl: proliferate simple-bus compatibility to soc nodes
add simple-bus compatible property to soc nodes for 83xx/85xx platforms
that were missing them.  Add same to platform probe code.

This fixes SoC device drivers (such as talitos) to succeed in matching
devices present in the soc node.

also update mpc836x_rdk dts to new SEC bindings (overlooked in commit
3fd4473: powerpc/fsl: update crypto node definition and device tree
instances).

Anton Vorontsov a2dd70a11d [POWERPC] QE: get rid of most device_types and model
Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data"
and "fsl,qe-ic".

Unfortunately it's still impossible to remove device_type = "qe"
from the existing device trees because older u-boots are looking for it.

Anton Vorontsov cccd21027c [POWERPC] QEIC: Implement pluggable handlers, fix MPIC cascading
set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.

To solve this problem efficiently, QEIC needs pluggable handlers,
specific to the underlaying interrupt controller.

Patch extends qe_ic_init() function to accept low and high interrupt
handlers. To avoid #ifdefs, stack of interrupt handlers specified in
the header file and functions are marked 'static inline', thus
handlers are compiled-in only if actually used (in the board file).
Another option would be to lookup for parent controller and
automatically detect handlers (will waste text size because of
never used handlers, so this option abolished).

qe_ic_init() also changed in regard to support multiplexed high/low
lines as found in MPC8568E-MDS, plus qe_ic_cascade_muxed_mpic()
handler implemented appropriately.

Kumar Gala c9438affcb [POWERPC] Use for_each_ matching routinues for pci PHBs
On the Freescale embedded (83xx, 85xx, 86xx) and a few of the discrete
bridges (mpc10x, tsi108) use the new for_each_compatible_node() or
for_each_node_by_type() to provide more exact matching when looking for
PHBs in the device tree.

With the previous code it was possible to match on pci bridges since
we were only matching on device_type.

Kim Phillips 3c5ede8cc6 [POWERPC] Revert "[POWERPC] Add 'mdio' to bus scan id list for platforms with QE UEC"
This reverts commit 3baee95595.

That commit was a mistake from the start; I added mdio type to the
bus scan list early on in my ucc_geth migrate to phylib development,
which is just pure wrong (the ucc_geth_mii driver creates the mii
bus and the PHY layer handles PHY enumeration without translation).

This follows on from commit 77926826f301fbd8ed96d3cd9ff17a5b59560dfb:

 Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"

which was basically trying to hide a symptom of the original mistake
this revert fixes.

Arnd Bergmann 3dfaa762b5 [POWERPC] kill isa_{io,mem}_base definitions for !PCI
When CONFIG_PCI is disabled, the definitions for isa_io_base,
isa_mem_base and pci_dram_offset are entirely unused, but they
can result in link failure because they are defined in multiple
places.

The easiest fix is to just remove all these definitions.
