powerpc/83xx: Move gianfar mdio nodes under the ethernet nodes
Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
Currently it doesn't matter where the mdio nodes are placed, but with
power management support (i.e. when sleep = <> properties will take
effect), mdio nodes placement will become important: mdio controller
is a part of the ethernet block, so the mdio nodes should be placed
correctly. Otherwise we may wrongly assume that MDIO controllers are
available during sleep.

This patch adds pmc nodes to the device tree files so that the boards
will able to use standby capability of MPC837x processors. The MPC837x
PMC controllers are compatible with MPC8349 ones (i.e. no deep sleep).
sleep = <> properties are used to specify SCCR masks as described
in "Specifying Device Power Management Information (sleep property)"
chapter in Documentation/powerpc/booting-without-of.txt.
Since I2C1 and eSDHC controllers share the same clock source, they
are now placed under sleep-nexus nodes.
A processor is able to wakeup the boards on LAN events (Wake-On-Lan),
console events (with no_console_suspend kernel command line), GPIO
events and external IRQs (IRQ1 and IRQ2).
The processor can also wakeup the boards by the fourth general purpose
timer in GTM1 block, but the GTM wakeup support isn't yet implemented
(it's tested to work, but it's unclear how can we use the quite short
GTM timers, and how do we want to expose the GTM to userspace).

mpc5200 board device trees as similar as possible so that diffs
between them only show the real differences between the boards.

FSL U-Boots use /soc8315@e0000000 node to search and fixup serial
nodes' clock-frequency properties. Though in upstream kernels we use
new naming convention -- for IMMR address space dts files specify
/immr@e0000000 nodes.
This makes FSL U-Boots fail to fixup the clock frequencies, and that
leads to serial ports misbehaviour. We can workaround the issue by
filling the clock frequency values manually.
p.s. For the same reason FSL U-Boots fail to fixup MAC addresses for
ethernet nodes, so users should either change the .dts file locally
or set MAC address via `ifconfig hw ether' command.

A published errata for ppc440epx states, that when running Linux with
both EHCI and OHCI modules loaded, the EHCI module experiences a fatal
error when a high-speed device is connected to the USB2.0, and
functions normally if OHCI module is not loaded.
There used to be recommendation to use only hi-speed or full-speed
devices with specific conditions, when respective module was unloaded.
Later, it was observed that ohci suspend is enough to keep things
going, and it was turned into workaround, as explained below.
Quote from original descriprion:
The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In
USB 2.0 Host controllers, each EHCI controller has one or more companion
controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will
contain one or more ports. For each port, only one of the controllers
is connected at any one time. In the 440EPx, there is only one OHCI
companion controller, and only one USB 2.0 Host port.
All ports on an USB 2.0 controller default to the companion
controller. If you load only an ohci driver, it will have control of
the ports and any deviceplugged in will operate, although high speed
devices will be forced to operate at full speed. When an ehci driver
is loaded, it explicitly takes control of the ports. If there is a
device connected, and / or every time there is a new device connected,
the ehci driver determines if the device is high speed or not. If it
is high speed, the driver retains control of the port. If it is not,
the driver explicitly gives the companion controller control of the
port.
The is a software workaround that uses
Initial version of the software workaround was posted to
linux-usb-devel:

The Freescale Elo DMA driver binds to all DMA channels in the device tree that
are compatible with "fsl,eloplus-dma-channel". This conflicts with the sound
drivers for the MPC8610 HPCD. On this board, the SSI uses two DMA channels and
therefore those channels are not available for general purpose use. We
change the compatible properties for these channels "fsl,ssi-dma-channel".
This works because the sound drivers don't actually check the compatible

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

The PCI bridge on the Holly board is incorrectly represented in the
device tree. The current device tree node for the PCI bridge sits
under the tsi-bridge node. That's not obviously wrong, but the PCI
bridge translates some PCI spaces into CPU address ranges which were
not translated by the "ranges" property in tsi-bridge node.
We used to get away with this problem because the PCI bridge discovery
code was also buggy, assuming incorrectly that PCI host bridge nodes
were always directly under the root bus and treating the translated
addresses as raw CPU addresses, rather than parent bus addresses.
This has since been fixed, thus breaking Holly.
This could be fixed by adding extra translations to the tsi-bridge
node, but this patch instead moves the Holly PCI bridge out of the
tsi-bridge node to the root bus. This makes the tsi-bridge node
represent only the built-in IO devices in the bridge, with a
more-or-less contiguous address range. This is the same convention
used on Freescale SoC chips, where the "soc" node represents only the
IMMR region, and the PCI and other bus bridges are separate nodes
under the root bus.

For Freescale 8xxx devices that use an MPIC, the interrupt numbers in
the device tree must be 16 greater than the values documented in the
reference manual. In these chips, the MPIC is wired to use the first
16 numbers for external interrupts, but the documentation numbers
internal interrupts from 0.
In the MPC8610 HPCD device tree, the interrupt properties for the DMA
channels for DMA2 were not the adjusted values. This fixes that.

Various instances of the EMAC core have varying: 1) number of address
match slots, 2) width of the registers for handling address match slots,
3) number of registers for handling address match slots and 4) base
offset for those registers.
As the driver stands today, it assumes that all EMACs have 4 IAHT and
GAHT 32-bit registers, starting at offset 0x30 from the register base,
with only 16-bits of each used for a total of 64 match slots.
The 405EX(r) and 460EX now use the EMAC4SYNC core rather than the EMAC4
core. This core has 8 IAHT and GAHT registers, starting at offset 0x80
from the register base, with ALL 32-bits of each used for a total of
256 match slots.
This adds a new compatible device tree entry "emac4sync" and a new,
related feature flag "EMAC_FTR_EMAC4SYNC" along with a series of macros
and inlines which supply the appropriate parameterized value based on
the presence or absence of the EMAC4SYNC feature.
The code has further been reworked where appropriate to use those macros
and inlines.
In addition, the register size passed to ioremap is now taken from the
device tree:
c4 for EMAC4SYNC cores
74 for EMAC4 cores
70 for EMAC cores
rather than sizeof (emac_regs).
Finally, the device trees have been updated with the appropriate compatible
entries and resource sizes.
This has been tested on an AMCC Haleakala board such that: 1) inbound
ICMP requests to 'haleakala.local' via MDNS from both Mac OS X 10.4.11
and Ubuntu 8.04 systems as well as 2) outbound ICMP requests from
'haleakala.local' to those same systems in the '.local' domain via MDNS
now work.
