Olof Johansson be2553ffb5 [POWERPC] pasemi: Register i2c devices at boot
Setup i2c_board_info based on device tree contents.  This has to be
a device_initcall since we need PCI to be probed by the time we
run it, but before the actual driver is initialized.

Olof Johansson 8ee9d85779 pasemi: DMA engine management library
pasemi: DMA engine management library

Introduce a DMA management library to manage the various DMA resources
on the PA Semi SoCs. Since several drivers need to allocate these shared
resources, provide some abstractions as well as allocation/free functions
for channels, etc.

Olof Johansson 9cd55be4d2 [POWERPC] pasemi: Move electra-ide to pata_of_platform
Move electra-ide glue over to the new pata_of_platform framework, and
add the quirks needed to that driver.

Olof Johansson 8fa336d889 [POWERPC] pasemi: Electra IDE/pata_platform glue
Glue code to hook up the pata_platform on the PA Semi Electra eval board.
CFE sets up device tree entries for the IDE interface, with device type
'ide' and compatible field 'electra-ide'.

We unfortunately need to modify the resources before calling the generic
platform driver, since the device tree only has one register window in
it and the driver expects two.  Adding this as an of_platform driver
instead doesn't give us any benefit, it just adds one more layer of
register/probe functions.

Since CONFIG_PATA_PLATFORM depends on CONFIG_EMBEDDED, add that as a
default for PPC_PASEMI.

Olof Johansson 116ab40df8 [POWERPC] pasemi: Kconfig for gpio_mdio
arch/powerpc/platforms/pasemi/gpio_mdio.c really depends on CONFIG_PHYLIB.
Add a config option for it, allow for it to be disabled if needed and fix
the dependency.

Olof Johansson 1e76875e51 [POWERPC] powerpc: PA Semi PWRficient platform support
Base patch for PA6T and PA6T-1682M. This introduces the
arch/powerpc/platform/pasemi directory, together with basic
implementations for various setup.

Much of this was based on other platform code, i.e. Maple, etc.
