Nicolas Pitre 6451d7783b arm: remove machine_desc.io_pg_offst and .phys_io
Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.

The various declarations were removed using the following script:

  grep -rl MACHINE_START arch/arm | xargs \
  sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'

[ Initial patch was from Jeremy Kerr, example script from Russell King ]

This patch removes davinci architecture code that has now been rendered
useless by the previous patches in the MDIO separation series.

Sekhar Nori 0b3fc7bb88 davinci: dm6467t evm: setup NAND flash timing
Setup NAND flash timing on DM6467T EVM.

Without the timing setup, the NAND flash on DM6467T
RevC EVM reports a number of random bad blocks because
of read errors.

Also, with this, copying a 100M file on RevB EVM takes
~35 sec against 1 minute 30 seconds earlier.

Sekhar Nori 48519f0ae0 ASoC: davinci: let platform data define edma queue numbers
Currently the EDMA queue to be used by for servicing ASP through
internal RAM is fixed to EDMAQ_0 and that to service internal RAM
from external RAM is fixed to EDMAQ_1.

This may not be the desirable configuration on all platforms. For
example, on DM365, queue 0 has large fifo size and is more suitable
for video transfers. Having audio and video transfers on the same
queue may lead to starvation on audio side.

platform data as defined currently passes a queue number to the driver
but that remains unused inside the driver.

Fix this by defining one queue each for ASP and RAM transfers in the
platform data and using it inside the driver.

Since EDMAQ_0 maps to 0, thats the queue that will be used if
the asp queue number is not initialized. None of the platforms
currently utilize ping-pong transfers through internal RAM so that
functionality remains unchanged too.

This patch has been tested on DM644x and OMAP-L138 EVMs.

Cyril Chemparathy bd80894704 Davinci: aintc/cpintc - use ioremap()
This patch implements the following:

 - interrupt initialization uses ioremap() instead of passing a virtual address
   via davinci_soc_info.

 - machine definitions directly point to cp_intc_init() or davinci_irq_init()

 - davinci_intc_type and davinci_intc_base now get initialized in controller
   specific init functions instead of davinci_common_init()

 - minor fix in davinci_irq_init() to use intc_irq_num instead of
   DAVINCI_N_AINTC_IRQ

Sergei Shtylyov 7a9978a1e2 DaVinci: move IDE platform device to its proper place
The IDE platform device is registered in three different places (2 board files
for DM644x and in dm646x.c for DM646x) while both the IDE base address and the
IDE IRQ are the same for both SoCs -- therefore,  the proper place for the IDE
platform seems to be in devices.c. Merge the IDE platform data and registration
code and create davinci_init_ide() in place of dm646x_init_ide()...

Sergei Shtylyov 7034217467 DaVinci: move AEMIF #define's to the proper headers
Currently each DaVinci board file #define's its own version of the EMIFA base
addresses (all named DAVINCI_ASYNC_EMIF_*_BASE), which leads to duplication.
Move these #define's to the SoC specific headers, changing their prefixes from
'DAVINCI' to the 'DM355', 'DM644X', and 'DM646X' since all these base addresses
are SoC specific...

And while at it, rename DM646X_ASYNC_EMIF_DATA_CE0_BASE to
DM646X_ASYNC_EMIF_CS2_SPACE_BASE in order to match the DM646x datasheet.

Nageswari Srinivasan 77a92c710b davinci: add CDCE949 support on DM6467 EVM
This patch adds the CDCE949 reference oscillator to
the davinci clock list.

On the DM6467T EVM, the CDCE949 is responsible for
generating the pixel clock for display. On the DM6467
EVM, this pixel clock was being obtained from an
internal source. This is not possible on the DM6467T
EVM because of the presence of a 33MHz oscillator.

The TSIF module also requires the CDCE949 to generate
the data clocks.

The actual clock definitions will be added by patches
adding support for DM6467T VPIF and TSIF. This patch
mearly lays the foundation for that work.

Sekhar Nori c1978e1dfb davinci: add support for DM6467T EVM
DM6467T (T for Turbo) is a newer and faster DM6467
part from TI. The new part supports 1080p video and
has the ARM running at 495MHz. More SoC information:

http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html

Spectrum Digital, Inc has a new EVM for this part.
It is _mostly_ same as the older DM6467 EVM except
for a 33MHz crystal input and THS8200 video encoder
for 1080p support.

The meat of this patch is dedicated to initializing
the crystal frequency from EVM board file.

Additional notes:
I did consider some alternative ways to make the crystal
input board specific including - (1) having board code
initialize the crystal frequency using the first member
of soc_info->cpu_clks array (2) introducing a new ref_clk_rate
member in soc_info structure.

But, the current way seems to be the simplest and least
intruding considering that both the clock array and SoC
info structure are actually private to the SoC file. Also
the fact that davinci_common_init() initializes both the
soc_info and clocks in one go.

Muralidharan Karicheri 85609c1ccd DaVinci: DM646x - platform changes for vpif capture and display drivers
VPIF display changes (Chaithrika)

Add platform device and resource structures. Also define a platform specific
clock setup function that can be accessed by the driver to configure the clock
and CPLD.

VPIF caputure changes (Murali)

1) Modify vpif_subdev_info to add board_info, routing information and
   vpif interface configuration. Remove addr since it is part of
   board_info

2) Add code to setup channel mode and input decoder path for vpif
   capture driver

Also incorporated comments against version v0 of the patch series and
added a spinlock to protect writes to common registers

Tested on DM6467 on channel 0 using TVP514x. Following bootargs used
for drivers:

   vpif_capture.ch0_bufsize=829440 vpif_display.ch2_bufsize=829440

Mark A. Greer 79c3c0b729 davinci: Encapsulate SoC-specific data in a structure
Create a structure to encapsulate SoC-specific information.
This will assist in generalizing code so it can be used by
different SoCs that have similar hardware but with minor
differences such as having a different base address.

The idea is that the code for each SoC fills out a structure
with the correct information.  The board-specific code then
calls the SoC init routine which in turn will call a common
init routine that makes a copy of the structure, maps in I/O
regions, etc.

After initialization, code can get a pointer to the structure
by calling davinci_get_soc_info().  Eventually, the common
init routine will make a copy of all of the data pointed to
by the structure so the original data can be made __init_data.
That way the data for SoC's that aren't being used won't consume
memory for the entire life of the kernel.

The structure will be extended in subsequent patches but
initially, it holds the map_desc structure for any I/O
regions the SoC/board wants statically mapped.
