d65566e50b ARM: davinci: mark spi_board_info arguments as const
spi_board_info is not modified in any of the spi registeration
functions and passed along as-is to the generic SPI layer.

Mark spi_board_info arguments as const to signal this.

af946f2699 ARM: davinci: dm644x: add support for v4l2 video display
Add functions to register various video devices like venc, osd,
vpbe and the v4l2 display driver for dm644x.

Change dm644x_init_video() to make room for display related
configuration. Register the vpfe or vpbe devices only if valid
display configuration is provided to make sure boards without
video support dont erroneously register video devices.

12db9588ff ARM: davinci: dm644x: don't force vpfe registeration on all boards
Move all vpfe platform device registrations to the board specific
file.

This removes registration of vpfe platform devices on boards which
do not use vpfe.

5cfb19ac60 ARM: davinci: streamline sysmod access
There are instances of IO_ADDRESS() being used for system module
(sysmod) register access. Eliminate this in favor of a ioremap()
based access. ioremap() the entire sysmod address space once during
boot-up and provide a helper macro to access specific register
offsets within the address space.

With this, also eliminate ioremap() of specific sysmodule registers
related to VPIF happening in DM646x EVM code.

While at it, also eliminate some duplicate sysmod register offset macros
defined in code and place offset definitions at one place in davinci.h

[nsekhar@ti.com: removed the addition of ifndef __ASSEMBLER__
in davinci.h, eliminate IO_ADDRESS() usage left out in dm646x.c,
cleanup VPIF sysmodule register access as part of this patch and
keep all sysmod offsets in davinci.h Also, convert the WARN_ON()
on failure to setup sysmod base to BUG_ON()]

39c6d2d1d7 ARM: davinci: create new common platform header for davinci
Remove individual platform header files for dm365, dm355, dm644x
and dm646x and consolidate it into a single and common
header file davinci.h placed in arch/arm/mach-davinci.

This reduces the pollution in the include/mach and is consistent
with Russell's suggestions as part of his "pet peaves" mail.
(See #4 in: http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071516.html)

While at it, fix the forward declaration of spi_board_info,
and include the right header file instead.

The further patches in the series take  advantage of this consolidation
for easy implementation of IO_ADDRESS elimination.
