[PATCH v7 0/7] Initial Device Tree support for S3C64xx

[Tomasz Figa]

This series adds Device Tree support for Samsung S3C64xx SoC series.

It fixes several problems preventing from booting an S3C64xx-based system
using Device Tree, adds all the infrastructure for Device Tree-based board
support, including mach-s3c64xx-dt and dts include files for S3C64xx SoCs,
and basic device tree source for FriendlyARM Mini6410 and SAMSUNG SMDK6410
boards.

Current support is somewhat limite, but should be fine as a start and
will be extended in future, hopefully with help of S3C64xx board
maintainers.

Depends on:
 - [PATCH v2 0/8] Common Clock Framework support for Samsung S3C64xx

On Samsung S3C6410-based Mini6410 and SMDK6410 boards:

Tested-by: Tomasz Figa <tomasz.figa at gmail.com>

Changes since v6:
 - Rebased onto current for-next branch of Kgene's tree,
 - Dropped the idea of .init_platform() machine callback,
 - Added support for i2c controllers,
 - Replaced separate apb and ahb nodes with a single common soc node,
 - Updated cpus node according to CPU bindings,
 - Updated fixed rate clock nodes to use generic bindings,
 - Added support for PWM buzzer and I2C EEPROM on Mini6410 board,
 - Simplified the condition of skipping legacy GPIO initialization.

Changes since v5:
 - Rebased onto current for-next branch of Kgene's tree,
 - Added support for new Common Clock Framework based clock driver,
 - Introduced hierarchical structure of device nodes (representing
   physical AHB and APB buses),
 - Bypassed most of legacy initialization when booting with DT,
 - Used preprocessor macros in dts files to improve readabilty,
 - Added support for SMDK6410 board.

Changes since v4:
 - Rebased onto current for-next branch of Kgene's tree
 - Added support for pinctrl (driver merged through pinctrl tree)
 - Added labels to all nodes that can be overridden from board dts
 - Modified board dts to use the &label syntax to reference device nodes

Changes since v3:
 - Rebased onto current for-next branch of Kgene's tree
 - Updated timer node for next version of samsung-time patches
 - Replaced local s3c64xx_dt_init_irq with irqchip_init

Changes since v2:
 - Updated timer node for next version of samsung-time patches

Changes since v1:
 - Dropped two VIC-related patches that are no longer necessary
 - Added Device Tree-based instantation of system timers
 - Corrected VIC interrupt specifiers
 - Adjusted CPU compatible values and dropped @id
