This patchset adds a new basic device tree enabled machine/board file which is
based on the Samsung's Exynos4 family of SoC's. Also included in this patchset is the
dts file for Exynos4210 SoC, Samsung's SMDKV310 board and Insignal's Origen board.

The Exynos4210 dts file includes support for IRQ, GPIO, WDT, RTC, UART, SDHCI, Keypad,
DMA and I2C controllers. As device tree coverage for Exynos4210 increases, additional
device nodes to represent the controllers should be added.

The device tree enabled machine file enables boot on two boards based on the
Exynos4210 SoC. This provides a starting point to add additional device tree support
on these boards, migrate other existing Exynos4 based boards to use device tree
and enable device tree based boot on new upcoming boards.

This patchset has been tested on the following tree:

Add a new Exynos4 compatible device tree enabled board file. Boards based on
the Exynos4 family of SoC's can use this as the machine/board file. When using
this machine fike, a corresponding device tree blob which describes the board's
properties should be supplied at boot time to the kernel.

Add initial dts file for Exynos4210 SoC. This dts file describes the SoC
specific devices and properties. Along with this, add dts file for Samsung's
SMDKV310 board and Insignal's Origen board which uses the Exynos4210 dts file
and extends it to describe the board specific properties.

I'm not sure we can use 'MACH_EXYNOS4_DT' here because there are other
EXYNOS4 SoCs such as EXYNOS4212 and EXYNOS4412. So if this cannot support
other SoCs' boards, SMDK4212 and SMDK4412, we need to change the name.

And I wonder whether there is no problem with selecting this and other
boards.

Thanks.

Best regards,
Kgene.

Hi Grant and Thomas,

OK, this is ok for me.

But as I know, we need other Thomas' DT patches and some stuff is required
to re-work. So I'm not sure we can send them in this time
Anyway let me check in this weekend and if possible try to apply them for
upcoming merge window.

If any problems, let you know.

Thanks.

Best regards,
Kgene.
