cover ARM: Samsung: Add basic device tree support for Exynos4 boards

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:
https://github.com/kgene/linux-samsung.git branch: for-next

PATCH 1/2 ARM: Samsung: Add Exynos4 device tree enabled board file

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.

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.

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.

Quoted 2 lines

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

I think this should be fine assuming most things are common. Generally, the differences can be handled by different DT's. The board compatible string can be used to handle differences.

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.

cover ARM: Samsung: Add basic device tree support for Exynos4 boards

In reply to Thomas Abraham
Quoted 29 lines · Thomas Abraham

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:
https://github.com/kgene/linux-samsung.git branch: for-next
