cover ARM: dts: Exynos4 dts reorganization

This patch series prepares existing Exynos4210 DT infrastructure to be further extended for new SoCs from Exynos4 line and new boards.

Tomasz Figa (3):
ARM: dts: Move parts common to Exynos4 from Exynos4210.dtsi to
Exynos4.dtsi
ARM: EXYNOS: exynos4-dt: Use exynos4 prefix instead of exynos4210
ARM: dts: exynos4: Assume status of all optional nodes as disabled

PATCH 1/3 ARM: dts: Move parts common to Exynos4 from Exynos4210.dtsi to Exynos4.dtsi

Most definitions from Exynos4210.dtsi can be applied for other SoCs from Exynos4 line as well, so move the common part into separate file that can be included by dtsi files of other Exynos4 SoCs (as well as current Exynos4210.dtsi).

PATCH 2/3 ARM: EXYNOS: exynos4-dt: Use exynos4 prefix instead of exynos4210

In reply to Tomasz Figa

Since mach-exynos4-dt.c is also going to be used for other SoCs from Exynos4 line, rename internal structures and functions to use exynos4_ prefix, instead of exynos4210_.

PATCH 3/3 ARM: dts: exynos4: Assume status of all optional nodes as disabled

In reply to Tomasz Figa

Currently all boards must explicitly disable all unused device tree nodes of unused components (e.g. i2c, sdhci, etc...). This makes it necessary to all boards to be aware of all components on the SoC, which in turns makes board dts files longer and more difficult to maintain (e.g. adding new components to SoC-level tree requires adding nodes with status="disabled" to every board).

This patch changes "status" of all optional components in SoC-level dts file to "disabled", adds status="okay" to respective nodes of used components in dts of all boards and removes all nodes with only status="disabled" from boards dts.

Well...I'm not sure about the status of Origen serial, but all of the serials are enabled on SMDKV310, is it right?

Thanks.

This patch adds status override of serial nodes to enable used serial ports
on Origen and SMDKV310 board.

Well...I'm not sure about the status of Origen serial, but all of the serials are enabled on SMDKV310, is it right?

According to arrays of struct s3c2410_uartcfg in mach-origen.c and mach- smdkv310.c, all the four serial ports are enabled on both boards.

This patch series prepares existing Exynos4210 DT infrastructure to be further extended for new SoCs from Exynos4 line and new boards.

Tomasz Figa (3):
ARM: dts: Move parts common to Exynos4 from Exynos4210.dtsi to
Exynos4.dtsi
ARM: EXYNOS: exynos4-dt: Use exynos4 prefix instead of exynos4210
ARM: dts: exynos4: Assume status of all optional nodes as disabled

Thanks, we can build Exynos4412 device tree support on top of this series.

Thomas, thanks for your ack on this series and I'm OK on this series.

But you know, Donjin Kim submitted almost same patch except gpio stuff one month before this series but needs to update something though. So would be nice if either Tomasz or Dongjin could ack on the other patch?

Thanks.

Best regards,
Kgene.

Hmm...OK, I couldn't get any response from anyone so I will pick up this patches. If any objection, please let me know.

Of course, if any regarding patches, need to work against on them.

Thanks.
