[PATCH 0/7] Add DT nodes for FIMD and DP controller for Exynos5420 SoC

[PATCH 0/7] Add DT nodes for FIMD and DP controller for Exynos5420 SoC

[Vikas Sajjan]

This patchset adds DT nodes for FIMD and DP controller for Exynos5420
based SMDK.

It moves all common properties of FIMD and DP controller DT node specific to
Exynos5 Socs like 5250 and 5420 to exynos5.dtsi file.

It also adds required PM domain DT nodes for exynos5420.

Is rebased on branch kgene's "for-next"
https://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git/log/?h=for-next

The DP PHY DT Node is based on Jingoo Han's inflight patchset at
http://comments.gmane.org/gmane.linux.drivers.video-input-infrastructure/66435

[PATCH 1/7] ARM: dts: Move display-timimg information inside FIMD DT node for exynos5250

[Vikas Sajjan]

As the display-timing information is parsed by FIMD driver, it makes
sense to move the display-timimg DT node inside FIMD DT node for exynos5250

I don't know why this node was named incorrectly in original file (probably the 
patch adding it did not have enough review), but if you are modifying it 
anyway, could you fix it to be conformant to DT conventions?

Whenever there is a reg property inside a node, the node should be named 
whatever@addr, where addr is comma separated list of addresses specified in reg 
property, in hex, without "0x" prefix.

So in this case this should be at least

	fimd@14400000

but ideally

	display-controller@14400000

as nodes should have generic names (see ePAPR, paragraph 2.2.2).

Best regards,
Tomasz

Please use power-domain for node names. We might have "pd" for other Exynos 
SoCs, but this needs to be fixed.

FIMD can't operate without display timings, so status = "okay" doesn't 
represent real device state here. Please move status override to board dts.

I know that dtsi files of Exynos 5 SoCs have "okay" status as default, but this 
is broken and needs to be fixed, because it moves the responsibility of knowing 
about all SoC hardware to board dts.

Generally, the ePAPR document, chapter 2.3.4, specifies following definition of 
status property:

	The status property indicates the operational status of a device. Valid 
	values are listed and defined in the following table.

The table specifies following values:

	“okay”
	Indicates the device is operational

	“disabled”
	Indicates that the device is not presently operational, but it might become 
	operational in the future (for example, something is not plugged in, or 		
	switched off). Refer to the device binding for details on what disabled 
	means for a given device.

	“fail”
	Indicates that the device is not operational. A serious error was detected 
	in the device, and it is unlikely to become operational without repair.

	“fail-sss”
	Indicates that the device is not operational. A serious error was detected 	
	in the device and it is unlikely to become operational without repair. The 
	sss portion of the value is specific to the device and indicates the error 
	condition detected.

Without all required properties the device will not be operational, so its 
status should be set to "disabled" and then overriden to "okay" when missing 
properties are provided (e.g. in board dts).

Best regards,
Tomasz
