This patch series adds support for DRM FIMD DT for Exynos4 DT Machines, specifically for Exynos4412 SoC.
changes since v8: - addressed comments to add missing documentation for clock and clock-names properties as pointed out by Sachin Kamat sachin.kamat@linaro.org
changes since v7: - rebased to kgene's "for-next" - Migrated to Common Clock Framework - removed the patch "ARM: dts: Add FIMD AUXDATA node entry for exynos4 DT", as migration to Common Clock Framework will NOT need this. - addressed the comments raised by Sachin Kamat sachin.kamat@linaro.org
changes since v6: - addressed comments and added interrupt-names = "fifo", "vsync", "lcd_sys" in exynos4.dtsi and re-ordered the interrupt numbering to match the order in interrupt combiner IP as suggested by Sylwester Nawrocki sylvester.nawrocki@gmail.com.
changes since v5: - renamed the fimd binding documentation file name as "samsung-fimd.txt", since it not only talks about exynos display controller but also about previous samsung display controllers. - rephrased an abmigious statement about the interrupt combiner in the fimd binding documentation as pointed out by Sachin Kamat sachin.kamat@linaro.org
changes since v4: - moved the fimd binding documentation to Documentation/devicetree/bindings/video/ as suggested by Sylwester Nawrocki sylvester.nawrocki@gmail.com
- added more fimd compatiblity strings in fimd documentation as discussed at https://patchwork.kernel.org/patch/2144861/ with Sylwester Nawrocki sylvester.nawrocki@gmail.com and Tomasz Figa tomasz.figa@gmail.com
- modified compatible string for exynos4 fimd as "exynos4210-fimd" exynos5 fimd as "exynos5250-fimd" to stick to the rule that compatible value should be named after first specific SoC model in which this particular IP version was included as discussed at https://patchwork.kernel.org/patch/2144861/
- documented more about the interrupt combiner and their order as suggested by Sylwester Nawrocki sylvester.nawrocki@gmail.com
changes since v3: - rebased on http://git.kernel.org/?p=linux/kernel/git/kgene/linux-samsung.git%3Ba=shortl...
changes since v2: - added alias to 'fimd@11c00000' node (reported by: Rahul Sharma r.sh.open@gmail.com) - removed 'lcd0_data' node as there was already a similar node lcd_data24 (reported by: Jingoo Han jg1.han@samsung.com - replaced spaces with tabs in display-timing node
changes since v1: - added new patch to add FIMD DT binding Documentation - removed patch enabling SAMSUNG_DEV_BACKLIGHT and SAMSUNG_DEV_PMW for mach-exynos4 DT - added 'status' property to fimd DT node
Is based on branch kgene's "for-next" https://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git/log/?h=...

Is lcd_en a board specific configuration. If so, this has to be moved into board specfic dts file. Same with lcd_sync.

+- interrupt-parent : a phandle to the interrupt combiner node
Since the bindings documentation have to be generic across multiple platforms that uses the fimd controller, it is not right to say that the interrupt-parent phandle should be combiner node. Instead, it should just mention that it should be the phandle of the fimd controller's interrupt parent controller.
+- interrupts : should contain a list of all FIMD IP block interrupts:
- FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier format depends

to the device. Should contain clock ID as perDocumentation/devicetree/bindings/clock/exynosXXXX-clock.txt
Non-exynos platfroms can also migrate to dt. So writing file name above will be inappropriate.

Since the interrupt order is supposed to be defined by the binding, perhaps it could be rephrased to something like:
- interrupts : should contain a list of all FIMD IP block interrupts in order: FIFO Level, VSYNC, LCD_SYSTEM. The interrupt specifier format depends on the interrupt controller used.
+- interrupt-names : should contain the interrupt names: "fifo", "vsync",
"lcd_sys", in the same order as they were listed in the interruptsproperty.+- pinctrl : property defining the pinctrl configurations with a phandle
+- pinctrl-names : "default" state needs to be specified in the fimd node
The pinctrl bindings defined in../../../pinctrl/pinctrl-bindings.txt must be used to define apinctrl state named "default".
The path should be ../pinctrl/pinctrl-bindings.txt. It probably makes to sense to either have this one sentence or pinctrl/pinctrl-names properties listed with their description. So for example
- pinctrl : pin control group to be used for this controller; - pinctrl-names : should contain "default" entry;
or
The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used to define a pinctrl state named "default".
Hi Kukjin Kim,
Can you please apply these patches?
