Convert the Samsung S5P/Exynos Camera Subsystem (FIMC) bindings to DT
schema.  Changes during conversion - adjust to existing DTS and Linux
driver: add iommus and power-domains.

Changes since v2:
1. Add Rb tag.
2. Move size-cells next to address-cells.

The patch depends on:

This does not apply on top of -rc1.

...

I guess you have another patch removing "simple-bus" here and another
location in your tree?

Ah, what's missing seems to be this set:

<URL:https://patchwork.linuxtv.org/project/linux-media/list/?series=9839>

But also the second patch of that set doesn't seem to apply. :-(

Yeah, dependency is mention in cover letter.

Yep, I forgot I already sent same patch two months earlier. Let me merge
two patches, rebase and resent, so everything will be easier for you
(hopefully). Sorry for the mess.

No worries. I was expecting a comment from the author but never saw one...

Thanks for refreshing the set.

-Samsung S5P/Exynos SoC Camera Subsystem (FIMC)
-----------------------------------------------
-
-The S5P/Exynos SoC Camera subsystem comprises of multiple sub-devices
-represented by separate device tree nodes. Currently this includes: FIMC (in
-the S5P SoCs series known as CAMIF), MIPI CSIS, FIMC-LITE and FIMC-IS (ISP).
-
-The sub-subdevices are defined as child nodes of the common 'camera' node which
-also includes common properties of the whole subsystem not really specific to
-any single sub-device, like common camera port pins or the CAMCLK clock outputs
-for external image sensors attached to an SoC.
-
-Common 'camera' node
---------------------
-
-Required properties:
-
-- compatible: must be "samsung,fimc"
-- clocks: list of clock specifiers, corresponding to entries in
-  the clock-names property;
-- clock-names : must contain "sclk_cam0", "sclk_cam1", "pxl_async0",
-  "pxl_async1" entries, matching entries in the clocks property.
-
-- #clock-cells: from the common clock bindings (../clock/clock-bindings.txt),
-  must be 1. A clock provider is associated with the 'camera' node and it should
-  be referenced by external sensors that use clocks provided by the SoC on
-  CAM_*_CLKOUT pins. The clock specifier cell stores an index of a clock.
-  The indices are 0, 1 for CAM_A_CLKOUT, CAM_B_CLKOUT clocks respectively.
-
-- clock-output-names: from the common clock bindings, should contain names of
-  clocks registered by the camera subsystem corresponding to CAM_A_CLKOUT,
-  CAM_B_CLKOUT output clocks respectively.
-
-The pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt must be used
-to define a required pinctrl state named "default" and optional pinctrl states:
-"idle", "active-a", active-b". These optional states can be used to switch the
-camera port pinmux at runtime. The "idle" state should configure both the camera
-ports A and B into high impedance state, especially the CAMCLK clock output
-should be inactive. For the "active-a" state the camera port A must be activated
-and the port B deactivated and for the state "active-b" it should be the other
-way around.
-
-The 'camera' node must include at least one 'fimc' child node.
-
-
-'fimc' device nodes
--------------------
-
-Required properties:
-
-- compatible: "samsung,s5pv210-fimc" for S5PV210, "samsung,exynos4210-fimc"
-  for Exynos4210 and "samsung,exynos4212-fimc" for Exynos4x12 SoCs;
-- reg: physical base address and length of the registers set for the device;
-- interrupts: should contain FIMC interrupt;
-- clocks: list of clock specifiers, must contain an entry for each required
-  entry in clock-names;
-- clock-names: must contain "fimc", "sclk_fimc" entries.
-- samsung,pix-limits: an array of maximum supported image sizes in pixels, for
-  details refer to Table 2-1 in the S5PV210 SoC User Manual; The meaning of
-  each cell is as follows:
-  0 - scaler input horizontal size,
-  1 - input horizontal size for the scaler bypassed,
-  2 - REAL_WIDTH without input rotation,
-  3 - REAL_HEIGHT with input rotation,
-- samsung,sysreg: a phandle to the SYSREG node.
-
-Each FIMC device should have an alias in the aliases node, in the form of
-fimc<n>, where <n> is an integer specifying the IP block instance.
-
-Optional properties:
-
-- clock-frequency: maximum FIMC local clock (LCLK) frequency;
-- samsung,min-pix-sizes: an array specyfing minimum image size in pixels at
-  the FIMC input and output DMA, in the first and second cell respectively.
-  Default value when this property is not present is <16 16>;
-- samsung,min-pix-alignment: minimum supported image height alignment (first
-  cell) and the horizontal image offset (second cell). The values are in pixels
-  and default to <2 1> when this property is not present;
-- samsung,mainscaler-ext: a boolean property indicating whether the FIMC IP
-  supports extended image size and has CIEXTEN register;
-- samsung,rotators: a bitmask specifying whether this IP has the input and
-  the output rotator. Bits 4 and 0 correspond to input and output rotator
-  respectively. If a rotator is present its corresponding bit should be set.
-  Default value when this property is not specified is 0x11.
-- samsung,cam-if: a bolean property indicating whether the IP block includes
-  the camera input interface.
-- samsung,isp-wb: this property must be present if the IP block has the ISP
-  writeback input.
-- samsung,lcd-wb: this property must be present if the IP block has the LCD
-  writeback input.
-
-
-'parallel-ports' node
----------------------
-
-This node should contain child 'port' nodes specifying active parallel video
-input ports. It includes camera A and camera B inputs. 'reg' property in the
-port nodes specifies data input - 1, 2 indicates input A, B respectively.
-
-Optional properties
-
-- samsung,camclk-out (deprecated) : specifies clock output for remote sensor,
-  0 - CAM_A_CLKOUT, 1 - CAM_B_CLKOUT;
-
-Image sensor nodes
-------------------
-
-The sensor device nodes should be added to their control bus controller (e.g.
-I2C0) nodes and linked to a port node in the csis or the parallel-ports node,
-using the common video interfaces bindings, defined in video-interfaces.txt.
