-Samsung S5P/EXYNOS SoC series MIPI CSI-2 receiver (MIPI CSIS)
--------------------------------------------------------------
-
-Required properties:
-
-- compatible : "samsung,s5pv210-csis" for S5PV210 (S5PC110),
- "samsung,exynos4210-csis" for Exynos4210 (S5PC210),
- "samsung,exynos4212-csis" for Exynos4212/Exynos4412,
- "samsung,exynos5250-csis" for Exynos5250;
-- reg : offset and length of the register set for the device;
-- interrupts : should contain MIPI CSIS interrupt; the format of the
- interrupt specifier depends on the interrupt controller;
-- bus-width : maximum number of data lanes supported (SoC specific);
-- vddio-supply : MIPI CSIS I/O and PLL voltage supply (e.g. 1.8V);
-- vddcore-supply : MIPI CSIS Core voltage supply (e.g. 1.1V);
-- clocks : list of clock specifiers, corresponding to entries in
- clock-names property;
-- clock-names : must contain "csis", "sclk_csis" entries, matching entries
- in the clocks property.
-
-Optional properties:
-
-- clock-frequency : The IP's main (system bus) clock frequency in Hz, default
- value when this property is not specified is 166 MHz;
-- samsung,csis-wclk : CSI-2 wrapper clock selection. If this property is present
- external clock from CMU will be used, or the bus clock if
- if it's not specified.
-
-The device node should contain one 'port' child node with one child 'endpoint'
-node, according to the bindings defined in Documentation/devicetree/bindings/
-media/video-interfaces.txt. The following are properties specific to those nodes.
-
-port node
----------
-
-- reg : (required) must be 3 for camera C input (CSIS0) or 4 for
- camera D input (CSIS1);
-
-endpoint node
--------------
-
-- data-lanes : (required) an array specifying active physical MIPI-CSI2
- data input lanes and their mapping to logical lanes; the
- array's content is unused, only its length is meaningful;
-
-- samsung,csis-hs-settle : (optional) differential receiver (HS-RX) settle time;
-
-
-Example:
-
- reg0: regulator@0 {
- };
-
- reg1: regulator@1 {
- };
