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