Possible values are: - 1 - MIPI CSI-2 C-PHY - 2 - MIPI CSI1 - 3 - CCP2 - 4 - MIPI CSI-2 D-PHY - 5 - Parallel - 6 - Bt.656 -- bus-width: number of data lines actively used, valid for the parallel busses. -- data-shift: on the parallel data busses, if bus-width is used to specify the - number of data lines, data-shift can be used to specify which data lines are - used, e.g. "bus-width=<8>; data-shift=<2>;" means, that lines 9:2 are used. -- hsync-active: active state of the HSYNC signal, 0/1 for LOW/HIGH respectively. -- vsync-active: active state of the VSYNC signal, 0/1 for LOW/HIGH respectively. - Note, that if HSYNC and VSYNC polarities are not specified, embedded - synchronization may be required, where supported. -- data-active: similar to HSYNC and VSYNC, specifies data line polarity. -- data-enable-active: similar to HSYNC and VSYNC, specifies the data enable - signal polarity. -- field-even-active: field signal level during the even field data transmission. -- pclk-sample: sample data on rising (1) or falling (0) edge of the pixel clock - signal. -- sync-on-green-active: active state of Sync-on-green (SoG) signal, 0/1 for - LOW/HIGH respectively. -- data-lanes: an array of physical data lane indexes. Position of an entry - determines the logical lane number, while the value of an entry indicates - physical lane, e.g. for 2-lane MIPI CSI-2 bus we could have - "data-lanes = <1 2>;", assuming the clock lane is on hardware lane 0. - If the hardware does not support lane reordering, monotonically - incremented values shall be used from 0 or 1 onwards, depending on - whether or not there is also a clock lane. This property is valid for - serial busses only (e.g. MIPI CSI-2). -- clock-lanes: an array of physical clock lane indexes. Position of an entry - determines the logical lane number, while the value of an entry indicates - physical lane, e.g. for a MIPI CSI-2 bus we could have "clock-lanes = <0>;", - which places the clock lane on hardware lane 0. This property is valid for - serial busses only (e.g. MIPI CSI-2). Note that for the MIPI CSI-2 bus this - array contains only one entry. -- clock-noncontinuous: a boolean property to allow MIPI CSI-2 non-continuous - clock mode. -- link-frequencies: Allowed data bus frequencies. For MIPI CSI-2, for - instance, this is the actual frequency of the bus, not bits per clock per - lane value. An array of 64-bit unsigned integers. -- lane-polarities: an array of polarities of the lanes starting from the clock - lane and followed by the data lanes in the same order as in data-lanes. - Valid values are 0 (normal) and 1 (inverted). The length of the array - should be the combined length of data-lanes and clock-lanes properties. - If the lane-polarities property is omitted, the value must be interpreted - as 0 (normal). This property is valid for serial busses only. -- strobe: Whether the clock signal is used as clock (0) or strobe (1). Used - with CCP2, for instance. - -Example -------- - -The example snippet below describes two data pipelines. ov772x and imx074 are -camera sensors with a parallel and serial (MIPI CSI-2) video bus respectively. -Both sensors are on the I2C control bus corresponding to the i2c0 controller -node. ov772x sensor is linked directly to the ceu0 video host interface. -imx074 is linked to ceu0 through the MIPI CSI-2 receiver (csi2). ceu0 has a -(single) DMA engine writing captured data to memory. ceu0 node has a single -'port' node which may indicate that at any time only one of the following data -pipelines can be active: ov772x -> ceu0 or imx074 -> csi2 -> ceu0. - - ceu0: ceu@fe910000 { - compatible = "renesas,sh-mobile-ceu"; - reg = <0xfe910000 0xa0>; - interrupts = <0x880>; - - mclk: master_clock { - compatible = "renesas,ceu-clock"; - #clock-cells = <1>; - clock-frequency = <50000000>; /* Max clock frequency */ - clock-output-names = "mclk"; - }; - - port { - #address-cells = <1>; - #size-cells = <0>; - - /* Parallel bus endpoint */ - ceu0_1: endpoint@1 { - reg = <1>; /* Local endpoint # */ - remote = <&ov772x_1_1>; /* Remote phandle */ - bus-width = <8>; /* Used data lines */ - data-shift = <2>; /* Lines 9:2 are used */ - - /* If hsync-active/vsync-active are missing, - embedded BT.656 sync is used */ - hsync-active = <0>; /* Active low */ - vsync-active = <0>; /* Active low */ - data-active = <1>; /* Active high */ - pclk-sample = <1>; /* Rising */ - }; - - /* MIPI CSI-2 bus endpoint */ - ceu0_0: endpoint@0 { - reg = <0>; - remote = <&csi2_2>; - }; - }; - }; - - i2c0: i2c@fff20000 { - ... - ov772x_1: camera@21 { - compatible = "ovti,ov772x"; - reg = <0x21>; - vddio-supply = <®ulator1>; - vddcore-supply = <®ulator2>; - - clock-frequency = <20000000>; - clocks = <&mclk 0>; - clock-names = "xclk"; - - port { - /* With 1 endpoint per port no need for addresses. */ - ov772x_1_1: endpoint { - bus-width = <8>; - remote-endpoint = <&ceu0_1>; - hsync-active = <1>; - vsync-active = <0>; /* Who came up with an - inverter here ?... */ - data-active = <1>; - pclk-sample = <1>; - }; - }; - }; - - imx074: camera@1a { - compatible = "sony,imx074"; - reg = <0x1a>; - vddio-supply = <®ulator1>; - vddcore-supply = <®ulator2>; - - clock-frequency = <30000000>; /* Shared clock with ov772x_1 */ - clocks = <&mclk 0>; - clock-names = "sysclk"; /* Assuming this is the - name in the datasheet */ - port { - imx074_1: endpoint { - clock-lanes = <0>; - data-lanes = <1 2>; - remote-endpoint = <&csi2_1>; - }; - }; - }; - }; - - csi2: csi2@ffc90000 { - compatible = "renesas,sh-mobile-csi2"; - reg = <0xffc90000 0x1000>; - interrupts = <0x17a0>; - #address-cells = <1>; - #size-cells = <0>; - - port@1 { - compatible = "renesas,csi2c"; /* One of CSI2I and CSI2C. */ - reg = <1>; /* CSI-2 PHY #1 of 2: PHY_S, - PHY_M has port address 0, - is unused. */ - csi2_1: endpoint { - clock-lanes = <0>; - data-lanes = <2 1>; - remote-endpoint = <&imx074_1>; - }; - }; - port@2 { - reg = <2>; /* port 2: link to the CEU */ - - csi2_2: endpoint { - remote-endpoint = <&ceu0_0>; - }; - }; - }; +This file has moved to video-interfaces.yaml and video-interface-devices.yaml. diff --git a/Documentation/devicetree/bindings/media/video-interfaces.yaml b/Documentation/devicetree/bindings/media/video-interfaces.yaml new file mode 100644 index 000000000000..fefca7d98718 --- /dev/null +++ b/Documentation/devicetree/bindings/media/video-interfaces.yaml @@ -0,0 +1,346 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/video-interfaces.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Common bindings for video receiver and transmitter interface endpoints + +maintainers: + - Guennadi Liakhovetski + - Sakari Ailus + +description: | + Video data pipelines usually consist of external devices, e.g. camera sensors, + controlled over an I2C, SPI or UART bus, and SoC internal IP blocks, including + video DMA engines and video data processors. + + SoC internal blocks are described by DT nodes, placed similarly to other SoC + blocks.

An endpoint subnode of a device contains all properties needed for + configuration of this device for data exchange with other device. In most + cases properties at the peer 'endpoint' nodes will be identical, however they + might need to be different when there is any signal modifications on the bus + between two devices, e.g. there are logic signal inverters on the lines. + + It is allowed for multiple endpoints at a port to be active simultaneously, + where supported by a device.
