| 2 | |
| 3 | The Toshiba TC358743 HDMI-RX to MIPI CSI2-TX (H2C) is a bridge that converts |
| 4 | a HDMI stream to MIPI CSI-2 TX. It is programmable through I2C. |
| 5 | |
| 6 | Required Properties: |
| 7 | |
| 8 | - compatible: value should be "toshiba,tc358743" |
| 9 | - clocks, clock-names: should contain a phandle link to the reference clock |
| 10 | source, the clock input is named "refclk". |
| 11 | |
| 12 | Optional Properties: |
| 13 | |
| 14 | - reset-gpios: gpio phandle GPIO connected to the reset pin |
| 15 | - interrupts: GPIO connected to the interrupt pin |
| 16 | - data-lanes: should be <1 2 3 4> for four-lane operation, |
| 17 | or <1 2> for two-lane operation |
| 18 | - clock-lanes: should be <0> |
| 19 | - clock-noncontinuous: Presence of this boolean property decides whether the |
| 20 | MIPI CSI-2 clock is continuous or non-continuous. |
| 21 | - link-frequencies: List of allowed link frequencies in Hz. Each frequency is |
| 22 | expressed as a 64-bit big-endian integer. The frequency |
| 23 | is half of the bps per lane due to DDR transmission. |
| 24 | |

| 26 | Documentation/devicetree/bindings/media/video-interfaces.txt. |

| 34 | clock-names = "refclk"; |
| 35 | reset-gpios = <&gpio6 9 GPIO_ACTIVE_LOW>; |
| 36 | interrupt-parent = <&gpio2>; |
| 37 | interrupts = <5 IRQ_TYPE_LEVEL_HIGH>; |
| 38 | |
| 39 | port { |
| 40 | tc358743_out: endpoint { |
| 41 | remote-endpoint = <&mipi_csi2_in>; |
| 42 | data-lanes = <1 2 3 4>; |
| 43 | clock-lanes = <0>; |
| 44 | clock-noncontinuous; |
| 45 | link-frequencies = /bits/ 64 <297000000>; |
