It 16 can be connected to CMOS image sensors from various vendors, supporting both 17 MIPI CSI-2 and parallel interfaces. It can also output on either MIPI CSI-2 18 or parallel. The hardware is capable of transmitting and receiving MIPI 19 interleaved data streams with data types or multiple virtual channel 20 identifiers. 21 22allOf: 23 - $ref: /schemas/media/video-interface-devices.yaml# 24 25properties: 26 compatible: 27 const: thine,thp7312 28 29 reg: 30 maxItems: 1 31 32 clocks: 33 maxItems: 1 34 description: CLKI clock input 35 36 thine,boot-mode: 37 $ref: /schemas/types.yaml#/definitions/uint32 38 minimum: 0 39 maximum: 1 40 default: 1 41 description: 42 Boot mode of the THP7312, reflecting the value of the BOOT[0] pin strap. 43 0 is for the SPI/2-wire slave boot, 1 is for the SPI master boot (from 44 external flash ROM). 45 46 reset-gpios: 47 maxItems: 1 48 description: 49 Reference to the GPIO connected to the RESET_N pin, if any. 50 Must be released (set high) after all supplies are applied. 51 52 vddcore-supply: 53 description: 54 1.2V supply for core, PLL, MIPI rx and MIPI tx. 55 56 vhtermrx-supply: 57 description: 58 Supply for input (RX). 1.8V for MIPI, or 1.8/2.8/3.3V for parallel. 59 60 vddtx-supply: 61 description: 62 Supply for output (TX). 1.8V for MIPI, or 1.8/2.8/3.3V for parallel. 63 64 vddhost-supply: 65 description: 66 Supply for host interface. 1.8V, 2.8V, or 3.3V. 67 68 vddcmos-supply: 69 description: 70 Supply for sensor interface. 1.8V, 2.8V, or 3.3V. 71 72 vddgpio-0-supply: 73 description: 74 Supply for GPIO_0. 1.8V, 2.8V, or 3.3V. 75 76 vddgpio-1-supply: 77 description: 78 Supply for GPIO_1. 1.8V, 2.8V, or 3.3V. 79 80 orientation: true 81 rotation: true 82 83 port: 84 $ref: /schemas/graph.yaml#/$defs/port-base 85 additionalProperties: false 86 87 properties: 88 endpoint: 89 $ref: /schemas/media/video-interfaces.yaml# 90 unevaluatedProperties: false 91 92 properties: 93 bus-type: 94 const: 4 # CSI-2 D-PHY 95 96 data-lanes: 97 description: 98 This property is for lane reordering between the THP7312 and the 99 SoC.
