1 | NVIDIA Tegra MIPI pad calibration controller |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: "nvidia,tegra<chip>-mipi" | |
| 5 | - reg: Physical base address and length of the controller's registers. | |
| 6 | - clocks: Must contain an entry for each entry in clock-names. | |
| 7 | See ../clocks/clock-bindings.txt for details. | |
| 8 | - clock-names: Must include the following entries: | |
| 9 | - mipi-cal | |
| 10 | - #nvidia,mipi-calibrate-cells: Should be 1. The cell is a bitmask of the pads | |
| 11 | that need to be calibrated for a given device. | |
| 12 | ||
| 13 | User nodes need to contain an nvidia,mipi-calibrate property that has a | |
| 14 | phandle to refer to the calibration controller node and a bitmask of the pads | |
| 15 | that need to be calibrated. | |
| 16 | ||
| 17 | Example: | |
| 18 | ||
| 19 | mipi: mipi@700e3000 { | |
| 20 | compatible = "nvidia,tegra114-mipi"; | |
| 21 | reg = <0x700e3000 0x100>; | |
| 22 | clocks = <&tegra_car TEGRA114_CLK_MIPI_CAL>; | |
| 23 | clock-names = "mipi-cal"; | |
| 24 | #nvidia,mipi-calibrate-cells = <1>; | |
| 25 | }; | |
| 26 | ||
| 27 | ... | |
| 28 | ||
| 29 | host1x@50000000 { | |

| 31 | ||
| 32 | dsi@54300000 { | |
| 33 | ... | |
| 34 | ||
| 35 | nvidia,mipi-calibrate = <&mipi 0x060>; | |
