| 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>; | ||
