NVIDIA Tegra MIPI pad calibration controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "nvidia,tegra<chip>-mipi"
|
||
|
|
- reg: Physical base address and length of the controller's registers.
|
||
|
|
- clocks: Must contain an entry for each entry in clock-names.
|
||
|
|
See ../clocks/clock-bindings.txt for details.
|
||
|
|
- clock-names: Must include the following entries:
|
||
|
|
- mipi-cal
|
||
|
|
- #nvidia,mipi-calibrate-cells: Should be 1. The cell is a bitmask of the pads
|
||
|
|
that need to be calibrated for a given device.
|
||
|
|
|
||
|
|
User nodes need to contain an nvidia,mipi-calibrate property that has a
|
||
|
|
phandle to refer to the calibration controller node and a bitmask of the pads
|
||
|
|
that need to be calibrated.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
mipi: mipi@700e3000 {
|
||
|
|
compatible = "nvidia,tegra114-mipi";
|
||
|
|
reg = <0x700e3000 0x100>;
|
||
|
|
clocks = <&tegra_car TEGRA114_CLK_MIPI_CAL>;
|
||
|
|
clock-names = "mipi-cal";
|
||
|
|
#nvidia,mipi-calibrate-cells = <1>;
|
||
|
|
};
|
||
|
|
|
||
|
|
...
|
||
|
|
|
||
|
|
host1x@50000000 {
|
||
|
|
...
|
||
|
|
|
||
|
|
dsi@54300000 {
|
||
|
|
...
|
||
|
|
|
||
|
|
nvidia,mipi-calibrate = <&mipi 0x060>;
|

};
