| Qualcomm Technologies, Inc. G-link SPI Transport |
| |
| Required properties: |
| -compatible : should be "qcom,glink-spi-xprt". |
| -label : the name of the subsystem this link connects to. |
| |
| Optional properties: |
| -qcom,remote-fifo-config: Reference to the FIFO configuratio in the remote |
| processor. |
| -qcom,qos-config: Reference to the qos configuration elements.It depends on |
| ramp-time. |
| -qcom,ramp-time: Worst case time in microseconds to transition to this power |
| state. Power states are numbered by array index position. |
| |
| Example: |
| |
| glink_spi_xprt_wdsp: qcom,glink-spi-xprt-wdsp { |
| compatible = "qcom,glink-spi-xprt"; |
| label = "wdsp"; |
