-QCOM GSBI (General Serial Bus Interface) Driver
-
-The GSBI controller is modeled as a node with zero or more child nodes, each
-representing a serial sub-node device that is mux'd as part of the GSBI
-configuration settings. The mode setting will govern the input/output mode of
-the 4 GSBI IOs.
-
-Required properties:
-- compatible: Should contain "qcom,gsbi-v1.0.0"
-- cell-index: Should contain the GSBI index
-- reg: Address range for GSBI registers
-- clocks: required clock
-- clock-names: must contain "iface" entry
-- qcom,mode : indicates MUX value for configuration of the serial interface.
- Please reference dt-bindings/soc/qcom,gsbi.h for valid mux values.
-
-Optional properties:
-- qcom,crci : indicates CRCI MUX value for QUP CRCI ports. Please reference
- dt-bindings/soc/qcom,gsbi.h for valid CRCI mux values.
-- syscon-tcsr: indicates phandle of TCSR syscon node. Required if child uses
- dma.
-
-Required properties if child node exists:
-- #address-cells: Must be 1
-- #size-cells: Must be 1
-- ranges: Must be present
-
-Properties for children:
-
-A GSBI controller node can contain 0 or more child nodes representing serial
-devices. These serial devices can be a QCOM UART, I2C controller, spi
-controller, or some combination of aforementioned devices.
-
-See the following for child node definitions:
-Documentation/devicetree/bindings/i2c/qcom,i2c-qup.txt
-Documentation/devicetree/bindings/spi/qcom,spi-qup.txt
-Documentation/devicetree/bindings/serial/qcom,msm-uartdm.txt
