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: must contain "qcom,gsbi-v1.0.0" for APQ8064/IPQ8064
|
||||
- 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.
|
||||
|
||||
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:

||||
