Patches are generated using the "format-patch" command from the following location: *https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base *rev=0771849495b4128cac2faf7d49c85c729fc48b20 Patches numbered 76/77/102/103 have already been integrated in 3.14.12, so they're not in this list. All these patches are either integrated are pending integration into kernel.org, therefore these patches should go away once the kernel gets upgraded to 3.16. Support is currently limited to AP148 board but can be extended to other platforms in the future. These changes do not cover ethernet connectivity.

+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:
