dt-bindings: usb: add common Type-C USB Switch schema

2024-01-28T01:36:37+00:00

Several bindings implement parts of Type-C USB orientation and mode switching, and retiming. Keep definition of such properties in one place, new usb-switch schema, to avoid duplicate defines.

dt-bindings: usb: fsa4480: Add compatible for OCP96011

2023-10-27T10:54:29+00:00

The Orient-Chip OCP96011 is generally compatible with the FSA4480, add a compatible for it with the fallback on fsa4480. However the AUX/SBU connections are expected to be swapped compared to FSA4480, so document this in the data-lanes description.

dt-bindings: usb: fsa4480: Add data-lanes property to endpoint

2023-10-27T10:54:29+00:00

Allow specifying data-lanes to reverse the muxing orientation between AUX+/- and SBU1/2 where necessary by the hardware design. In the mux there's a switch that needs to be controlled from the OS, and it either connects AUX+ -> SBU1 and AUX- -> SBU2, or the reverse: AUX+ -> SBU2 and AUX- -> SBU1, depending on the orientation of how the USB-C connector is plugged in. With this data-lanes property we can now specify that AUX+ and AUX- connections are swapped between the SoC and the mux, therefore the OS needs to consider this and reverse the direction of this switch in the mux. _______ _______ | | | |-- HP --| | |-- MIC --| |or SoC | | MUX |-- SBU1 ---> To the USB-C Codec |-- AUX+ --| |-- SBU2 ---> connected |-- AUX- --| | ______| |_____| (thanks to Neil Armstrong for this ASCII art) Signed-off-by: Luca Weiss Reviewed-by: Rob Herring Link: https://lore.kernel.org/r/20231020-fsa4480-swap-v2-1-9a7f9bb59873@fairphone.com Signed-off-by: Greg Kroah-Hartman

dt-bindings: usb: Drop unneeded quotes

Cleanup bindings dropping unneeded quotes. Once all these are fixed, checking for this can be enabled in yamllint. Signed-off-by: Rob Herring Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20230320233904.2920197-1-robh@kernel.org Signed-off-by: Greg Kroah-Hartman

dt-bindings: usb: fsa4480: Use generic node name

Node names should be generic. Change fsa4480@ to typec-mux@. Fixes: 01afa882f12d ("dt-bindings: usb: Add binding for fcs,fsa4480") Signed-off-by: Konrad Dybcio Acked-by: Rob Herring Link: https://lore.kernel.org/r/20230130113151.2130063-1-konrad.dybcio@linaro.org Signed-off-by: Greg Kroah-Hartman

dt-bindings: usb: Add binding for fcs,fsa4480

2022-04-26T11:47:13+00:00

The Fairchild/ON Semiconductor FSA4480 Analog Audio switch is used in USB Type-C configurations for muxing analog audio onto the USB connector, and as such used to control the SBU signals for altmodes such as DisplayPort. Add a binding for this hardware block.
