TCPCI stands for typec port controller interface, its implementation has full typec port control with power delivery support, it's a standard i2c slave with GPIO input as irq interface, detail see spec "Universal Serial Bus Type-C Port Controller Interface Specification Revision 1.0, Version 1.1" Signed-off-by: Li Jun <jun.li@nxp.com> --- Change for v2: - Use usb connector sub-node accordingly to specify typec properties. .../devicetree/bindings/usb/typec-tcpci.txt | 35 ++++++++++++++++++++++ 1 file changed, 35 insertions(+)
