This is the serdev binding for the QCA7000 UART driver (Ethernet over UART). Signed-off-by: Stefan Wahren <redacted> --- According to this binding are still some questions: Where should be the optional hardware flow control defined (at master or slave side)? Is it okay to have two bindings (qca-qca7000-spi and qca-qca7000-uart) or should they be merged? .../devicetree/bindings/net/qca-qca7000-uart.txt | 31 ++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/qca-qca7000-uart.txt
