This sensors are fully controlled through spidev driver, with a simple register based interface and they have no other connections as the SPI lines, so they only need a compatible entry. bye, Heiko >> >>> >>> Signed-off-by: Heiko Schocher <hs@denx.de> >>> --- >>> >>> Documentation/devicetree/bindings/trivial-devices.yaml | 2 ++ >>> 1 file changed, 2 insertions(+) >>> >>> diff --git a/Documentation/devicetree/bindings/trivial-devices.yaml >>> b/Documentation/devicetree/bindings/trivial-devices.yaml >>> index 27930708ccd5..25260c2b81df 100644 >>> --- a/Documentation/devicetree/bindings/trivial-devices.yaml >>> +++ b/Documentation/devicetree/bindings/trivial-devices.yaml >>> @@ -30,6 +30,8 @@ properties: >>> items: >>> # Entries are sorted alphanumerically by the compatible >>> - enum: >>> + # ABB register based spi sensors >>> + - abb,spi-sensor >>> # Acbel fsg032 power supply >>> - acbel,fsg032 >>> # SMBus/I2C Digital Temperature Sensor in 6-Pin SOT with SMBus Alert and Over >>> Temperature Pin >>> -- >>> 2.20.1 >>> -- DENX Software Engineering GmbH, Managing Director: Johanna Denk, Tabea Lutz HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: +49-8142-66989-52 Fax: +49-8142-66989-80 Email: hs@denx.de
