20 sda-gpios:
22 gpio used for the sda signal, this should be flagged as
24 from <dt-bindings/gpio/gpio.h> since the signal is by definition
28 scl-gpios:
30 gpio used for the scl signal, this should be flagged as
32 from <dt-bindings/gpio/gpio.h> since the signal is by definition
36 i2c-gpio,scl-output-only:

41 description: delay between GPIO operations (may depend on each platform)
43 i2c-gpio,timeout-ms:
50 description: sda and scl gpio, alternative for {sda,scl}-gpios
52 i2c-gpio,sda-open-drain:
56 the GPIO line used for SDA into open drain mode, and that something is
57 not the GPIO chip. It is essentially an inconsistency flag.
59 i2c-gpio,scl-open-drain:
63 GPIO line used for SCL into open drain mode, and that something is not
64 the GPIO chip. It is essentially an inconsistency flag.
