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

40   i2c-gpio,delay-us:
41     description: delay between GPIO operations (may depend on each platform)

52     description: sda and scl gpio, alternative for {sda,scl}-gpios
54   i2c-gpio,sda-open-drain:
58       the GPIO line used for SDA into open drain mode, and that something is
59       not the GPIO chip. It is essentially an inconsistency flag.
61   i2c-gpio,scl-open-drain:
65       GPIO line used for SCL into open drain mode, and that something is not
66       the GPIO chip. It is essentially an inconsistency flag.
