Comment (by dangole):
Ok, this sets debounce for GPIOB 9 and GPIOB 10. The equivalent device-
tree snippet with the pinctrl section corresponding to the pins MF_B9 and
MF_B10 being GPIOs with debounce masked looks like this:
{{{
pinctrl {
i2c {
pinctrl_i2c: i2c-0 {
plxtech,pins =
<1 9 0 4 /* MF_B9 GPIO
debounce */
1 10 0 4>; /* MF_B10 GPIO
debounce *
};
};
};
i2c-gpio {
compatible = "i2c-gpio";
gpios = <&GPIOB 9 0 &GPIOB 10 0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c>;
i2c-gpio,delay-us = <10>;
#address-cells = <1>;
#size-cells = <0>;
ds1307: rtc@68 {
compatible = "dallas,ds1307";
reg = <0x68>;
};
};
}}}
