I'm trying to set up i2c on the beaglebone black with a yocto build of
v3.19.3.
My dts contains
&i2c1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&i2c1_pins>;
clock-frequency = <100000>;
};
and ...
&am33xx_pinmux {
...
i2c1_pins: pin_mux_i2c1_pins {
pinctrl-single,pins = <
0x158 (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE2) /*
spi0_d1.i2c1_sda, P9_18 */
0x15C (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE2) /*
spi0_cs0.i2c1_scl, P9_17 */
>;
};
...
};
When I boot I get this error in the log
[ 1.506928] omap_i2c 44e0b000.i2c: could not find pctldev for node /
pinmux@44e10800/pinmux_i2c0_pins, deferring probe

How do I debug this error?
