我配置m43x-epos-evm .dts  后是不成功的（I2C1不工作） 
            i2c1_pins: pinmux_i2c1_pins {                        pinctrl-single,pins = <
            0x158 (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE2)        /* i2c1_sda.i2c0_sda */
            0x15c (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE2)        /* i2c1_scl.i2c0_scl */
                        >;
                };


请问还要配置什么呢？
