这里面的
pinctrl-single,pins：0x25C ， 0x188 。。。。这些地址如何得出；哪位帮忙解答一下
&am43xx_pinmux { pinctrl-names = "default", "sleep"; pinctrl-0 = <&ddr3_vtt_toggle_default &wlan_pins_default &debugss_pins &unused_pins>; pinctrl-1 = <&wlan_pins_sleep>; ddr3_vtt_toggle_default: ddr_vtt_toggle_default { pinctrl-single,pins = < 0x25C (DS0_PULL_UP_DOWN_EN | PIN_OUTPUT_PULLUP | DS0_FORCE_OFF_MODE | MUX_MODE7) /* spi0_cs0.gpio5_7 */ >; }; i2c0_pins: i2c0_pins { pinctrl-single,pins = < 0x188 (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE0) /* i2c0_sda.i2c0_sda */ 0x18c (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE0) /* i2c0_scl.i2c0_scl */ >; }; i2c1_pins_default: i2c1_pins_default { pinctrl-single,pins = < 0x15c (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE2) /* spi0_cs0.i2c1_scl */ 0x158 (PIN_INPUT_PULLUP | SLEWCTRL_FAST | MUX_MODE2) /* spi0_d1.i2c1_sda */ >; }; }
