+* Sensor Controller\r
+\r
+Required properties:\r
+- compatible: the sensor name,exampel: "gs_mma8452";\r
+- reg: i2c slave address;\r
+- type: sensor type;\r
+- irq-gpio: sensor interrupt gpio pin;\r
+- irq_enable: 1 use irq; 0 use pull mode;\r
+- poll_delay_ms: pull delay time if use pull mode;\r
+- layout: sensor orientation, choose 1-8 to make product work fine;\r
