+Required properties:
+- compatible: must be "awinic,aw882xx_smartpa"
+- reg: Physical i2c address of the smartPA.
+- reset-gpio: reset pin of the smartPA.
+- irq-gpio: irq pin of the smartPA.
+
+- monitor-flag: low voltage and low temperature monitor control flag,
+    1: enable monitor,
+    0:disablemonitor.
+
+- monitor-timer-val: schedule duration of low voltage and low temperature monitor function, ms
+
+-low-vol-table-down:low voltage table of monitor when voltage is going down.
+    format:<voltage ipeak gain>
+
+-low-vol-table-up:low voltage table of monitor when voltage is going up.
+    format:<voltage ipeak gain>
+
+-low-temp-table-down:low temperature table of monitor when temperature is going down.
+    format:<temperature ipeak gain vmax>
+
+-low-temp-table-up:low temperature table of monitor when temperature is going up.
+    format:<temperature ipeak gain vmax>
+
+- afe-profile: music\voice\notification\ringtone profile setting in afe module,
+    1:enable param profile setting in afe
+    0:disable param profile setting in afe
+
+- afe-rx-portid: afe port id of I2S RX.
+- afe-tx-portid: afe port id of I2S TX.
