Thank you for your patch. There is something to discuss/improve.

+  nuvoton,sar-threshold-num:
+    $ref: /schemas/types.yaml#/definitions/uint32
+    description:
+      Number of buttons supported.
+    minimum: 1
+    maximum: 4
+    default: 4

+  nuvoton,sar-threshold:
+    $ref: /schemas/types.yaml#/definitions/uint32-array
+    description:
+      Impedance threshold for each button. Array that contains up to 8 buttons
+      configuration. SAR value is calculated as
+      SAR = 255 * MICBIAS / SAR_VOLTAGE * R / (2000 + R) where MICBIAS is
+      configured by 'nuvoton,micbias-voltage', SAR_VOLTAGE is configured by
+      'nuvoton,sar-voltage', R - button impedance.
+      Refer datasheet section 10.2 for more information about threshold
+      calculation.
+    minItems: 1
+    maxItems: 4
Your description mentions 8 buttons, so maybe it should be 8 here? Or
description needs a fix?
Driver just handle maxima 4 buttons for general application, but the the
above description is truly hardware capability with 8 buttons support.
+    items:
+      minimum: 0

+  nuvoton,sar-hysteresis:

Best regards,
