+description:
+  The Acer Aspire 1 laptop uses an embedded controller to control battery
+  and charging as well as to provide a set of misc features such as the
+  laptop lid status and HPD events for the USB Type-C DP alt mode.
+
+properties:
+  compatible:
+    const: acer,aspire1-ec
+
+  reg:
+    const: 0x76
+
+  interrupts:
+    maxItems: 1
+
+  acer,fn-selects-media-keys:
+    description: Configure the keyboard layout to invert the Fn key.
+      By default the function row of the keyboard inputs media keys
+      (i.e Vol-Up) when Fn is not pressed. With this option set, pressing
+      the key without Fn would input function keys (i.e. F11). The
+      firmware may choose to add this property when user selects the fn
+      mode in the firmware setup utility.
+    type: boolean
