+title: ChromeOS Hammer's Base Attached Switch
+
+maintainers:
+  - Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>
+
+description:
+  On some ChromeOS devices with a foldable variant of Hammer base, SW_TABLET_MODE
+  event should be generated with proper consideration of current device state.
+  This device senses "base attached" signal from EC (Embedded Controller)
+  and generates SW_TABLET_MODE event when Hammer is not attached.
+  The node for this device must be under a cros-ec node like google,cros-ec-spi
+  or google,cros-ec-i2c.
+
+properties:
+  compatible:
+   const: google,cros-cbas
+
+required:
+  - compatible
