This is for ChromeOS tablets which have a 'cros_cbas' switch device in the "Whiskers" base board. This device can be instantiated only by device tree on ARM platforms. ChromeOS EC doesn't provide a way to probe the device. Signed-off-by: Ikjoon Jang <ikjn@chromium.org> --- Changes in v5: - Add missing blank lines and change the description property's position. - Add a note to description: "this device cannot be detected at runtime." Changes in v4: Define cros-cbase bindings inside google,cros-ec.yaml instead of a separated binding document. .../bindings/mfd/google,cros-ec.yaml | 20 +++++++++++++++++++ 1 file changed, 20 insertions(+)
