Devices designed with Android in mind can have menu/home/back buttons in front face. In some devices these buttons are practically invisible unless the underlying button backlight is turned on. Add D-Bus interface that can used by applications and/or lipstick for requesting and tracking button backlight state. Implement policy that turns button backlight on when: - Related sysfs controls have been defined in mce configuration - At least one D-Bus client has requested backlight - Display is powered up - Lockscreen is not active Signed-off-by:
