	 * The AXP806 supports either master/standalone or slave mode.

	 * This is done with extra "serial interface address extension",
	 * or AXP806_BUS_ADDR_EXT, and "register address extension", or
	 * AXP806_REG_ADDR_EXT, registers. The former is read-only, with
	 * 1 bit customizable at the factory, and 1 bit depending on the
	 * state of an external pin. The latter is writable. The device
	 * will only respond to operations to its other registers when
	 * the these device addressing bits (in the upper 4 bits of the
	 * registers) match.
	 *
	 * By default we support an AXP806 chained to an AXP809 in slave
	 * mode. Boards which use an AXP806 in master mode can set the
	 * property "x-powers,master-mode" to override the default.
