config RTC_MC146818
	bool "Enable MC146818 driver"
	help
	  This is a widely used real-time clock chip originally by Motorola
	  and now available from NXP. It includes a battery-backed real-time
	  clock with a wide array of features and 50 bytes of general-purpose,
	  battery-backed RAM. The driver supports access to the clock and RAM.
