	bool
	select RTC_LIB

menuconfig RTC_CLASS
	bool "Real Time Clock"
	default n
	depends on !S390
	select RTC_LIB
	help
	  Generic RTC class support. If you say yes here, you will
	  be allowed to plug one or more RTCs to your system. You will
	  probably want to enable one or more of the interfaces below.

if RTC_CLASS

config RTC_HCTOSYS
	bool "Set system time from RTC on startup and resume"
	default y
	help
	  If you say yes here, the system time (wall clock) will be set using
	  the value read from a specified RTC device. This is useful to avoid
	  unnecessary fsck runs at boot time, and to network better.

config RTC_HCTOSYS_DEVICE
	string "RTC used to set the system time"
	depends on RTC_HCTOSYS
	default "rtc0"
	help
	  The RTC device that will be used to (re)initialize the system
	  clock, usually rtc0. Initialization is done when the system
	  starts up, and when it resumes from a low power state. This
	  device should record time in UTC, since the kernel won't do
	  timezone correction.

	  This clock should be battery-backed, so that it reads the correct
	  time when the system boots from a power-off state. Otherwise, your
	  system will need an external clock source (like an NTP server).

	  If the clock you specify here is not battery backed, it may still
	  be useful to reinitialize system time when resuming from system
	  sleep states. Do not specify an RTC here unless it stays powered
	  during all this system's supported sleep states.

config RTC_SYSTOHC
	bool "Set the RTC time based on NTP synchronization"
	default y
	help
	  If you say yes here, the system time (wall clock) will be stored
	  in the RTC specified by RTC_HCTOSYS_DEVICE approximately every 11
	  minutes if userspace reports synchronized NTP status.

config RTC_SYSTOHC_DEVICE
	string "RTC used to synchronize NTP adjustment"
	depends on RTC_SYSTOHC
	default RTC_HCTOSYS_DEVICE if RTC_HCTOSYS
	default "rtc0"
	help
	  The RTC device used for NTP synchronization. The main difference
	  between RTC_HCTOSYS_DEVICE and RTC_SYSTOHC_DEVICE is that this
	  one can sleep when setting time, because it runs in the workqueue
	  context.

config RTC_DEBUG
	bool "RTC debug support"
	help
	  Say yes here to enable debugging support in the RTC framework
	  and individual RTC drivers.

config RTC_LIB_KUNIT_TEST
	tristate "KUnit test for RTC lib functions" if !KUNIT_ALL_TESTS
	depends on KUNIT
	default KUNIT_ALL_TESTS
	help
	  Enable this option to test RTC library functions.

	  If unsure, say N.

config RTC_NVMEM
	bool "RTC non volatile storage support"
	select NVMEM
	default RTC_CLASS
	help
	  Say yes here to add support for the non volatile (often battery
	  backed) storage present on RTCs.

config RTC_INTF_SYSFS
	bool "/sys/class/rtc/rtcN (sysfs)"
	depends on SYSFS
	default RTC_CLASS
	help
	  Say yes here if you want to use your RTCs using sysfs interfaces,
	  /sys/class/rtc/rtc0 through /sys/.../rtcN.

	  If unsure, say Y.

config RTC_INTF_PROC
	bool "/proc/driver/rtc (procfs for rtcN)"
	depends on PROC_FS
	default RTC_CLASS
	help
	  Say yes here if you want to use your system clock RTC through
	  the proc interface, /proc/driver/rtc.
	  Other RTCs will not be available through that API.
	  If there is no RTC for the system clock, then the first RTC(rtc0)
	  is used by default.

	  If unsure, say Y.

config RTC_INTF_DEV
	bool "/dev/rtcN (character devices)"
	default RTC_CLASS
	help
	  Say yes here if you want to use your RTCs using the /dev
	  interfaces, which "udev" sets up as /dev/rtc0 through
	  /dev/rtcN.

	  You may want to set up a symbolic link so one of these
	  can be accessed as /dev/rtc, which is a name
	  expected by "hwclock" and some other programs. Recent
	  versions of "udev" are known to set up the symlink for you.

	  If unsure, say Y.

config RTC_INTF_DEV_UIE_EMUL
	bool "RTC UIE emulation on dev interface"
	depends on RTC_INTF_DEV
	help
	  Provides an emulation for RTC_UIE if the underlying rtc chip
	  driver does not expose RTC_UIE ioctls. Those requests generate
	  once-per-second update interrupts, used for synchronization.

	  The emulation code will read the time from the hardware
	  clock several times per second, please enable this option
	  only if you know that you really need it.

config RTC_DRV_TEST
	tristate "Test driver/device"
	help
	  If you say yes here you get support for the
	  RTC test driver. It's a software RTC which can be
	  used to test the RTC subsystem APIs. It gets
	  the time from the system clock.
	  You want this driver only if you are doing development
	  on the RTC subsystem. Please read the source code
	  for further details.

	  This driver can also be built as a module. If so, the module
	  will be called rtc-test.

config RTC_DRV_AC100

	  This driver can also be built as a module. If so, the module
	  will be called rtc-ac100.

	  ST M41T00, EPSON RX-8025, Intersil ISL12057 and probably other chips.
	  In some cases the RTC must already have been initialized (by
	  manufacturing or a bootloader).

	  The first seven registers on these chips hold an RTC, and other
	  registers may add features such as NVRAM, a trickle charger for
	  the RTC/NVRAM backup power, and alarms. NVRAM is visible in
	  sysfs, but other chip features may not be available.
