| 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. |
| |
| The driver for this RTC device must be loaded before late_initcall |
| functions run, so it must usually be statically linked. |
| |
| 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 |

| RTC driver for the Atmel AT91SAM9x and AT91CAP9 internal RTT |
| (Real Time Timer). These timers are powered by the backup power |
| supply (such as a small coin cell battery), but do not need to |
| be used as RTCs. |
| |
| (On AT91SAM9rl chips you probably want to use the dedicated RTC |
| module and leave the RTT available for other uses.) |

| More than one RTT module is available. You can choose which |
| one will be used as an RTC. The default of zero is normally |
| OK to use, though some systems use that for non-RTC purposes. |

| help |
| The RTC driver needs to use one of the General Purpose Backup |
| Registers (GPBRs) as well as the RTT. You can choose which one |
| will be used. The default of zero is normally OK to use, but |
| on some systems other software needs to use that register. |

| config RTC_DRV_AU1XXX |
| tristate "Au1xxx Counter0 RTC support" |
| depends on SOC_AU1X00 |
| help |
| This is a driver for the Au1xxx on-chip Counter0 (Time-Of-Year |
| counter) to be used as a RTC. |
| |
| This driver can also be built as a module. If so, the module |
| will be called rtc-au1xxx. |

| config RTC_DRV_BFIN |
| tristate "Blackfin On-Chip RTC" |
| depends on BLACKFIN && !BF561 |
| help |
| If you say yes here you will get support for the |
| Blackfin On-Chip Real Time Clock. |
| |
| This driver can also be built as a module. If so, the module |
| will be called rtc-bfin. |

| # Please consider writing a new RTC driver instead of using the generic |
| # RTC abstraction |
| depends on PARISC || M68K || PPC || SUPERH32 |
| help |
| Say Y or M here to enable RTC support on systems using the generic |
| RTC abstraction. If you do not know what you are doing, you should |
| just say Y. |
| |
| config RTC_DRV_PXA |
| tristate "PXA27x/PXA3xx" |
| depends on ARCH_PXA |
| help |
| If you say Y here you will get access to the real time clock |
| built into your PXA27x or PXA3xx CPU. |
| |
| This RTC driver uses PXA RTC registers available since pxa27x |
| series (RDxR, RYxR) instead of legacy RCNR, RTAR. |
| |
| |
| config RTC_DRV_SUN4V |

| help |
| If you say Y here you will get support for the Hypervisor |
| based RTC on SUN4V systems. |
| |
| config RTC_DRV_STARFIRE |
| bool "Starfire RTC" |
| depends on SPARC64 |
| help |
| If you say Y here you will get support for the RTC found on |
| Starfire systems. |

| config RTC_DRV_MV |
| tristate "Marvell SoC RTC" |
| depends on ARCH_KIRKWOOD |
| help |
| If you say yes here you will get support for the in-chip RTC |
| that can be found in some of Marvell's SoC devices, such as |
| the Kirkwood 88F6281 and 88F6192. |
| |
| This driver can also be built as a module. If so, the module |
| will be called rtc-mv. |

| help |
| If you say yes here you will get support for the RTC on PS3. |
| |
| This driver can also be built as a module. If so, the module |
| will be called rtc-ps3. |
