Hi:
   How / when does "ppc_md.set_rtc_time" get filled
in for Lite5200?

Config for support /dev/rtc enables CONFIG_PPC_RTC
which enable driver/char/rtc.c which mentions CMOS_WRITE
panics the kernel!

I trying to use driver/char/genrtc.c.   I can set date
but not hwclock.

 > hwclock --set --date="9/22/96 16:45:05"
gen_set_rtc_irq_bit:exit
gen_rtc_ioctl RTC_SET_TIME 00000060
RTC_SET_TIME: Invalid argument
ioctl() to /dev/rtc to set the time failed.

bash-2.05b# cat /proc/driver/rtc
rtc_time        : 00:50339648:36914
rtc_date        : -1072186980-497--1073718072
rtc_epoch       : 1900
alarm           : 00:00:00
DST_enable      : no
BCD             : yes
24hr            : yes
square_wave     : no
alarm_IRQ       : no
update_IRQ      : no  <----- how can I hook one?
periodic_IRQ    : no
periodic_freq   : 0
batt_status     : okay


thanks,

For 2.6 kernel, check arch/ppc/syslib/lite5200.c, especially
platform_init() (at the end of file).

Andrey:
    Thanks, sorry I forgot to mention I'm on DENX linuxppc_2_4_devel.
Where is the linuxppc 2.6.x distribution?
Is anyone maintaining a checklist of working features for imbedded 2.6?
Is this mail list searchable? (other than a month at a time?)

Merry Christmas
Frank Bennett

is this your point?
linux-2.6.12/arch/ppc/platforms/lite5200.c
      /* No time keeper on the LITE5200 */
    ppc_md.time_init    = NULL;
    ppc_md.get_rtc_time = NULL;
    ppc_md.set_rtc_time = NULL;

I don't see any arch/ppc/syslib/lite5200.c

Yes.

But, sorry, from which file are you quotating prev code ;)?

Check here http://www.denx.de/cgi-bin/gitweb.cgi?p=linux-2.6-denx.git

AFAIK - no. By very simple reason - all drivers in vanilla kernel MUST
be work, if some code not in Linus git, then it (usually) unstable or in
the pending stage.
