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).

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

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

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.
