When detecting power failure, the probe function would reset the clock
time to defined state.However, the clock's _date_ might still be bogus and a subsequent probe
fails when sanity-checking these values.Change the power-failure fixup code to do a full setting of rtc_time,
including a valid date.Signed-off-by: Johannes Weiner

The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
tm_year is in years since 1900.The function translating rtc_time to register values assumes tm_year to be
years since first christmas, though, and we end up storing 0 or 1 in the
CCR_Y2K register, which the hardware does not refuse to do.A subsequent probing of the clock fails due to the invalid value range in
the register, though.[ And if it didn't, reading the clock would yield a bogus year because
the function translating registers to tm_year is assuming a register
value of 19 or 20. ]This fixes the conversion from years since 1900 in tm_year to the
corresponding CCR_Y2K value of 19 or 20.Signed-off-by: Johannes Weiner

I have discovered that the current version of rtc-x1205.c does not work
correctly when asked to set the alarm time by the RTC_WKALM_SET ioctl()
call. This happens because the alarm registers do not behave like the
current-time registers. They are non-volatile. Two things go wrong:- the X1205 requires a 10 msec delay after any attempt to write to the
non-volatile registers. The x1205_set_datetime() routine does the write
as 8 single-byte writes without any delay. Only the first write
succeeds. The second is NAKed because the chip is busy.- the X1205 resets the RWEL bit after any write to the non-volatile
registers. This would lock out any further writes after the first even
with a 10msec delay.I fix this by doing a single 8-byte write and then waiting 10msec for the
chip to be ready. A side effect of this change is that it will speed up
x1205_rtc_set_time() which uses the same code.I have also implemented the 'enable' bit in the rtc_wkalm structure, which
the existing driver does not attempt to do. I have modified both
x1205_rtc_set_alarm() to set the AL0E bit, and x1205_rtc_read_alarm() to
return it.I have tested this patch on a LinkSys NSLU2 under OpenWRT, but on no other
hardware. On the NSLU2 the X1205 correctly asserts its IRQ pin when the
alarm time matches the current time.[akpm@linux-foundation.org: clean up over-parenthesisation]

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.Signed-off-by: Jean Delvare

Based on earlier work by Jon Smirl and Jochen Friedrich.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.Signed-off-by: Jean Delvare

Update more I2C drivers that live outside drivers/i2c to understand that using
adapter->dev is not The Way. When actually referring to the adapter hardware,
adapter->class_dev.dev is the answer. When referring to a device connected to
it, client->dev.dev is the answer.Signed-off-by: David Brownell

A port of the existing x1205 driver under the new RTC subsystem.
It is actually under test within the NSLU2 project
(http://www.nslu2-linux.org) and it is working quite well.It is the first driver under this new subsystem and should be used as a guide
to port other drivers.Signed-off-by: Alessandro Zummo
