Nicolas below:-

'I would like to know what people think of the following patch.  It
allows for a codec on an AC97 bus to be shared with other drivers which
are completely unrelated to audio.  It registers a new bus type, and
whenever a codec instance is created then a device for it is also
registered with the driver model using that bus type.  This allows, for
example, to use the extra features of the UCB1400 like the touchscreen
interface and the additional GPIOs and ADCs available on that chip for
battery monitoring.  I have a working UCB1400 touchscreen driver here
that simply registers with the driver model happily working alongside
with audio features using this.'

Changes over RFC:-

  o Now matches codec name within codec group.
  o Added ac97_dev_release() to stop kernel complaining about no release
method for device.

19 years ago[CCID3]: Reorganise timeval handling
Arnaldo Carvalho de Melo [Sat, 27 Aug 2005 21:18:18 +0000 (18:18 -0300)]
[CCID3]: Reorganise timeval handling

Introducing functions to add to or subtract from a timeval variable
and renaming now_delta to timeval_new_delta that calls do_gettimeofday
and then timeval_delta, that should be used when there are several
deltas made relative to the current time or setting variables to it,
so as to avoid calling do_gettimeofday excessively.

I'm leaving these "timeval_" prefixed funcions internal to DCCP for a
while till we're sure there are no subtle bugs in it.

It also is more correct as it checks if the number of usecs added to
or subtracted from a tv_usec field is more than 2 seconds.

Michael Chan [Thu, 25 Aug 2005 22:35:24 +0000 (15:35 -0700)]
[BNX2]: speedup serdes linkup

This speeds up link-up time on 5706 SerDes if the link partner does
not autoneg, a rather common scenario in blade servers. Some blade
servers use IPMI for keyboard input and it's important to minimize
link disruptions.

The speedup is achieved by shortening the timer to (HZ / 3) during
the transient period right after initiating a SerDes autoneg. If
autoneg does not complete, parallel detect can be done sooner. After
the transient period is over, the timer goes back to its normal HZ
interval.

As suggested by Jeff Garzik, the timer initialization is moved to
bnx2_init_board() from bnx2_open().

An eeprom bit is also added to allow default forced SerDes speed for
even faster link-up time.

[BNX2]: Fix rtnl deadlock in bnx2_close

This fixes an rtnl deadlock problem when flush_scheduled_work() is
called from bnx2_close(). In rare cases, linkwatch_event() may be on
the workqueue from a previous close of a different device and it will
try to get the rtnl lock which is already held by dev_close().

The fix is to set a flag if we are in the reset task which is run
from the workqueue. bnx2_close() will loop until the flag is cleared.
As suggested by Jeff Garzik, the loop is changed to call msleep(1)
instead of yield() in the original patch.

flush_scheduled_work() is also moved to bnx2_remove_one() before the
netdev is freed.
