- Use todr_gettime_ymdhms / todr_settime_ymdhms.
- Correctly propagate errors up the stack.

No need to use I2C_F_POLL here.

Sync with HEAD

More cleanup to i2c autoconfiguration:

- Get all of the drivers onto the new match quality constants.
- Introduce a new helper function, iic_use_direct_match(), that has
  all of the logic for direct-config matching.  If it returns true,
  the driver returns the match result (which may be 0).  If it returns
  false, the driver does indirect-config matching.
- iic_compat_match() now returns a weighted match quality; matches to
  lower-indexed "compatible" device property are more-specific matches,
  and return a better match quality accordingly.

update from HEAD

Kill some more extern struct cfdriver declarations.

Down with externs in .c!

use the inline bcdtobin and bintobcd directly instead through a macro.

Rebase to HEAD as of a few days ago.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

sync with head

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

sync with head

Remove `volatile' qualifier from argument types of
struct timeval passed to todr_gettime(9) and todr_settime(9).
We no longer have an ancient and volatile struct timeval `time'
global since we have switched to MI timercounter(9) on all port.

XXX1: some of these RTC drivers still assume 32bit time_t
XXX2: some of these should be rewritten to use todr_[gs]ettime_ymdhms()
XXX3: todr(9) man page doesn't mention todr_[gs]ettime_ymdhms()

Re-add chunk of code that got lost in rev. 1.10. Makes this file build/work again. vi sometimes plays games with me. Spotted by dogcow.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

Fix the various todr_gettime() and todr_settime() fallouts from
-Wcast-qual differently, by instead changing the signatore of those
"functions" to take a "volatile struct timeval*" instead of a
"struct timeval*".  Many places, these functions are called with
&time, and time is declared as volatile in <sys/kernel.h>.  This
way we can get rid of all the ugly casts which now also triggered
warnings, and caused more code to be added to work around the
problem.

Adapt to branch.

PR kern/27088 from Jared Momose.  The read function should specify the
length of the command buffer (1) instead of 0.  Otherwise, data will
have an implied offset of 0 and reads at non-0 locations will incorrectly
return the data from 0.  Fix as suggested in the report.

Fix the sync with head I botched.

file m41t00.c was added on branch ktrace-lwp on 2004-08-03 10:46:06 +0000

As suggested by Jason Thorpe, rename m41t to m41trtc.

New generic I2C framework.  Supports bit-bang and "intelligent" I2C
interface controllers (of varying intelligence levels).
