Remove unnecessary references to i2c_attach_args::ia_prop and mark the ones
that remain as XXX.

Sync with HEAD.

fix proplib deprecation

Sync w/ HEAD.

iic_acquire_bus can fail.

don't prop_object_retain(NULL)

Sync with HEAD.

Use lmtemp(4) as entropy source.

- Add some additional compat strings from the DT bindings.
- Use device_compatible_entry::value to hold the device type, and generally
  tidy up device type selection.

If we're going to keep a reference on the "props" dictionary from
the i2c_attach_args, we should retain it.

Use DEVICE_COMPAT_EOL.

Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.

Use designated initializers and a consistent termination style in
compat_data[].

get sensor name from properties, remove macppc-specific OF support

moar match string

Sync with HEAD

In my quest to make device_compatible_entry (and associated goo)
super-general, it turns out I also made it a little to cumbersome
to use (if my tired fingers are any indication).  So, this is a
course-correction -- one string per entry (like of_compat_data,
which it will soon replace), and remove the over-verbose macros.

Sync with HEAD

- Rename iic_compat_match() to iic_compatible_match() and change it
  to use the new device_compatible_match() routine.  A pointer to
  the matching device_compatible_entry is returned if a match is
  found.
- Adjust iic_use_direct_match() accordingly.
- i2c drivers now provide device_compatible_entry tables when performing
  direct-config matching.
- In the dsrtc driver, take advantage of this new capability to greatly
  simplify model selection.

(I'm coming for you next, of_compat_data...)

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

attach to ds1775 which was already more or less supported as DS75
also, get sensor name/location from OpenFirmware if we know how

Sync with HEAD

Don't use I2C_F_POLL when getting/setting limits.
Save/restore the correct values for LM77.

Add display and setting of chip temperature limit(s) for envsys(4).

Read the Tos limit from the chip, instead of assuming 80'C, in case
firmware has altered it.  Make the *decode functions return temperatures
in either uK or C for envsys and sysctl, respectively.

Sync with HEAD (as of 26th Dec)

Direct config: Only match via the list of compatible hardware when we have
such a list available (ia_ncompat > 0). Otherwise fall back to matching
the device name with ia_name.

Resync to 2012-11-19 00:00:00 UTC

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

Add some pre-processor magic to verify that the type of the data item
  passed to sysctl_createv() actually matches the declared type for
  the item itself.
In the places where the caller specifies a function and a structure
  address (typically the 'softc') an explicit (void *) cast is now needed.
Fixes bugs in sys/dev/acpi/asus_acpi.c sys/dev/bluetooth/bcsp.c
  sys/kern/vfs_bio.c sys/miscfs/syncfs/sync_subr.c and setting
  AcpiGbl_EnableAmlDebugObject.
(mostly passing the address of a uint64_t when typed as CTLTYPE_INT).
I've test built quite a few kernels, but there may be some unfixed MD
  fallout. Most likely passing &char[] to char *.
Also add CTLFLAG_UNSIGNED for unsiged decimals - not set yet.

Support setting the temperature threshold for the LM75's alarm/interrupt
output. Some hardware ( I'm looking at you, Gdium ) abuses it to control
a fan.

Interpret them as such and simplify the conversion.

Extend the envsys2 API (one more time, sorry) as defined in:

http://mail-index.netbsd.org/tech-kern/2007/11/09/0001.html

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).

sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.

The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).

Update all users and documentation to reflect these changes.

Forgot to set the description in the sensor.

Sync with head.

There's no need to set the "envsys-description" property in the
driver's dictionary anymore, because with envsys2 you can change
descriptions.

Imported envsys 2, a brief description of the new features:
(Part 2: drivers)

* Support for detachable sensors.
* Cleaned up the API for simplicity and efficiency.
* Ability to send capacity/critical/warning events to powerd(8).
* Adapted all the code to the new locking order.
* Compatibility with the old envsys API: the ENVSYS_GTREINFO
  and ENVSYS_GTREDATA ioctl(2)s are supported.
* Added support for a 'dictionary based communication channel' between
  sysmon_power(9) and powerd(8), that means there is no 32 bytes event
  size restriction anymore.
* Binary compatibility with old envstat(8) and powerd(8) via COMPAT_40.
* All drivers with the n^2 gtredata bug were fixed, PR kern/36226.

file lm75.c was added on branch ktrace-lwp on 2004-08-03 10:46:06 +0000
