ea959a70c5 Remove ONEWIRE_NOWAIT, it's unused now. 2007-09-05 15:39:22 +00:00

f5ad59004f onewire_lock: remove the flags argument and change the return type to void. 
This function is not expected to return an int, because rw_enter() will
always succeed.

933c2e67b5 Set the state on sc->sc_sensor[0].state and not append it, 
envsys2 doesn't use bits for the state member.

60ed581de9 There's no need to set the "envsys-description" property in the 
driver's dictionary anymore, because with envsys2 you can change
descriptions.

da3f163bd2 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.

Tested by:

bouyer: ipmi(4), mfi(4).
kefren: ug(4).
njoly: viaenv(4), adt7463.c.
riz: owtemp(4).
xtraeme: acpiacad(4), acpibat(4), acpitz(4), aiboost(4), it(4), lm(4).

fb44a8574b Remove the devprop API and switch everthing over to the new proplib. Add 
a new device_properties() accessor for device_t that returns the device's
property dictionary.

637bfc29f9 Dallas Semiconductor 1-Wire bus support, from OpenBSD. Currently includes 
gpioow(4), attaching a bit-banging driver via a GPIO pin.  Also,
owtemp(4) which supports some of the 1-Wire temperature sensors, including
the DS18b20 and DS1920 - temperatures are returned via the envsys(4)
framework.

Original drivers by Alexander Yurchenko (grange@openbsd), with envsys(4)
support and a fix to the 1-wire search algorithm (for discovering
devices on the bus) by me.

As discussed on tech-kern earlier this week.
