f9228f4225 Add d_discard to all struct cdevsw instances I could find. 
All have been set to "nodiscard"; some should get a real implementation.

d70c01ba15 make implementation match gpio(4) man entry. do no change configuration 
if no flags are being set (allows non-destructive inquiry via GPIOSET again).

a68f9396b6 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.

the sysctl link sets are processed, and remove redundancy.

e21a34c25e 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.

d4bc0f70c1 gpiopwm(4) is a driver to pulse GPIO pins in software. This obsoletes 
the software pulsing facilities in gpio(4) (and gpioctl(8)) which will
later be removed.

90077b6e6d Add a ga_flags field to the gpio_attach structure to hand driver 
specific flags to drivers being attached at gpio pins.  gpioiic(4)
uses this to reverse the SDA/SCL signal order.  gpioctl(8) accepts
the flag values as optional argument to the attach command.
While here, make sure we retain backwards compatability and wrap compat
code in #ifdef COMPAT_50/#endif.

92ced822d1 Add a new ioctl, GPIOPULSE to gpio(4) to allow for pulsing a pin. 
If a pin can pulse in hardware, that will be used, else it will
be pulsed in software.  There is no way yet to set the pulse frequency
for pins that pulse in hardware.  While here, make the code mpsafe and
allow more than one thread in the driver (access to ioctl is serialized).

c1b390d493 A pointer typedef entails trading too much flexibility to declare const 
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

driver, gpiolock(4), is provided as an example how to interface real hardware.
A new securemodel, securemodel_keylock, is provided to show how this can
be used to tie keylocks to overall system security.  This is experimental
code.  The diff has been on tech-kern for several weeks.
