d6cf3c637e FreeBSD, historically, has always used 8-bit addresses for i2c devices
(7-bit device address << 1), always leaving the room for the read/write bit.

This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses.  Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.

Also, update the PMIC i2c address on beaglebone* DTS files to match the new
address scheme.

Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).

a673123f8c Remove the unnecessary i2c slave address assignment.
The ti_i2c controller only works in the master mode and the i2c address
passed on iicbus_reset() is used to set the controller slave address when
operating as an i2c slave (which isn't currently supported).

When talking to a slave, the slave address is correctly provided to
ti_i2c_tranfer().

fcaf473cfc Overhaul CAM SG driver IOCTL interfaces.
Make it really work for native FreeBSD programs.  Before this it was broken
for years due to different number of pointer dereferences in Linux and
FreeBSD IOCTL paths, permanently returning errors to FreeBSD programs.
This change breaks the driver FreeBSD IOCTL ABI, making it more strict,
but since it was not working any way -- who bother.

Add shims for 32-bit programs on 64-bit host, translating the argument
of the SG_IO IOCTL for both FreeBSD and Linux ABIs.

With this change I was able to run 32-bit Linux sg3_utils tools and simple
32 and 64-bit FreeBSD test tools on both 32 and 64-bit FreeBSD systems.

62d76917b8 Introduce a procedural interface to the ifnet structure. The new
interface allows the ifnet structure to be defined as an opaque
type in NIC drivers.  This then allows the ifnet structure to be
changed without a need to change or recompile NIC drivers.

Put differently, NIC drivers can be written and compiled once and
be used with different network stack implementations, provided of
course that those network stack implementations have an API and
ABI compatible interface.

This commit introduces the 'if_t' type to replace 'struct ifnet *'
as the type of a network interface. The 'if_t' type is defined as
'void *' to enable the compiler to perform type conversion to
'struct ifnet *' and vice versa where needed and without warnings.
The functions that implement the API are the only functions that
need to have an explicit cast.

The MII code has been converted to use the driver API to avoid
unnecessary code churn. Code churn comes from having to work with
both converted and unconverted drivers in correlation with having
callback functions that take an interface. By converting the MII
code first, the callback functions can be defined so that the
compiler will perform the typecasts automatically.

As soon as all drivers have been converted, the if_t type can be
redefined as needed and the API functions can be fix to not need
an explicit cast.

The immediate benefactors of this change are:
1.  Juniper Networks - The network stack implementation in Junos
    is entirely different from FreeBSD's one and this change
    allows Juniper to build "stock" NIC drivers that can be used
    in combination with both the FreeBSD and Junos stacks.
2.  FreeBSD - This change opens the door towards changing ifnet
    and implementing new features and optimizations in the network
    stack without it requiring a change in the many NIC drivers
    FreeBSD has.

b1b4b37f4d Export two new settings for the AM335x PWM, the clock prescaler (clkdiv)
and the actual PWM frequency.

Enforce the maximum value for the period sysctl.

The frequency systcl now allows the direct setting of the PWM frequency (it
will try to find the better clkdiv and period for a given frequency, i.e.
the ones that will give the better PWM resolution).

This allows the use lower frequencies on the PWM.  Without changing the
clock prescaler the minimum PWM frequency was 1.52kHz.

PWM frequencies checked with an osciloscope.

PWM output tested with some R/C servos at 50Hz.

fb6bf8bba9 Glibc was switched to the FUTEX_WAIT_BITSET op and CLOCK_REALTIME
flag has been added instead of FUTEX_WAIT to replace the FUTEX_WAIT
logic which needs to do gettimeofday() calls before the futex syscall
to convert the absolute timeout to a relative timeout.
Before this the CLOCK_MONOTONIC used by the FUTEX_WAIT_BITSET op.

When the FUTEX_CLOCK_REALTIME is specified the timeout is an absolute
time, not a relative time. Rework futex_wait to handle this.
On the side fix the futex leak in error case and remove useless
parentheses.

Properly calculate the timeout for the CLOCK_MONOTONIC case.
