1dbae4c6cd iio:dac:ad5686: Add AD5681R/AD5682R/AD5683/AD5683R support
The AD5681R/AD5682R/AD5683/AD5683R are a family of one channel DACs with
12-bit, 14-bit and 16-bit precision respectively. The devices have either
no built-in reference, or built-in 2.5V reference.

These devices are similar to AD5691R/AD5692R/AD5693/AD5693R except
with a few notable differences:
 * they use the SPI interface instead of I2C
 * in the write control register, DB18 and DB17 are used for setting the
   power mode, while DB16 is the REF bit. This is why a new regmap type
   was defined and checked accordingly.
 * the shift register is 24 bits wide, the first four bits are the command
   bits followed by the data bits. As the data comprises of 20-bit, 18-bit
   or 16-bit input code, this means that 4 LSB bits are don't care. This is
   why the data needs to be shifted on the left with four bits. Therefore,
   AD5683_REGMAP is checked inside a switch case in the ad5686_spi_write()
   function. On the other hand, similar devices such as AD5693R family,
   have the 4 MSB command bits followed by 4 don't care bits.

These devices are pretty similar to AD5671R/AD5675R and
AD5694/AD5694R/AD5695R/AD5696/AD5696R, except that they have one channel.
Another difference is that they use a write control register(addr 0x04) for
setting the power down modes and the internal reference instead of separate
registers for each function.

4833dc4bb9 iio: tsl2583: correct values in integration_time_available
The times reported by the in_illuminance_integration_time_available
sysfs attribute are actually in milliseconds, not microseconds. This
patch corrects the times with the correct unit.

The fixes tag is inaccurate as the issue existed when the driver
was still in staging.   However, lots of changes occured before
it graduated so this is as a good a point as any for backports.

7cc31d57f3 staging: bcm2835-camera: Match MMAL buffer count to V4L2.
For historical reasons, the number of buffers passed to the VPU over
MMAL did not match that passed from V4L2.  That is a silly situation
as the driver has to duplicate serialisation and other functions that
have already been implemented in V4L2/videobuf2.

As we had more V4L2 buffers than MMAL ones, the MMAL buffer headers
were returned to the VPU immediately on being filled, which is now
invalid.

Match the number of buffers notified in queue_setup with that used in
MMAL.  Return buffers only when we get them from V4L2.

Interleaved RGB and single plane YUV formats can be delivered by the
GPU without the secondary step of removing padding, as the
bytesperline field can be set appropriately.

Planar YUV needs the GPU to still remove padding, as there is no way
to report that there is padding between the planes (ie on the height).
The multi-planar formats are NOT applicable, as there is no easy way
to make them contiguous in memory (ie one large allocation that gets
broken up). The whole task is passed across to videobuf2 which has no
notion of that requirement.

267d901a7d staging: lustre: o2iblnd: Enable Multiple OPA Endpoints between Nodes
OPA driver optimizations are based on the MPI model where it is
expected to have multiple endpoints between two given nodes. To
enable this optimization for Lustre, we need to make it possible,
via an LND-specific tuneable, to create multiple endpoints and to
balance the traffic over them.

Both sides of a connection must have this patch for it to work.
Only the active side of the connection (usually the client)
needs to have the new tuneable set > 1.
