staging: add omapdrm DRM/KMS driver for TI OMAP platforms
A DRM display driver for TI OMAP platform. Similar to omapfb (fbdev)
and omap_vout (v4l2 display) drivers in the past, this driver uses the
DSS2 driver to access the display hardware, including support for
HDMI, DVI, and various types of LCD panels. And it implements GEM
support for buffer allocation (for KMS as well as offscreen buffers
used by the xf86-video-omap userspace xorg driver).
The driver maps CRTCs to overlays, encoders to overlay-managers, and
connectors to dssdev's. Note that this arrangement might change slightly
when support for drm_plane overlays is added.
For GEM support, non-scanout buffers are using the shmem backed pages
provided by GEM core (In drm_gem_object_init()). In the case of scanout
buffers, which need to be physically contiguous, those are allocated
with CMA and use drm_gem_private_object_init().
See userspace xorg driver:
git://github.com/robclark/xf86-video-omap.git

on 3.2-rc1, pull in private copies of drm_gem_{get,put}_pages()
because "drm/gem: add functions to get/put pages" patch is not
merged yet
v4: bit of rework of encoder/connector _dpms() code, modeset_init()
rework to not use nested functions, update TODO.txt
v3: minor cleanups, improved error handling for dev_load(), some minor
API changes that will be needed later for tiled buffer support
v2: replace omap_vram with CMA for scanout buffer allocation, remove
unneeded functions, use dma_addr_t for physical addresses, error
handling cleanup, refactor attach/detach pages into common drm
functions, split non-userspace-facing API into omap_priv.h, remove

staging:iio:treewide only use shared to decide on interfaces
Internally the fact that say scale is shared across channels is
actually of remarkably little interest. Hence lets not store it.
Numerous devices have weird combinations of channels sharing
scale anyway so it is not as though this was really telling
us much. Note however that we do still use the shared sysfs
attrs thus massively reducing the number of attrs in complex
drivers.
Side effect is that certain drivers that were abusing this
(mostly my work) needed to do a few more checks on what the
channel they are being queried on actually is.
This is also helpful for in kernel interfaces where we
just want to query the scale and don't care whether it
is shared with other channels or not.

iio/events.h for the event code stuff

is the stuff that userspace cares about.
Also include iio_event_type, iio_event_direction
Thus iio drivers include iio.h + as required
events.h
sysfs.h
buffer.h
in kernel users (once that interface is merged) will need inkern.h
which will pull in types.h
Userspace will need just events.h (which pulls in types.h) to get

Following the move to put the driver into one file, comments were added to identify which source file each set of functions originated from.
These no longer made sense after functions were moved around to remove some forward declarations, so remove them.
A function comment was previously not moved along with its function, now they are reunited.

staging: line6: alloc/free buffers in hw_params/hw_free
It is unsafe to free buffers in line6_pcm_stop(), which is not allowed
to sleep, since urbs cannot be killed completely there and only
unlinked. This means I/O may still be in progress and the URB
completion function still gets invoked. This may result in memory
corruption when buffer_in is freed but I/O is still pending.
Additionally, line6_pcm_start() is not supposed to sleep so it should
not use kmalloc(GFP_KERNEL).
These issues can be resolved by performing buffer allocation/freeing in
the .hw_params/.hw_free callbacks instead. The ALSA documentation also
recommends doing buffer allocation/freeing in these callbacks.

staging: line6: use smallest iso ep packet size
The POD HD300 isochronous endpoints have different max packet sizes for
read and write. Using the read endpoint max packet size may be too
large for the write endpoint. Instead we should use the minimum of both
endpoints to be sure the size is acceptable.
In theory we could decouple read and write packet sizes but the driver
currently uses a single size which I chose not to mess with since other
features like software monitoring may depend on a single packet size for
both endpoints.
