Setting higher mclks seems to cause stability issues
on some R7 260X boards. Disable it for now for stability
until we find a proper fix.

PLLE has M, N and P divider shift and width parameters that differ from
the defaults. Furthermore, when clearing the M, N and P divider fields
the corresponding masks were never shifted, thereby clearing only the
lowest bits of the register. This lead to a situation where the PLLE
programming would only work if the register hadn't been touched before.

stripe count equals to 0 initially. Between atomic_inc and BUG_ON,
get_active_stripe() finds the stripe. So the stripe count isn't 1 any more.

At the moment the "Device Drivers / Graphics support" kernel config page
looks rather messy, with DRM and fbdev driver selections on the same
page, some on the top level Graphics support page, some under their
respective subsystems.
If I'm not mistaken, this is caused by the drivers depending on other
things than DRM or FB, which causes Kconfig to arrange the options in
not-so-neat manner.
Both DRM and FB have a main menuconfig option for the whole DRM or FB
subsystem. Optimally, this would be enough to arrange all DRM and FB
options under the respective subsystem, but for whatever reason this
doesn't work reliably.
This patch adds an explicit submenu for DRM and FB, making it much
clearer which options are related to FB, and which to DRM.

Instead of having fbdev framework core files at the root fbdev
directory, mixed with random fbdev device drivers, move the fbdev core
files to a separate core directory. This makes it much clearer which of
the files are actually part of the fbdev framework, and which are part
of device drivers.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

COMPILE_TEST allows us to build this driver on other arch'es. But not
all arch'es have the right I/O accessors -- particularly, x86 is missing
readsl() and writesl().
So just restrict this driver to ARCH_STI. It's still buildable for a
multiplatform ARM kernel, so it can get decent compile coverage.

Compile-testing for a 64-bit arch uncovers several bad casts:
In file included from include/linux/linkage.h:4:0,
from include/linux/kernel.h:6,
from drivers/mtd/devices/st_spi_fsm.c:15:
drivers/mtd/devices/st_spi_fsm.c: In function ‘stfsm_read_fifo’:

BUG_ON((((uint32_t)buf) & 0x3) || (size & 0x3));
...
Use uintptr_t instead of uint32_t, since it's guaranteed to be
pointer-sized.
We also see this warning, if size_t is not 32 bits wide:
In file included from drivers/mtd/devices/st_spi_fsm.c:15:0:
drivers/mtd/devices/st_spi_fsm.c: In function ‘stfsm_mtd_write’:

^
drivers/mtd/devices/st_spi_fsm.c:1704:11: note: in expansion of macro ‘min’
bytes = min(FLASH_PAGESIZE - page_offs, len);
^
Just use min_t() to force the type conversion, since we don't really
want to upgrade 'page_offs' and 'bytes' to size_t; they only should be
handling <= 256 byte offsets.

According to the Armada 370 and Armada XP datasheets, the part of the
Device Bus register that configure the bus width should contain 0 for
a 8 bits bus width, and 1 for a 16 bits bus width (other values are
unsupported/reserved).
However, the current conversion done in the driver to convert from a
bus width in bits to the value expected by the register leads to
setting the register to 1 for a 8 bits bus, and 2 for a 16 bits bus.
This mistake was compensated by a mistake in the existing Device Tree
files for Armada 370/XP platforms: they were declaring a 8 bits bus
width, while the hardware in fact uses a 16 bits bus width.
This commit fixes that by adjusting the conversion logic.
This patch fixes a bug that was introduced in
3edad321b1bd2e6c8b5f38146c115c8982438f06 ('drivers: memory: Introduce

In order to implement vb2 DVB support you need to be able to start
a kernel thread that queues and dequeues buffers, calling a callback
function for every buffer. This patch adds support for that.
It's based on drivers/media/v4l2-core/videobuf-dvb.c, but with all the DVB

Added a vb2_fileio_is_active inline function that returns true if fileio
is in progress. Check for this too in mmap() (you don't want apps mmap()ing
buffers used by fileio) and expbuf() (same reason).
In addition drivers should be able to check for this in queue_setup() to
return an error if an attempt is made to read() or write() with
V4L2_FIELD_ALTERNATE being configured. This is illegal (there is no way
to pass the TOP/BOTTOM information around using file I/O).
However, in order to be able to check for this the init_fileio function
needs to set q->fileio early on, before the buffers are allocated. So switch
to using internal functions (__reqbufs, vb2_internal_qbuf and
vb2_internal_streamon) to skip the fileio check. Well, that's why the internal
functions were created...
