The OOB handling in the mxc_nand driver is broken for v1 type
controllers (i.MX27/31) with 512 byte page size. This perhaps
did not show up because ubi does not use OOB.
Update the driver to always read/write a whole page even if
only OOB is requested. With this patch the driver passes the
mtd_oobtest on i.MX27 with 512 byte page size. Also tested
with 2048 byte page size and on i.MX35 (v2 type controller)

This adds:
alias: devname:<name>
to some common kernel modules, which will allow the on-demand loading
of the kernel module when the device node is accessed.
Ideally all these modules would be compiled-in, but distros seems too
much in love with their modularization that we need to cover the common
cases with this new facility. It will allow us to remove a bunch of pretty
useless init scripts and modprobes from init scripts.
The static device node aliases will be carried in the module itself. The
program depmod will extract this information to a file in the module directory:
$ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname
# Device nodes to trigger on-demand module loading.
microcode cpu/microcode c10:184
fuse fuse c10:229
ppp_generic ppp c108:0
tun net/tun c10:200
dm_mod mapper/control c10:235
Udev will pick up the depmod created file on startup and create all the
static device nodes which the kernel modules specify, so that these modules
get automatically loaded when the device node is accessed:
$ /sbin/udevd --debug
...
static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184
static_dev_create_from_modules: mknod '/dev/fuse' c10:229
static_dev_create_from_modules: mknod '/dev/ppp' c108:0
static_dev_create_from_modules: mknod '/dev/net/tun' c10:200
static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235
udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666
udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666
A few device nodes are switched to statically allocated numbers, to allow
the static nodes to work. This might also useful for systems which still run
a plain static /dev, which is completely unsafe to use with any dynamic minor
numbers.
Note:
The devname aliases must be limited to the *common* and *single*instance*
device nodes, like the misc devices, and never be used for conceptually limited
systems like the loop devices, which should rather get fixed properly and get a
control node for losetup to talk to, instead of creating a random number of
device nodes in advance, regardless if they are ever used.
This facility is to hide the mess distros are creating with too modualized
kernels, and just to hide that these modules are not compiled-in, and not to
paper-over broken concepts. Thanks! :)

fb_defio: fix for non-dirty ptes
Fix a problem observed while using fb_defio with a short delay on a
PowerPC platform.
It is possible that page_mkclean() is invoked in the deferred io work
function _before_ a PTE has been marked dirty. In this case, the page is
removed from the defio pagelist but page_mkclean() does not write-protect
the page again. The end result is that defio ignores all subsequent
writes to the page and the corresponding portions of the framebuffer never
get updated.
The fix consists in keeping track of the pages with non-dirty PTEs,
re-checking them again on the next deferred io work iteration. Note that
those pages are not passed to the defio callback as they are not written
by userspace yet.

this is that the palette and data loading is now done in different
phases. And that the LCD must be disabled temporarily after the palette
is loaded but this will only happen once after init and each time the
palette is changed. I think this is OK.

rtc: use genirq directly in rtc-wm831x
Now that the WM831x core uses genirq for the IRQ controller there is no
need to use the WM831x-specific wrappers to request interrupts so convert
to use genirq directly.
Also use more meaningful strings to make /proc/interrupts more readily
legible.

rtc-cmos: do dev_set_drvdata() earlier in the initialization
The bug is an oops when dev_get_drvdata() returned null in
cmos_update_irq_enable(). The call tree looks like this:
rtc_dev_ioctl()
=> rtc_update_irq_enable()
=> cmos_update_irq_enable()
It's caused by a race condition in the module initialization. It is
rtc_device_register() which makes the ioctl operations live so I moved
the call to dev_set_drvdata() before the call to rtc_device_register().

rtc-ds1302: add some abstraction for new platform support
The current ds1302 driver (or at least the one that lives in /drivers/rtc)
seems to be designed for memory mapped devices only. This make it quite
hard to add support for GPIO-based implementations (as this is the case
for the upcoming Arcom Vulcan).
This patch moves the direct register access to inline functions with
explicit names. Still not as good as a proper platform driver, but at
least neater.

lis3: interrupt handlers for 8bit wakeup and click events
Content for the 8bit device threaded interrupt handlers. Depending on the
interrupt line and chip configuration, either click or wakeup / freefall
handler is called. In case of click, BTN_ event is sent via input device.
In case of wakeup or freefall, input device ABS_ events are updated
immediatelly.
It is still possible to configure interrupt line 1 for fast freefall
detection and use the second line either for click or threshold based
interrupts. Or both lines can be used for click / threshold interrupts.
Polled input device can be set to stopped state and still get coordinate
updates via input device using interrupt based method. Polled mode and
interrupt mode can also be used parallel.
BTN_ events are remapped based on existing axis remapping information.

lis3: introduce platform data for second ff / wu unit
8 bit device has two wakeup / free fall units. It was not possible to
configure the second unit. This patch introduces configuration entry to
the platform data and also corresponding changes to the 8 bit setup
function.
High pass filters were enabled by default. Patch introduces configuration
option for high pass filter cut off frequency and also possibility to
disable or enable the filter via platform data. Since the control is a
new one and default state was filter enabled, new option is used to
disable the filter. This way old platform data is still compatible with
the change.
