This is a clean-up patch which replaces DEVICE_ATTR() macro with file

readability.

DEVICE_ATTR(attr, \(S_IRUGO\|0444\), show_fn, NULL);
@script: python p@

Snail address is subject to change, remove it completely from the code.
This has been done using the following script:
sed -i '/You should/,/02110-1301/d' \
$(git grep -n -w Franklin -- drivers/staging/media/atomisp/ | cut -f1 -d:)
No functional change intended.

This patch fixed comment style. Semantic should not be affected.
There are also two warnings left about too long lines, which
reduce readability if changed.

Return statement at the end of a void function is useless.
The Coccinelle semantic patch used to make this change is as follows:

hmm_init calls hmm_alloc to set dummy_ptr, hmm_alloc calls
hmm_init when dummy_ptr is not yet set, which is the case in
the call from hmm_init, so it calls hmm_init again, this continues
until we have a stack overflow due to the recursion.
This commit fixes this by adding a separate flag for tracking if
hmm_init has been called. Not pretty, but it gets the job done,
eventually we should be able to remove the hmm_init call from
hmm_alloc.

There's no need to check kmap() return value because it won't fail.
If it's highmem mapping, it will receive virtual address
or a new one; if it's lowmem, all kernel pages are already being mapped.

We don't need any of these indirections as we only support one MMU type. Start
by getting rid of the init/clear/free ones. The init ordering check we already
pushed down in a previous patch.
The allocation side is more complicated so leave it for now.

Currently the code handles this in the abstraction above. We want to remove
that abstraction so begin by pushing down the sanity check. Unfortunately
at this point we can't simply fix the init order.

We don't need an ifdef for the sake of 8-12 bytes. Avoid the ifdef added by
fde469701c7efabebf885e785edf367bfb1a8f3f. Instead turn it into a single const
string array at a fixed location thereby saving even more memory.

This reverts commit fde469701c7efabebf885e785edf367bfb1a8f3f.
Adding a preprocessor condition is not the best solution to fix this
issue. Let's revert this commit before fixing this problem in a more
appropriate way.

This is another define which is never used and references a header that doesn't
exist, so consider it dead. Our memcpy is pretty smart anyway.

Explicit type casting of variable, with same type as that of variable,
is not required. The following coccinelle script is used to remove it.

This patch adds support for the Intel IPU v2 as found on Android and IoT
Baytrail-T and Baytrail-CR platforms (those with the IPU PCI mapped). You
will also need the firmware files from your device (Android usually puts
them into /etc) - or you can find them in the downloadable restore/upgrade
kits if you blew them away for some reason.
It may be possible to extend the driver to handle the BYT/T windows
platforms such as the ASUS T100TA. These platforms don't expose the IPU via
the PCI interface but via ACPI buried in the GPU description and with the
camera information somewhere unknown so would need a platform driver
interface adding to the codebase *IFF* the firmware works on such devices.
To get good results you also need a suitable support library such as
libxcam. The camera is intended to be driven from Android so it has a lot of
features that many desktop apps don't fully spport.
In theory all the pieces are there to build it with -DISP2401 and some
differing files to get CherryTrail/T support, but unifying the drivers
properlly is a work in progress.
The IPU driver represents the work of a lot of people within Intel over many
years. It's historical goal was portability rather than Linux upstream. Any
queries about the upstream aimed driver should be sent to me not to the
original authors.
