rename davinci/ to ti/davinci/.

isif_probe() invokes iounmap() on error handling paths, but it does not
reset the global state. So, later it can invoke iounmap() even when
ioremap() fails. This is the case also for isif_remove(). The patch
resets the global state after invoking iounmap() to avoid this.

The isif_config_defaults structure is only copied into another
structure, so make it const.
The opportunity for this change was found using Coccinelle.

clang warns about a possible variable use that gcc never
complained about:
drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
[-Werror,-Wuninitialized]
dm365_vpss_set_pg_frame_size(frame_size);
^~~~~~~~~~
drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
struct vpss_pg_frame_size frame_size;
^
1 error generated.
There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.
On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.
To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

In isif_probe(), there is a while loop to get the ISIF base address and
linearization table0 and table1 address. In the loop body, the function
platform_get_resource() is called to get the resource. If
platform_get_resource() returns NULL, the loop is terminated and the
execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the
first iteration because platform_get_resource() returns NULL and the
execution goes to 'fail_nobase_res'. Given that there is another while loop
at 'fail_nobase_res' and i equals to 0, one iteration of the second while
loop will be executed. However, the second while loop does not check the
return value of platform_get_resource(). This can cause a NULL pointer
dereference bug if the return value is a NULL pointer.
This patch avoids the above issue by adding a check in the second while
loop after the call to platform_get_resource().

On all places, we do:

Here, it is doing, instead:
void * <asn_ref> foo;
That tricks static analyzers, making it see errors where
there's none. So, just reorder in order to cleanup those
warnings:

The only reason why this driver doesn't build with COMPILE_TEST
is because it includes mach/mux.h. It turns that none of the
macros defined there are used.
So, get rid of it, in order to allow it to build with
COMPILE_TEST.

By default the VPSS clocks were enabled in capture driver
for davinci family which creates duplicates for dm355/dm365/dm644x.
This patch adds support to enable the VPSS clocks in VPSS driver,
which avoids duplication of code and also adding clock aliases.
This patch uses PM runtime API to enable/disable clock, instead
of DaVinci clock framework. con_ids for master and slave clocks of
vpss is added in pm_domain.
This patch cleanups the VPSS clock enabling in the capture driver,
and also removes the clock alias in machine file. Along side adds
a vpss slave clock for DM365 as mentioned by Sekhar
(https://patchwork.kernel.org/patch/1221261/).
The Suspend/Resume in dm644x_ccdc.c which enabled/disabled the VPSS clock
is now implemented as part of the VPSS driver.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
