[media] media: davinci: vpss: enable vpss clocks

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.

[media] media: davinci: kconfig: fix incorrect selects

drivers/media/platform/davinci/Kconfig uses selects where
it should be using 'depends on'. This results in warnings of
the following sort when doing randconfig builds.
warning: (VIDEO_DM6446_CCDC && VIDEO_DM355_CCDC && VIDEO_ISIF && VIDEO_DAVINCI_VPBE_DISPLAY) selects VIDEO_VPSS_SYSTEM which has unmet direct dependencies (MEDIA_SUPPORT && V4L_PLATFORM_DRIVERS && ARCH_DAVINCI)
The VPIF kconfigs had a strange 'select' and 'depends on' cross
linkage which have been fixed as well by removing unneeded
VIDEO_DAVINCI_VPIF config symbol.
Similarly, remove the unnecessary VIDEO_VPSS_SYSTEM and
VIDEO_VPFE_CAPTURE. They don't select any independent functionality
and were being used to manage code dependencies which can
be handled using makefile.
Selecting video modules is now dependent on all ARCH_DAVINCI
instead of specific EVMs and SoCs earlier. This should help build
coverage. Remove unnecessary 'default y' for some config symbols.
While at it, fix the Kconfig help text to make it more readable
and fix names of modules created during module build.
Rename VIDEO_ISIF to VIDEO_DM365_ISIF as per suggestion from
Prabhakar.
This patch has only been build tested; I have tried to not break
any existing assumptions. I do not have the setup to test video,
so any test reports welcome.

Chip id 18 is used by the em2710 and em2820.
The current code assumes that if the device is a camera, the chip is an em2710
and an em2820 otherwise.
But it turned out that the em2820 is also used in camera devices.
"Silvercrest 1.3 MPix" webcams for example are available with both chips.
Fortunately both variants are using different generic USD IDs which give us a

The get_rf_strength op in tuner-simple is valid only for the radio mode.
But due to the way get_signal in analog_demod_ops was designed it would

Pass a pointer to the signal value instead, and when not in radio mode
leave it alone in the tuner-simple.
This broke in commit 030755bde42bbed133182b0ece7c7a9c759478e8
(tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before
that this was working correctly. That commit did the right thing, but what

config looks like a hack that was added to tuner-core to allow some

But with the new configuration options of tda8290 driver (no_i2c_gate
and std_map), it's no longer sufficient.
Change config to be void * instead, which allows passing tuner-dependent

[media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
92002 does.

The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421
driver. In order to avoid regressions, the override is enabled
only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.

Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.
