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.

run on the host CPU.
This approach allows to adapt the driver with a relatively small
effort should the Imaging Subsystem architecture change so that
the I2C bus is handled by the host's CPU OS, rather than the

Deal with this for v3.9 by reverting the problem commit, until folks can
figure out the right long-term course of action.

is going to be put into same directory. Hence we rename it to
exynos4-is as s5p-fimc was only relevant for early version of this
driver, when it only supported FIMC IP block.

The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will
be included in drivers/media/platform/exynos4-is directory, with some
modules shared with exynos5 series, while the rest of exynos5 specific
modules will find their home in drivers/media/platform/exynos5-is.
