Tuners are connected to demod I2C adapter. Use that muxed adapter
for each tuner. That allows us to get rid of hackish FE gate control
solution.

Own I2C locking is needed due to two special reasons:
1) Chips uses multiple register pages/banks on single I2C slave.
Page is changed via I2C register access.
2) Chip offers muxed/gated I2C adapter for tuner. Gate/mux is
controlled by I2C register access.
Due to these reasons, I2C locking did not fit very well.

The mmp ccic driver expects a platform_data structure that does not exist
in the mainline kernel and presumably was changed in a kernel fork, which
leads to build errors now:
media/platform/marvell-ccic/mmp-driver.c: In function 'mmpcam_calc_dphy':
media/platform/marvell-ccic/mmp-driver.c:252:15: error: 'struct mmp_camera_platform_data' has no member named 'dphy3_algo'

media/platform/marvell-ccic/mmp-driver.c:257:8: error: 'struct mmp_camera_platform_data' has no member named 'dphy'
This marks the driver as 'BROKEN' but keeps the code around.
Alternatively it could be removed entirely.

X-Patchwork-Delegate: m.chehab@samsung.com
As shown at the code, upd_demod_gain_period is used to write
to two 16-bit registers:
dib8000_write_word(state, 1946, upd_demod_gain_period & 0xFFFF);
dib8000_write_word(state, 1947, reg | (1<<14) | ((upd_demod_gain_period >> 16) & 0xFF));
So, it should be declared as u32.
This fixes the following smatch warning:

As reported by smatch:
drivers/media/pci/cx23885/cx23885-dvb.c:2080 dvb_register() Function too hairy. Giving up.
This is indeed a too complex function, with lots of stuff inside.

au0828_analog_register() frees au0828_dev when it fails to

and rc probe and registration assuming dev is still valid.
When au0828_analog_register() fails to locate isoc endpoint,
it should return without free'ing au0828_dev. Otherwise, the
probe will fail as dev is null when au0828_dvb_register() is

In fast switch mode the adv7180 (and similar) can lock onto a new signal
faster when switching between different inputs. As a downside though it is
no longer able to auto-detect the incoming format.
The fast switch mode is exposed as a boolean v4l control that allows
userspace applications to either enable or disable fast switch mode.

Some of the devices supported by this driver have a interlaced-to-
progressive converter which can optionally be enabled. This patch adds
support for enabling and disabling the I2P converter on such devices.
I2P mode can be enabled by selecting V4L2_FIELD_NONE instead of
V4L2_FIELD_INTERLACED for the format.

This patch adds support for the adv7280-m/adv2781-m/adv7281-ma/adv7282-m
devices to the adv7180 driver. They are very similar to the
adv7280/adv7281/adv7282 but instead of parallel video out they feature a
MIPI CSI2 transmitter.
The CSI2 transmitter is configured via a separate I2C address, so we need to
register a dummy device for it.
