ASoC: samsung: Expand odroidx2 compatible of match table

This patch updates the compatible match table for odroid.
Since the machine driver is not only used on odroidx2 board,
but is also used on odroidu3 board, so it's better to expand
the compatible match table string for compatibility concern.

upstream: [media] au0828: reset streaming when a new frequency is set

As reported by Trevor, doing several opening/streaming/closing
operations to the demux causes it to fail.

I was able to simulate this bug too. I also noticed that,
sometimes, changing channels with au0828, the same thing
happens.

Most of the issues seem to be due to some hardware bug, that
causes the device to not fill all the URBs allocated. When
the bug happens, the only known fix is to either replug the
device, or to send an USB reset to it.

There's also a hack a the au0828 driver that starts a thread
that tries to reset the device when a package doesn't start
with a sync.

One of the culpits for this bad hardware behavior seem to be
caused by the lack of stopping and restarting the stream every
time a new channel is set.

This patch warrants that the stream will be properly reset
every time the set_frontend callback is called, partially
solving the problem.

A complete fix, however, would also need to check the PM
conditions for the tuner and demux.

resolution change detected by a video decoder OR a format change
detected by an input connector.

upstream: [media] ARM: S5PV210: Remove camera support from mach-goni.c

S5PV210 is going to get DT support, so we can remove the camera
bits from the only board using camera on S5PV210. This allows to
clean the exynos4-is driver by dropping code for non-dt platforms.
This patch can be dropped if a patch removing the whole board
file is applied first.

There are no need to store resource struct and IRQ in the driver
internal structure.
This patch remove these fields and improve error handling by using
proper return codes from devm_ioremap_resource() and devm_request_irq().

upstream: [media] mt9p031: Fix BLC configuration restore when disabling test pattern

Auto BLC and BLC digital offset are disabled when enabling the test
pattern and must be restored when disabling it. The driver does so by
calling the set control handler on the auto BLC and BLC offset controls,
but this programs the hardware with the new value of those controls, not
the current value. Fix this by writing to the registers directly.

upstream: [media] mt9p031: Really disable Black Level Calibration in test pattern mode

The digital side of the Black Level Calibration (BLC) function must be
disabled when generating a test pattern to avoid artifacts in the image.
The driver disables BLC correctly at the hardware level, but the feature
gets reenabled by v4l2_ctrl_handler_setup() the next time the device is
powered on.

Fix this by marking the BLC controls as inactive when generating a test
pattern, and ignoring control set requests on inactive controls.
