Bhumika Goyal 0cba3f438c media: davinci: make ccdc_hw_device structures const
Make these structures const as they are only getting passed to the
functions vpfe_{register/unregister}_ccdc_device having the argument as
const.

Structures found using Coccinelle and changes done by hand.

Bhumika Goyal 1e6be01446 media: davinci: make function arguments const
Make the function arguments of functions vpfe_{register/unregister}_ccdc_device
const as the pointer dev does not modify the fields of the structure
it points to. Also, declare the variable ccdc_dev const as it points to the
same structure as dev but it does not modify the fields as well.

Jacob Chen 7bc9f038d0 media: i2c: OV5647: ensure clock lane in LP-11 state before streaming on
When I was supporting Rpi Camera Module on the ASUS Tinker board,
I found this driver have some issues with rockchip's mipi-csi driver.
It didn't place clock lane in LP-11 state before performing
D-PHY initialisation.

>From our experience, on some OV sensors,
LP-11 state is not achieved while BIT(5)-0x4800 is cleared.

So let's set BIT(5) and BIT(0) both while not streaming, in order to
coax the clock lane into LP-11 state.

0x4800 : MIPI CTRL 00
	BIT(5) : clock lane gate enable
		0: continuous
		1: none-continuous
	BIT(0) : manually set clock lane
		0: Not used
		1: used

Hans Verkuil 9d2d60687c media: tegra-cec: add Tegra HDMI CEC driver
This driver adds support for the Tegra CEC IP. It is based on the
NVIDIA drivers/misc/tegra-cec driver in their 3.10 kernel.

This has been converted to the CEC framework and cleaned up.

Tested with my Jetson TK1 board. It has also been tested with the
Tegra X1 in an embedded product.

Note of warning for the Tegra X2: this SoC supports two HDMI outputs,
but only one CEC adapter and the CEC bus is shared between the
two outputs. This is a design mistake and the CEC adapter can
control only one HDMI output. Never hook up both HDMI outputs
to the CEC bus in a hardware design: this is illegal as per the
CEC specification.

The CEC bus can be shared between multiple inputs and zero or one
outputs, but not between multiple outputs.
