Tegra210 contains a powerful Video Input (VI) hardware controller
which can support up to 6 MIPI CSI camera sensors.
Each Tegra CSI port can be one-to-one mapped to VI channel and can
capture from an external camera sensor connected to CSI or from
built-in test pattern generator.
Tegra210 supports built-in test pattern generator from CSI to VI.
This patch adds a v4l2 capture driver with media interface for
Tegra210 built-in CSI to VI test pattern generator.
This patch includes TPG support only and all the video pipeline
configuration happens through the video device node.

With 'make menuconfig' I get this:
scripts/kconfig/mconf Kconfig
WARNING: unmet direct dependencies detected for TEGRA_HOST1X

This is an x86_64 build with COMPILE_TEST set. I can provide my full

Hi Hans,
In v7, changed Kconfig to remove ARM. But looks like we should limit
TEGRA_HOST1X also limits compile to ARM only so running VIDEO_TEGRA on
x86_64 shows above warning.
We should limit compile to ARM for CONFIG_VIDEO_TEGRA.
Will update CONFIG_VIDEO_TEGRA dependency to use ARM && COMPILE_TEST
like I had in previous version. Sorry about this.
Also, I see some changes went into latest linux-next staging media
Kconfig, So, will have my patches on top of today's linux-next.
VIDEO_TEGRA should depend on TEGRA_HOST1X and not select it.
depends on (ARCH_TEGRA && TEGRA_HOST1X) || COMPILE_TEST
Was selecting it to auto-select Tegra host1x when video_tegra is enabled.
Yes, can use depends on
