[PATCH v1 5/9] ARM: tegra: transformer: Add support for front camera

[Svyatoslav Ryhel]

Add front camera video path. Aptina MI1040 camera is used on all supported
ASUS Transformers, but only TF201 and TF700T will work since on
TF300T/TG/TL front camera is linked through an additional ISP.

[PATCH v1 6/9] ARM: tegra: transformers: Add connector node for common trees

[Svyatoslav Ryhel]

All ASUS Transformers have micro-HDMI connector directly available. After
Tegra HDMI got bridge/connector support, we should use connector framework
for proper HW description.
