X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5333a49e51c2d0d5fe1615f721898036733ed5b0;p=thirdparty%2Flinux.git

ARM: tegra: transformers: Add connector node for common trees

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.
