Subject: [PATCH] drm: add support for additional stereo 3D modes
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Parse the 3D_Structure_ALL and 3D_MASK fields of the HDMI Vendor
Specific Data Block to expose more stereo 3D modes.

v2: Use (1 << 0) for consistency. (Ville Syrjälä)
    Skip adding any modes if 3D_MASK is indicated as being present but
    the length only includes 3D_Structure_ALL. (Ville Syrjälä)
    Check that the value of HDMI_3D_LEN is large enough to include
    3D_Structure_ALL and 3D_MASK, if they are present. (Ville Syrjälä)
v3: Increment offset before the length checks. (Ville Syrjälä)
