It has nothing to do with touch hw though; it's just a way for us to get any OEM custom modes out of the VBT. For example on a given platform the VBT panel data may have a certain timing, but an additional timing may also be preferred, which might be specified in this block. So we should parse it, and add it to the appropriate connector's mode list. This patch only does the parsing, but doesn't add it to the mode list, so isn't useful by itself. At any rate, I'll drop it from this series. -- Jesse Barnes, Intel Open Source Technology Center
