The name "cea_vendor_block" implies that it's a generic container for
vendor block encodings. Something more like:
struct cea_vendor_block_hdmi {
unsigned char portB:4;
unsigned char portA:4;
unsigned char portD:4:
unsigned char portC:4;
unsigned char support_flags;
unsigned char max_tmds_clock;
unsigned char latency_present;
unsigned char video_latency;
unsigned char audio_latency;
unsigned char interlaced_video_latency;
unsigned char interlaced_audio_latency;
};
/* other vendor block types */
struct cea_vendor_block {
unsigned char ieee_id[3];
union {
struct cea_vendor_block_hdmi hdmi;
/* any other vendor blocks we know about */
} u;
};
perhaps?
