[Linux-kernel-mentees] [PATCH 3/8] cec-follower: create digital ARIB channels

[Jiunn Chang]

This table will allow proper testing of digital tuner control features.
There are three channels per TSID/ONID/SID combination along with channel
data for the following digital ARIB broadcast systems:
  - ARIB-BS
  - ARIB-T
