🫶 ARGUMENTS 🫶

• connector — a pointer to the connector you're allocating the codec for. this is the main character of the call fr fr 👑
• hdmi_codec_dev — the device that's gonna be used as the parent for the HDMI Codec. think of it as the parental supervision, very responsible of it 🧚
• funcs — the callbacks for this HDMI Codec. this is where you tell it how to actually behave 💅
• max_i2s_playback_channels — the maximum number of playback I2S channels. yes, maximum, not infinite, we are not gods 😭
• i2s_formats — the set of I2S formats. cute little detail: pass 0 if you want a bus-specific set 🌈
• spdif_playback — set this if the HDMI codec has an S/PDIF playback port. it's a bool, so like, yes or no, no in-between 🦋
• dai_port — the sound DAI port, and you pass -1 if it's not enabled. she's allowed to be off, we respect her boundaries 🙈
