8:54 AM PT -- GaTa's lawyer Shawn Holley tells TMZ, "The entire incident between the parties is on video which I am in the process of providing to law enforcement. The video demonstrates clearly that Mr. Ganter did nothing wrong and, instead, tried to de-escalate the situation."

GaTa -- famous from the TV show 'Dave' -- was busted for domestic violence ... TMZ has learned.

Law enforcement sources tell us sheriff's deputies responded to a report of a DV incident in Santa Clarita, CA this past Sunday -- officers were told a physical argument occurred between two parties. The details are unclear ... but we know it ended with GaTa getting arrested.

We're told he was booked for felony domestic violence ... before being released on $100K bond and scheduled to appear in court at a later date. The case is under investigation.

GaTa -- whose real name is Davionte Ganter -- is a rapper/musician ... and lately, he's been an actor on Lil Dicky's FX series that launched in 2020 ... on which he's been featured for three seasons now, playing a fictionalized version of himself.

The guy is known in the music world ... having served as a professional hype man for the likes of Lil Wayne, Gym Class Heroes, Tyga and others.
