Subject: [PATCH v9 6/6] media: verisilicon: VP9: Only propose 10 bits compatible pixels formats
Date:   Mon, 20 Feb 2023 11:48:49 +0100

When decoding a 10bits bitstreams VP9 driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.
