Subject[PATCH v6 5/5] media: verisilicon: HEVC: Only propose 10 bitscompatible pixels formats
Date
When decoding a 10bits bitstreams HEVC 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.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")
