Just like the 353 series the underlying vendor is unknown/unmarked (at least not visible in a non-destructive manner). The panel had slightly different init sequences and timings in the BSP kernel, but works fine with the same ones used in the existing driver. The panel will not work without the inclusion of the MIPI_DSI_CLOCK_NON_CONTINUOUS flag, and this flag prevents the 353 series from working correctly, so a new compatible string is added. Tested colors and timings using modetest and all seem to work identical to the 353 otherwise.
