I planned to set the polarity of horizontal and vertical sync, but
accidentally described vertical sync twice with different polarity
instead.

Note, that there is no functional change, because the driver only
makes use of DRM_MODE_FLAG_P[HV]SYNC to divert from the default
active-low polarity.

Is this panel somehow special with its NHSYNC / PVSYNC , compared to the other supported panels, which all use PHSYNC / PVSYNC ? I would expect all of these DSI TCON to use the same polarity, how come this one needs NHSYNC ?
