Subject: [media] media: rcar-vin: make V4L2_FIELD_INTERLACED standard dependent Author: Niklas Söderlund <niklas.soderlund+rene...@ragnatech.se> Date: Fri Sep 2 13:44:57 2016 -0300 The field V4L2_FIELD_INTERLACED is standard dependent and should not unconditionally be equivalent to V4L2_FIELD_INTERLACED_TB. This patch adds a check to see if the video standard can be obtained and if it's a 60 Hz format. If the condition is met V4L2_FIELD_INTERLACED is treated as V4L2_FIELD_INTERLACED_BT if not as V4L2_FIELD_INTERLACED_TB.
