   4 Subject: [PATCH 35/75] omap3isp: Fix bad YUV_BT checks in datapath_config
   5
   6 The use of an external write enable signals (from ISP point of
   7 view) shouldn't depend on the sensor parallel interface type.
   8
   9 Also, the bit shift selection should NOT be other than 9_0 by
  10 default (i.e. No shift).
