[GIT PULL] drm/imx: imx-drm ldb and ipu-v3 csi fixes

[Philipp Zabel]

Hi Dave,

is there still room to get this into v4.18?

The LDB bind patch fixes a possible loss of LVDS display output on boot
on devices where the bootloader shows a splash screen and leaves the
display enabled. The CSI patch fixes interlaced capture from V4L2
subdevices that report V4L2_FIELD_ALTERNATE field order.

regards
Philipp

----------------------------------------------------------------
drm/imx: imx-drm ldb and ipu-v3 csi fixes

- Disable the LVDS Display Bridge (LDB) on driver bind. This is
  necessary to guarantee correct LVDS signals in case the bootloader
  left the LVDS output active.
- Remove false positive warning about disabled second LVDS channel in
  dual-channel mode. In this mode, the second LVDS channel can not be
  used separately. If the second channel is correctly described as
  disabled in the device tree, the driver warned about this anyway.
- Fix the CSI confiuration to not only enable interlaced capture mode
  for V4L2_FIELD_SEQ_BT and V4L2_FIELD_SEQ_TB, but also for the
  V4L2_FIELD_ALTERNATE interlacing mode. Before, it incorrectly tried
  to capture progressive frames in that case.
