2019-01-16media: gpu: ipu-csi: Swap fields according to input/output field typesSteve Longerbeam1-41/+85
The function ipu_csi_init_interface() was inverting the F-bit for NTSC case, in the CCIR_CODE_1/2 registers. The result being that for NTSC bottom-top field order, the CSI would swap fields and capture in top-bottom order. Instead, base field swap on the field order of the input to the CSI, and the field order of the requested output. If the input/output fields are sequential but different, swap fields, otherwise do not swap. This requires passing both the input and output mbus frame formats to ipu_csi_init_interface(). Move this code to a new private function ipu_csi_set_bt_interlaced_codes() that programs the CCIR_CODE_1/2 registers for interlaced BT.656 (and possibly interlaced BT.1120 in the future). When detecting input video standard from the input frame width/height, make sure to double height if input field type is alternate, since in that case input height only includes lines for one field.

2018-07-16gpu: ipu-v3: csi: support RGB565 on parallel busJan Luebbe1-4/+8
The CSI_SENS_CONF_DATA_FMT_RGB565 configuration only works for MIPI CSI-2 sources. On the parallel bus, we need to use bayer (generic) mode instead. To handle this difference, we pass the mbus_type to mbus_code_to_bus_cfg().
