To support interlaced scan with planar formats, cpmem SLUV must
be programmed with the correct chroma line stride. For full and
partial planar 4:2:2 (YUV422P, NV16), chroma line stride must
be doubled. For full and partial planar 4:2:0 (YUV420, YVU420, NV12),
chroma line stride must _not_ be doubled, since a single chroma line
is shared by two luma lines.

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.

The IPUv3 can read 8-bit alpha values from a separate IDMAC channel driven

When disabling the foreground DP channel during a modeset, the DC is

Adds functions to link and unlink source channels to sink
channels in the FSU:
int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch);
int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch);
The channels numbers are usually IDMAC channels, but they can also be
channels that do not transfer data to or from memory. The following
convenience functions can be used in place of ipu_fsu_link/unlink()
when both source and sink channels are IDMAC channels:
int ipu_idmac_link(struct ipuv3_channel *src, struct ipuv3_channel *sink);
int ipu_idmac_unlink(struct ipuv3_channel *src, struct ipuv3_channel *sink);
So far the following links are supported:
IPUV3_CHANNEL_IC_PRP_ENC_MEM -> IPUV3_CHANNEL_MEM_ROT_ENC
PUV3_CHANNEL_IC_PRP_VF_MEM -> IPUV3_CHANNEL_MEM_ROT_VF
IPUV3_CHANNEL_IC_PP_MEM -> IPUV3_CHANNEL_MEM_ROT_PP
IPUV3_CHANNEL_CSI_DIRECT -> IPUV3_CHANNEL_CSI_VDI_PREV
More links can be added to the fsu_link_info[] array.

For all video modes we support currently, we always get 2 slots for
a plane by using the current existing dynamic DMFC FIFO allocation
mechanism. So, let's change to use the static one to simplify the
code. This also makes it easier to implement the atomic mode setting
as we don't need to handle allocation failure cases then.

The component master driver imx-drm-core matches component devices using
their of_node. Since commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc
module autoloading"), the imx-ipuv3-crtc dev->of_node is not set during
probing. Before that, of_node was set and caused an of: modalias to be
used instead of the platform: modalias, which broke module autoloading.
On the other hand, if dev->of_node is not set yet when the imx-ipuv3-crtc
probe function calls component_add, component matching in imx-drm-core
fails. While dev->of_node will be set once the next component tries to
bring up the component master, imx-drm-core component binding will never
succeed if one of the crtc devices is probed last.
Add of_node to the component platform data and match against the
pdata->of_node instead of dev->of_node in imx-drm-core to work around
this problem.

On some monitors, high resolution modes are not working, exhibiting
pixel column truncation problems (for example, 1280x1024 displays as
1280x1022).
The function ipu_di_adjust_videomode() aims to fix these issues by
adjusting a passed videomode to IPU restrictions. The function can
be called from the drm_crtc_helper_funcs->mode_fixup() methods.
