Add binding documentation for i.MX8QXP and i.MX8QM ISI. The clock-names,
power-domains, and ports differ significantly from the existing
nxp,imx8-isi.yaml. Create a new file to avoid complex if-else branches.

Add new file to MAINTAINERS.

Hi Frank,

Thank you for the patch.

Mixed feelings about having different bindings files for what is
essentially the same IP, but I won't object.

This surprises me. The reference manual does list 8 clocks and
interrupts, but only 6 channels in the ISI section (for instance in
15.6.1.1.4). Which one is wrong ?

Figure 15-59 in the reference manual list MIPI CSI-2 RX 0 and RX 1 as
connected to inputs 0 and 1 respectively.

The memory map in the reference manual lists the "Pixel DMA" region as
ending at 0x5817ffff. Shouldn't the length of the region be 0x80000 ?

Here you have 5 channels, while the reference manual lists 8 interrupts
and 6 channels in the ISI documentation.

Table 15-6 in the reference manual lists the parallel port as input 4.

Should nxp,imx8-isi.yaml be renamed to fsl,imx8-isi.yaml ?

Rob suggest split it at v1.

https://lore.kernel.org/all/20250203221659.GA130749-robh@kernel.org/

"I think this addition is borderline whether it should be its own schema
doc. The if/then schemas are larger than the main part. The ports are
not even the same."

Support 6 input, 8 output.

"The crossbar is a 6 input 8 output multiplexer where each output port can
be configured to connect to any of the 6 inputs."

8 irq and clocks is for output dmac.

Reference document should be wrong, I reference another internal document

0: display control 0
1: display control 1
2: csi2 rx0
3: csi2 rx1
4: hdmi rx

Yes, it should be 0x80000.

QXP should only have 5 irqs and clocks. QM have 8, see above reply.

Suppose yes, it should match one of compatible string name. This patch
have not touch nxp,imx8-isi.yaml. we may rename it later
