[PATCH v3 0/6] media: synopsys: Add imx93 support

[Frank Li]

This 3rd time try to support DW CSI2RX support for imx93.

1st: Create new dw csi2 driver
https://lore.kernel.org/all/20250701-95_cam-v1-5-c5172bab387b@xxxxxxx/

2nd: Based on legacy imx6's DW CSI2 constroller.
https://lore.kernel.org/imx/20250821-95_cam-v3-0-c9286fbb34b9@xxxxxxx/

Now rockchip create a common DW CSI2RX driver at
drivers/media/platform/synopsys/dw-mipi-csi2rx.c

This time base on rockchip's implement.

i.MX93's version is newer than rockchip one. i.MX6's is more similar with
rockchips.

But i.MX6 is too old. So start at i.MX93 firstly even it has bigger
difference.
