From: Paul Elder <paul.elder@ideasonboard.com>

The ISP supports both CSI and parallel interfaces, where port 0
corresponds to the former and port 1 corresponds to the latter. Since
the i.MX8MP's ISPs are connected by the parallel interface to the CSI
receiver, set them both to port 1.

Changes since v2:

- Assign clock parent and frequency in blk-ctrl

Changes since v1:

- Fix clock ordering
- Add #address-cells and #size-cells to ports nodes

Is the insertion of the extra <0> here correct?  You inserted one
clock above for IMX8MP_CLK_MEDIA_ISP, but it appears you inserted two
here.
I think this might break the IMX8MP_VIDEO_PLL1 rate and not set the
IMX8MP_CLK_MEDIA_ISP as expected.

Am I missing something?
