Subject: [PATCH 1/5] media: dt-bindings: nxp,imx8-isi: Add i.MX91 ISI
 compatible string

From: Alice Yuan <alice.yuan@....com>

The ISI module on i.MX91 is reused from i.MX93 and implements one channel
and one camera input which only can be connected to parallel camera input.
So needn't to select camera source like i.MX93 in gasket ops.
