Subject: media: dt-bindings: add NXP i.MX93 compatible string
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7425b2eaf50a90f57cde586a4a7a0e2e9c2fc0d1;p=thirdparty%2Fkernel%2Fstable.git

media: dt-bindings: add NXP i.MX93 compatible string

The i.MX93 uses the DW CSI-2 RX controller, which is similar to the
Rockchip RK3568 implementation.

The i.MX93 variant provides one IRQ, two clocks, and no resets. Add the
"fsl,imx93-mipi-csi2" compatible string and keep the same constraints for
RK3568.
