Subject: [PATCH v2 1/4] dt-bindings: media: add i.MX parallel csi support
From: Alice Yuan <alice.yuan@....com>
Document the binding for parallel CSI controller found in i.MX8QXP, i.MX93
and i.MX91 SoCs.
Signed-off-by: Alice Yuan <alice.yuan@....com>
Signed-off-by: Frank Li <Frank.Li@....com>

Change in v2:
- use pcif surfix as Laurent Pinchart's suggest.
- put power-domains into required list

+title: i.MX8/9 Parallel Camera Interface
+
+maintainers:
+ - Frank Li <Frank.Li@....com>
+
+description: |
+ This is device node for the Parallel Camera Interface which enables the
+ chip to connect directly to external Parallel CMOS image sensors.
+ Supports up to 80MHz input clock from sensor.
+ Supports the following input data formats
+ - 8-bit/10-bit Camera Sensor Interface (CSI)
+ - 8-bit data port for RGB, YCbCr, and YUV data input
+ - 8-bit/10-bit data ports for Bayer data input
+ Parallel Camera Interface is hooked to the Imaging subsystem via the
+ Pixel Link.
