Subject: [PATCH 02/14] dt-bindings: display: panel: allow ilitek,ili9341 in isolation

From: Conor Dooley <conor.dooley@microchip.com>

The dt-binding for the ilitek,ili9341 does not allow it to be used as a
compatible in isolation. This generates a warning for the Canaan kd233
devicetree:
arch/riscv/boot/dts/canaan/canaan_kd233.dtb: panel@0: compatible:0: 'ilitek,ili9341' is not one of ['st,sf-tc240t-9370-t']
        From schema: Documentation/devicetree/bindings/display/panel/ilitek,ili9341.yaml
arch/riscv/boot/dts/canaan/canaan_kd233.dtb: panel@0: compatible: ['ilitek,ili9341'] is too short
        From schema: Documentation/devicetree/bindings/display/panel/ilitek,ili9341.yaml
Allow ilitek,ili9341 to be selected in isolation.
