On the i.MX6SX there is a single entry for 'reg' and 'reg-names', so add
some logic to reflect that.

Can we drop the reg-names on MX6SX if we have reg maxItems=1 here ?

I think we can, but we need to retain that on the newer iMXes which have 
reg maxItems=2

Maybe this "fsl,imx6q-iomuxc-gpr" should be dropped here.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:
./Documentation/devicetree/bindings/display/bridge/fsl,ldb.yaml:84:12: [warning] wrong indentation: expected 10 but found 11 (indentation)

dtschema/dtc warnings/errors:

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230522125129.526604-1-festevam@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Cannot remove it as it breaks PCI:

imx6q-pcie 8ffc000.pcie: unable to find iomuxc registers
