Subject: [PATCH v2 1/5] dt-bindings: arm: msm: Add llcc Broadcast_AND register region

The LLCC driver in SM8450, SM8550 and SM8650 have a new register
space for Broadcast_AND region. This is used to check that all
channels have bit set to "1", mainly in SCID activation/deactivation.

Previously we were mapping only the Broadcast_OR region assuming
there was only one broadcast register region. Now we also map
Broadcast_AND region.

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:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/cache/qcom,llcc.example.dtb: system-cache-controller@25000000: reg: [[0, 622854144, 0, 2097152], [0, 624951296, 0, 2097152], [0, 627048448, 0, 2097152], [0, 629145600, 0, 2097152], [0, 631242752, 0, 2097152]] is too short
from schema $id: http://devicetree.org/schemas/cache/qcom,llcc.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/53ba029fb1e3f66505b9f6487030e5d981e1621f.1707202761.git.quic_uchalich@quicinc.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.
