Subject[PATCH v6 2/6] dt-bindings: ufs: qcom: Add ICE phandle
Date
Starting with SM8550, the ICE will have its own devicetree node
so add the qcom,ice property to reference it.

Signed-off-by: Abel Vesa <abel.vesa@linaro.org>

The v5 is here:
https://lore.kernel.org/all/20230403200530.2103099-3-abel.vesa@linaro.org/

Changes since v5:
* dropped the sm8550 specific subschema and replaced it with one that
mutually excludes the qcom,ice vs both the ICE specific reg range
and the ICE clock

Changes since v4:
* Added check for sm8550 compatible w.r.t. qcom,ice in order to enforce
it while making sure none of the other platforms are allowed to use it

Changes since v3:
* dropped the "and drop core clock" part from subject line

Changes since v2:
* dropped all changes except the qcom,ice property
