[PATCH v6 2/6] dt-bindings: ufs: qcom: Add ICE phandle

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Starting with SM8550, the ICE will have its own devicetree node
so add the qcom,ice property to reference it.

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

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
