From 00f3bc2db351911700b3e951227e124a03b8a0bf Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Wed, 22 Feb 2023 19:22:35 +0200 Subject: [PATCH] dt-bindings: qcom-qce: Add new SoC compatible strings for Qualcomm QCE IP Introduce a generic IP family compatible 'qcom,qce' and its two derivatives based on SoC names rather than on IP versions. Having a generic compatible is only partially sufficient, the QCE IP version can be discovered in runtime, however there are two known groups of QCE IP versions, which require different DT properties, these two groups are populated with SoC based compatibles known at the moment. Keep the old compatible 'qcom,crypto-v5.1' and document an existing and already used but not previously documented compatible 'qcom,crypto-v5.4' for backward compatibility of DTB ABI, mark both of the compatibles as deprecated. The change is based on the original one written by Bhupesh Sharma, adding a generic family compatible is suggested by Neil Armstrong.
