Subject: [PATCH v2 2/2] soc: qcom: socinfo: Add support for new fields in revision 19
Date:   Tue, 6 Jun 2023 19:16:26 +0530
Message-ID: <20230606134626.18790-3-quic_namajain@quicinc.com>
In-Reply-To: <20230606134626.18790-1-quic_namajain@quicinc.com>

Precedence: bulk

Add support for below fields coming in socinfo structure under v19:
* num_func_clusters: number of clusters with at least one functional core
* boot_cluster: cluster selected as boot cluster
* boot_core: core selected as boot core
While at it, rename some variables to align them with their
functionalities.
