From 312416d9171a1460b7ed8d182b5b540c910ce80d Mon Sep 17 00:00:00 2001 From: Mahesh Sivasubramanian Date: Tue, 10 Apr 2018 11:57:23 -0600 Subject: drivers: qcom: add command DB driver Command DB is a simple database in the shared memory of QCOM SoCs, that provides information regarding shared resources. Some shared resources in the SoC have properties that are probed dynamically at boot by the remote processor. The information pertaining to the SoC and the platform are made available in the shared memory. Drivers can query this information using predefined strings.
