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.

ARM: qcom: Add Subsystem Power Manager (SPM) driver SPM is a hardware block that controls the peripheral logic surrounding the application cores (cpu/l$). When the core executes WFI instruction, the SPM takes over the putting the core in low power state as configured. The wake up for the SPM is an interrupt at the GIC, which then completes the rest of low power mode sequence and brings the core out of low power mode. The SPM has a set of control registers that configure the SPMs individually based on the type of the core and the runtime conditions. SPM is a finite state machine block to which a sequence is provided and it interprets the bytes and executes them in sequence. Each low power mode that the core can enter into is provided to the SPM as a sequence. Configure the SPM to set the core (cpu or L2) into its low power mode, the index of the first command in the sequence is set in the SPM_CTL register. When the core executes ARM wfi instruction, it triggers the SPM state machine to start executing from that index. The SPM state machine waits until the interrupt occurs and starts executing the rest of the sequence until it hits the end of the sequence. The end of the sequence jumps the core out of its low power mode. Add support for an idle driver to set up the SPM to place the core in Standby or Standalone power collapse mode when the core is idle.

soc: qcom: smd: Transition client drivers from smd to rpmsg By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client drivers in one commit, to make sure we have a working system before and after this transition.
