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.

drivers: qcom: rpmh-rsc: add RPMH controller for QCOM SoCs Add controller driver for QCOM SoCs that have hardware based shared resource management. The hardware IP known as RSC (Resource State Coordinator) houses multiple Direct Resource Voter (DRV) for different execution levels. A DRV is a unique voter on the state of a shared resource. A Trigger Control Set (TCS) is a bunch of slots that can house multiple resource state requests, that when triggered will issue those requests through an internal bus to the Resource Power Manager Hardened (RPMH) blocks. These hardware blocks are capable of adjusting clocks, voltages, etc. The resource state request from a DRV are aggregated along with state requests from other processors in the SoC and the aggregate value is applied on the resource. Some important aspects of the RPMH communication - - Requests are <addr, value> with some header information - Multiple requests (upto 16) may be sent through a TCS, at a time - Requests in a TCS are sent in sequence - Requests may be fire-n-forget or completion (response expected) - Multiple TCS from the same DRV may be triggered simultaneously - Cannot send a request if another request for the same addr is in progress from the same DRV - When all the requests from a TCS are complete, an IRQ is raised - The IRQ handler needs to clear the TCS before it is available for reuse - TCS configuration is specific to a DRV - Platform drivers may use DRV from different RSCs to make requests Resource state requests made when CPUs are active are called 'active' state requests. Requests made when all the CPUs are powered down (idle state) are called 'sleep' state requests. They are matched by a corresponding 'wake' state requests which puts the resources back in to previously requested active state before resuming any CPU. TCSes are dedicated for each type of requests. Active mode TCSes (AMC) are used to send requests immediately to the resource, while control TCS are used to provide specific information to the controller. Sleep and Wake TCS send sleep and wake requests, after and before the system halt respectively.

Support for communication with the hardened-RPM blocks in
Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
internal bus to transmit state requests for shared resources. A set
of hardware components aggregate requests for these resources and
help apply the aggregated state on the resource.
soc: qcom: rpmhpd: Add RPMh power domain driver The RPMh power domain driver aggregates the corner votes from various consumers for the ARC resources and communicates it to RPMh. With RPMh we use 2 different numbering space for corners, one used by the clients to express their performance needs, and another used to communicate to RPMh hardware. The clients express their performance requirements using a sparse numbering space which are mapped to meaningful levels like RET, SVS, NOMINAL, TURBO etc which then get mapped to another number space between 0 and 15 which is communicated to RPMh. The sparse number space, also referred to as vlvl is mapped to the continuous number space of 0 to 15, also referred to as hlvl, using command DB. Some power domain clients could request a performance state only while the CPU is active, while some others could request for a certain performance state all the time regardless of the state of the CPU. We handle this by internally aggregating the votes from both type of clients and then send the aggregated votes to RPMh. There are also 3 different types of votes that are comunicated to RPMh for every resource. 1. ACTIVE_ONLY: This specifies the requirement for the resource when the CPU is active 2. SLEEP: This specifies the requirement for the resource when the CPU is going to sleep 3. WAKE_ONLY: This specifies the requirement for the resource when the CPU is coming out of sleep to active state We add data for all power domains on sdm845 SoC as part of the patch.

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.
