Idle states have different enter/exit latency and residency values. +The idle states supported by the QCOM SoC are defined as - + + * Standby + * Retention + * Standalone Power Collapse (Standalone PC or SPC) + * Power Collapse (PC) + +Standby: Standby does a little more in addition to architectural clock gating. +When the WFI instruction is executed the ARM core would gate its internal +clocks. In addition to gating the clocks, QCOM cpus use this instruction as a +trigger to execute the SPM state machine. The SPM state machine waits for the +interrupt to trigger the core back in to active. This triggers the cache +hierarchy to enter standby states, when all cpus are idle. An interrupt brings +the SPM state machine out of its wait, the next step is to ensure that the +cache hierarchy is also out of standby, and then the cpu is allowed to resume +execution. This state is defined as a generic ARM WFI state by the ARM cpuidle +driver and is not defined in the DT. The SPM state machine should be +configured to execute this state by default and after executing every other +state below. + +Retention: Retention is a low power state where the core is clock gated and +the memory and the registers associated with the core are retained. The +voltage may be reduced to the minimum value needed to keep the processor +registers active. The SPM should be configured to execute the retention +sequence and would wait for interrupt, before restoring the cpu to execution +state. Retention may have a slightly higher latency than Standby. + +Standalone PC: A cpu can power down and warmboot if there is a sufficient time +between the time it enters idle and the next known wake up. SPC mode is used +to indicate a core entering a power down state without consulting any other +cpu or the system resources. This helps save power only on that core. The SPM +sequence for this idle state is programmed to power down the supply to the +core, wait for the interrupt, restore power to the core, and ensure the +system state including cache hierarchy is ready before allowing core to +resume. Applying power and resetting the core causes the core to warmboot +back into Elevation Level (EL) which trampolines the control back to the +kernel. Entering a power down state for the cpu, needs to be done by trapping +into a EL. Failing to do so, would result in a crash enforced by the warm boot +code in the EL for the SoC. On SoCs with write-back L1 cache, the cache has to +be flushed in s/w, before powering down the core. + +Power Collapse: This state is similar to the SPC mode, but distinguishes +itself in that the cpu acknowledges and permits the SoC to enter deeper sleep +modes. In a hierarchical power domain SoC, this means L2 and other caches can +be flushed, system bus, clocks - lowered, and SoC main XO clock gated and +voltages reduced, provided all cpus enter this state. Since the span of low +power modes possible at this state is vast, the exit latency and the residency +of this low power mode would be considered high even though at a cpu level, +this essentially is cpu power down. The SPM in this state also may handshake +with the Resource power manager (RPM) processor in the SoC to indicate a +complete application processor subsystem shut down. + +The idle-state for QCOM SoCs are distinguished by the compatible property of +the idle-states device node. + +The devicetree representation of the idle state should be - + +Required properties: + +- compatible: Must be one of - + "qcom,idle-state-ret", + "qcom,idle-state-spc", + "qcom,idle-state-pc", + and "arm,idle-state". + +Other required and optional properties are specified in [1]. + +Example: + + idle-states { + CPU_SPC: spc { + compatible = "qcom,idle-state-spc", "arm,idle-state"; + entry-latency-us = <150>; + exit-latency-us = <200>; + min-residency-us = <2000>; + }; + }; + +[1].

Most devicetree consumers (including the Linux +kernel) are not TrustZone aware and run entirely in either the Normal +world or the Secure world. However some devicetree consumers are +TrustZone aware and need to be able to determine whether devices are +visible only in the Secure address space, only in the Normal address +space, or visible in both. (One example of that situation would be a +virtual machine which boots Secure firmware and wants to tell the +firmware about the layout of the machine via devicetree.) + +The general principle of the naming scheme for Secure world bindings +is that any property that needs a different value in the Secure world +can be supported by prefixing the property name with "secure-". So for +instance "secure-foo" would override "foo". For property names with +a vendor prefix, the Secure variant of "vendor,foo" would be +"vendor,secure-foo". If there is no "secure-" property then the Secure +world value is the same as specified for the Normal world by the +non-prefixed property. However, only the properties listed below may +validly have "secure-" versions; this list will be enlarged on a +case-by-case basis. + +Defining the bindings in this way means that a device tree which has +been annotated to indicate the presence of Secure-only devices can +still be processed unmodified by existing Non-secure software (and in +particular by the kernel). + +Note that it is still valid for bindings intended for purely Secure +world consumers (like kernels that run entirely in Secure) to simply +describe the view of Secure world using the standard bindings. These +secure- bindings only need to be used where both the Secure and Normal +world views need to be described in a single device tree. + +Valid Secure world properties +----------------------------- + +- secure-status : specifies whether the device is present and usable + in the secure world. The combination of this with "status" allows + the various possible combinations of device visibility to be + specified. If "secure-status" is not specified it defaults to the + same value as "status"; if "status" is not specified either then + both default to "okay". This means the following combinations are + possible: + + /* Neither specified: default to visible in both S and NS */ + secure-status = "okay"; /* visible in both */ + status = "okay"; /* visible in both */ + status = "okay"; secure-status = "okay"; /* visible in both */ + secure-status = "disabled"; /* NS-only */ + status = "okay"; secure-status = "disabled"; /* NS-only */ + status = "disabled"; secure-status = "okay"; /* S-only */ + status = "disabled"; /* disabled in both */ + status = "disabled"; secure-status = "disabled"; /* disabled in both */ + +The secure-chosen node +---------------------- + +Similar to the /chosen node which serves as a place for passing data +between firmware and the operating system, the /secure-chosen node may +be used to pass data to the Secure OS. Only the properties defined +below may appear in the /secure-chosen node. + +- stdout-path : specifies the device to be used by the Secure OS for + its console output. The syntax is the same as for /chosen/stdout-path. + If the /secure-chosen node exists but the stdout-path property is not + present, the Secure OS should not perform any console output. If + /secure-chosen does not exist, the Secure OS should use the value of + /chosen/stdout-path instead (that is, use the same device as the + Normal world OS). diff --git a/Documentation/devicetree/bindings/arm/socionext/milbeaut.yaml b/Documentation/devicetree/bindings/arm/socionext/milbeaut.yaml new file mode 100644 index 000000000..5a428a885 --- /dev/null +++ b/Documentation/devicetree/bindings/arm/socionext/milbeaut.yaml @@ -0,0 +1,25 @@ +# SPDX-License-Identifier: GPL-2.0 +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/arm/socionext/milbeaut.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Milbeaut platforms + +maintainers: + -
