2021-10-14soc: qcom: smem: Support reserved-memory descriptionBjorn Andersson1-18/+39
Practically all modern Qualcomm platforms has a single reserved-memory region for SMEM. So rather than having to describe SMEM in the form of a node with a reference to a reserved-memory node, allow the SMEM device to be instantiated directly from the reserved-memory node. The current means of falling back to dereferencing the "memory-region" is kept as a fallback, if it's determined that the SMEM node is a reserved-memory node. The "qcom,smem" compatible is added to the reserved_mem_matches list, to allow the reserved-memory device to be probed. In order to retain the readability of the code, the resolution of resources is split from the actual ioremapping.

2021-09-27soc: qcom: apr: Add GPR supportSrinivas Kandagatla2-7/+161
Qualcomm Generic Packet router aka GPR is the IPC mechanism found in AudioReach next generation signal processing framework to perform command and response messages between various processors. GPR has concepts of static and dynamic port, all static services like APM (Audio Processing Manager), PRM (Proxy resource manager) have fixed port numbers where as dynamic services like graphs have dynamic port numbers which are allocated at runtime. All GPR packet messages will have source and destination domain and port along with opcode and payload.

2021-09-27soc: qcom: apr: make code more reuseableSrinivas Kandagatla1-50/+79
APR and other packet routers like GPR are pretty much same and interact with other drivers in similar way. Ex: GPR ports can be considered as APR services, only difference is they are allocated dynamically. Other difference is packet layout, which should not matter with the apis abstracted. Apart from this the rest of the functionality is pretty much identical across APR and GPR. Make the apr code more reusable by abstracting it service level, rather than device level so that we do not need to write new drivers for other new packet routers like GPR. This patch is in preparation to add GPR support to this driver.

2021-09-21cpuidle: qcom_spm: Detach state machine from main SPM handlingAngeloGioacchino Del Regno3-0/+226
In commit a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a generic CPUidle driver") the SPM driver has been converted to a generic CPUidle driver: that was mainly made to simplify the driver and that was a great accomplishment; Though, at that time, this driver was only applicable to ARM 32-bit SoCs, lacking logic about the handling of newer generation SAW. In preparation for the enablement of SPM features on AArch64/ARM64, split the cpuidle-qcom-spm driver in two: the CPUIdle related state machine (currently used only on ARM SoCs) stays there, while the SPM communication handling lands back in soc/qcom/spm.c and also making sure to not discard the simplifications that were introduced in the aforementioned commit. Since now the "two drivers" are split, the SCM dependency in the main SPM handling is gone and for this reason it was also possible to move the SPM initialization early: this will also make sure that whenever the SAW CPUIdle driver is getting initialized, the SPM driver will be ready to do the job. Please note that the anticipation of the SPM initialization was also done to optimize the boot times on platforms that have their CPU/L2 idle states managed by other means (such as PSCI), while needing SAW initialization for other purposes, like AVS control.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.15 This fixes the "shared memory state machine" (SMSM) interrupt logic to avoid missing transitions happening while the interrupts are masked. SM6115 support is added to smd-rpm and rpmpd. The Qualcomm SCM firmware driver is once again made possible to compile and load as a kernel module. An out-of-bounds error related to the cooling devices of the AOSS driver is corrected. The binding is converted to YAML and a generic compatible is introduced to reduce the driver churn. The GENI wrapper gains a helper function used in I2C and SPI for switching the serial engine hardware to use the wrapper's DMA-engine. Lastly it contains a number of cleanups and smaller fixes for rpmhpd, socinfo, CPR, mdt_loader and the GENI DT binding. * tag 'qcom-drivers-for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: smsm: Fix missed interrupts if state changes while masked soc: qcom: smsm: Implement support for get_irqchip_state soc: qcom: mdt_loader: be more informative on errors dt-bindings: qcom: geni-se: document iommus soc: qcom: smd-rpm: Add SM6115 compatible soc: qcom: geni: Add support for gpi dma soc: qcom: geni: move GENI_IF_DISABLE_RO to common header PM: AVS: qcom-cpr: Use nvmem_cell_read_variable_le_u32() drivers: soc: qcom: rpmpd: Add SM6115 RPM Power Domains dt-bindings: power: rpmpd: Add SM6115 to rpmpd binding dt-bindings: soc: qcom: smd-rpm: Add SM6115 compatible soc: qcom: aoss: Fix the out of bound usage of cooling_devs firmware: qcom_scm: Allow qcom_scm driver to be loadable as a permenent module soc: qcom: socinfo: Don't print anything if nothing found soc: qcom: rpmhpd: Use corner in power_off soc: qcom: aoss: Add generic compatible dt-bindings: soc: qcom: aoss: Convert to YAML dt-bindings: soc: qcom: aoss: Add SC8180X and generic compatible firmware: qcom_scm: remove a duplicative condition firmware: qcom_scm: Mark string array const Link: https://lore.kernel.org/r/20210816214840.581244-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

In old variant irq_of_parse_and_map() returns zero if failed so unsigned int for virq_high/virq_low was ok. In new variant platform_get_irq() returns negative error codes if failed so we need to use int for virq_high/virq_low.

2021-08-12soc: renesas: Prefer memcpy() over strcpy()Len Baker2-4/+8
strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. So, use memcpy() as a safe replacement. This is a previous step in the path to remove the strcpy() function entirely from the kernel.

2021-08-10soc: ti: Remove pm_runtime_irq_safe() usage for smartreflexTony Lindgren1-30/+22
For the smartreflex device, we need to disable smartreflex on SoC idle, and have been using pm_runtime_irq_safe() to do that. But we want to remove the irq_safe usage as PM runtime takes a permanent usage count on the parent device with it. In order to remove the need for pm_runtime_irq_safe(), let's gate the clock directly in the driver. This removes the need to call PM runtime during idle, and allows us to switch to using CPU_PM in the following patch. Note that the smartreflex interconnect target module is configured for smart idle, but the clock does not have autoidle capability, and needs to be gated manually. If the clock supported autoidle, we would not need to even gate the clock. With this change, we can now remove the related quirk flags for ti-sysc also.
