2021-09-27soc: qcom: apr: Add GPR supportSrinivas Kandagatla
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 Kandagatla
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 Regno
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.

2021-08-04soc: qcom: smsm: Fix missed interrupts if state changes while maskedStephan Gerhold
The SMSM driver detects interrupt edges by tracking the last state it has seen (and has triggered the interrupt handler for). This works fine, but only if the interrupt does not change state while masked. For example, if an interrupt is unmasked while the state is HIGH, the stored last_value for that interrupt might still be LOW. Then, when the remote processor triggers smsm_intr() we assume that nothing has changed, even though the state might have changed from HIGH to LOW. Attempt to fix this by checking the current remote state before unmasking an IRQ. Use atomic operations to avoid the interrupt handler from interfering with the unmask function. This fixes modem crashes in some edge cases with the BAM-DMUX driver. Specifically, the BAM-DMUX interrupt handler is not called for the HIGH -> LOW smsm state transition if the BAM-DMUX driver is loaded (and therefore unmasks the interrupt) after the modem was already started: qcom-q6v5-mss 4080000.remoteproc: fatal error received: a2_task.c:3188: Assert FALSE failed: A2 DL PER deadlock timer expired waiting for Apps ACK Fixes: c97c4090ff72 ("soc: qcom: smsm: Add driver for Qualcomm SMSM") Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Link: https://lore.kernel.org/r/20210712135703.324748-2-stephan@gerhold.net Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2021-07-21bus: Make remove callback return voidUwe Kleine-König
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

2021-07-19soc: qcom: aoss: Fix the out of bound usage of cooling_devsManivannan Sadhasivam
In "qmp_cooling_devices_register", the count value is initially QMP_NUM_COOLING_RESOURCES, which is 2. Based on the initial count value, the memory for cooling_devs is allocated. Then while calling the "qmp_cooling_device_add" function, count value is post-incremented for each child node. This makes the out of bound access to the cooling_dev array. Fix it by passing the QMP_NUM_COOLING_RESOURCES definition to devm_kzalloc() and initializing the count to 0. While at it, let's also free the memory allocated to cooling_dev if no cooling device is found in DT and during unroll phase.

2021-07-19soc: qcom: rpmhpd: Use corner in power_offBjorn Andersson
rpmhpd_aggregate_corner() takes a corner as parameter, but in rpmhpd_power_off() the code requests the level of the first corner instead. In all (known) current cases the first corner has level 0, so this change should be a nop, but in case that there's a power domain with a non-zero lowest level this makes sure that rpmhpd_power_off() actually requests the lowest level - which is the closest to "power off" we can get. While touching the code, also skip the unnecessary zero-initialization of "ret".
