soc: qcom: Add RPM processor/subsystem driverAdd a simple driver for the qcom,rpm-proc compatible that registers the"smd-edge" and populates other children defined in the device tree.Note that the DT schema belongs to the remoteproc subsystem while thisdriver is added inside soc/qcom. I argue that the RPM *is* a remoteproc,but as an implementation detail in Linux it can currently not benefitfrom anything provided by the remoteproc subsystem. The RPM firmware isusually already loaded and started by earlier components in the bootchain and is not meant to be ever restarted.To avoid breaking existing kernel configurations the driver is alwaysbuilt when smd-rpm.c is also built. They belong closely together anyway.To avoid build errors CONFIG_RPMSG_QCOM_SMD must be also built-in ifrpm-proc is.Reviewed-by: Konrad Dybcio Signed-off-by: Stephan Gerhold Link: https://lore.kernel.org/r/20230531-rpm-rproc-v3-9-a07dcdefd918@gerhold.netSigned-off-by: Bjorn Andersson List of files: /linux-6.15/drivers/soc/qcom/Makefile

Fri, 07 Apr 2023 10:50:26 +0000

soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driverThis takes the already existing duplicated support in both ufs-qcomand sdhci-msm drivers and makes it a dedicated driver that can be usedby both mentioned drivers.The reason for this is because, staring with SM8550, the ICE IP blockis shared between UFS and SDCC, which means we need to probe a dedicateddevice and share it between those two consumers.So let's add the ICE dedicated driver as a soc driver.Platforms that already have ICE supported, will use it as a libraryas the of_qcom_ice_get will return an ICE instance created for theconsumer device. This allows the backwards compatibility with old-styledevicetree approach.Also, add support to HW version 4.x since it works out-of-the-box withthe current driver.

Tue, 27 Dec 2022 15:22:46 +0000

soc: qcom: dcc: Add driver support for Data Capture and Compare unit(DCC)The DCC is a DMA Engine designed to capture and store dataduring system crash or software triggers. The DCC operatesbased on user inputs via the debugfs interface. The user givesaddresses as inputs and these addresses are stored in thedcc sram. In case of a system crash or a manual softwaretrigger by the user through the debugfs interface,the dcc captures and stores the values at these addresses.This patch contains the driver which has all the methodspertaining to the debugfs interface, auxiliary functions tosupport all the four fundamental operations of dcc namelyread, write, read/modify/write and loop. The probe methodhere instantiates all the resources necessary for dcc tooperate mainly the dedicated dcc sram where it stores thevalues. The DCC driver can be used for debugging purposeswithout going for a reboot since it can perform softwaretriggers as well based on user inputs.Also add the documentation for debugfs entries which explainsthe functionalities of each debugfs file that has been createdfor dcc.The following is the justification of using debugfs interfaceover the other alternatives like sysfs/ioctlsi) As can be seen from the debugfs attribute descriptions,some of the debugfs attribute files here contains multiplearguments which needs to be accepted from the user. This goesagainst the design style of sysfs.ii) The user input patterns have been made simple and convenientin this case with the use of debugfs interface as user doesn'tneed to shuffle between different files to execute one instructionas was the case on using other alternatives.Signed-off-by: Souradeep Chowdhury Reviewed-by: Alex Elder [bjorn: Fixed up a few indents and line wraps]Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/644b4f66a358492a8a6738454035c3b120092fe7.1672148732.git.quic_schowdhu@quicinc.com List of files: /linux-6.15/drivers/soc/qcom/Makefile

60f3692b - cpuidle: qcom_spm: Detach state machine from main SPM handling

cpuidle: qcom_spm: Detach state machine from main SPM handlingIn commit a871be6b8eee ("cpuidle: Convert Qualcomm SPM driver to a genericCPUidle driver") the SPM driver has been converted to ageneric CPUidle driver: that was mainly made to simplify thedriver 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 relatedstate machine (currently used only on ARM SoCs) stays there, whilethe SPM communication handling lands back in soc/qcom/spm.c andalso making sure to not discard the simplifications that wereintroduced in the aforementioned commit.Since now the "two drivers" are split, the SCM dependency in themain SPM handling is gone and for this reason it was also possibleto move the SPM initialization early: this will also make sure thatwhenever the SAW CPUIdle driver is getting initialized, the SPMdriver will be ready to do the job.Please note that the anticipation of the SPM initialization wasalso done to optimize the boot times on platforms that have theirCPU/L2 idle states managed by other means (such as PSCI), whileneeding SAW initialization for other purposes, like AVS control.Signed-off-by: AngeloGioacchino Del Regno Reviewed-by: Stephan Gerhold Tested-by: Stephan Gerhold Acked-by: Daniel Lezcano Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20210729155609.608159-2-angelogioacchino.delregno@somainline.org List of files: /linux-6.15/drivers/soc/qcom/Makefile
