These usually add support for additional chip variations in existing drivers, but also add features or bugfixes. The SCMI firmware subsystem gains a unified raw userspace interface through debugfs, which can be used for validation purposes. Newly added drivers include: - New power management drivers for StarFive JH7110, Allwinner D1 and Renesas RZ/V2M - A driver for Qualcomm battery and power supply status - A SoC device driver for identifying Nuvoton WPCM450 chips - A regulator coupler driver for Mediatek MT81xxv"* tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (165 commits) power: supply: Introduce Qualcomm PMIC GLINK power supply soc: apple: rtkit: Do not copy the reg state structure to the stack soc: sunxi: SUN20I_PPU should depend on PM memory: renesas-rpc-if: Remove redundant division of dummy soc: qcom: socinfo: Add IDs for IPQ5332 and its variant dt-bindings: arm: qcom,ids: Add IDs for IPQ5332 and its variant dt-bindings: power: qcom,rpmpd: add RPMH_REGULATOR_LEVEL_LOW_SVS_L1 firmware: qcom_scm: Move qcom_scm.h to include/linux/firmware/qcom/ MAINTAINERS: Update qcom CPR maintainer entry dt-bindings: firmware: document Qualcomm SM8550 SCM dt-bindings: firmware: qcom,scm: add qcom,scm-sa8775p compatible soc: qcom: socinfo: Add Soc IDs for IPQ8064 and variants dt-bindings: arm: qcom,ids: Add Soc IDs for IPQ8064 and variants soc: qcom: socinfo: Add support for new field in revision 17 soc: qcom: smd-rpm: Add IPQ9574 compatible soc: qcom: pmic_glink: remove redundant calculation of svid soc: qcom: stats: Populate all subsystem debugfs files dt-bindings: soc: qcom,rpmh-rsc: Update to allow for generic nodes soc: qcom: pmic_glink: add CONFIG_NET/CONFIG_OF dependencies soc: qcom: pmic_glink: Introduce altmode support ...

Support for socinfo data revision 16 is also introduced.Lastly a driver to program the ramp controller in MSM8976 is introduced.* tag 'qcom-drivers-for-6.3' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (33 commits) firmware: qcom: scm: Add wait-queue handling logic dt-bindings: firmware: qcom,scm: Add optional interrupt Revert "dt-bindings: power: rpmpd: Add SM4250 support" Revert "soc: qcom: rpmpd: Add SM4250 support" soc: qcom: socinfo: Add a bunch of older SoCs dt-bindings: arm: qcom,ids: Add a bunch of older SoCs dt-bindings: arm: qcom,ids: Add QRD board ID soc: qcom: socinfo: Fix soc_id order dt-bindings: soc: qcom: smd-rpm: Exclude MSM8936 from glink-channels dt-bindings: firmware: qcom: scm: Separate VMIDs from header to bindings soc: qcom: rmtfs: Optionally map RMTFS to more VMs dt-bindings: reserved-memory: rmtfs: Make qcom,vmid an array dt-bindings: firmware: scm: Add QDU1000/QRU1000 compatible dt-bindings: firmware: qcom,scm: narrow clocks and interconnects dt-bindings: firmware: qcom,scm: document MSM8226 clocks soc: qcom: ramp_controller: Make things static soc: qcom: rmphpd: add power domains for sa8775p dt-bindings: power: qcom,rpmpd: document sa8775p PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe() soc: qcom: dcc: rewrite description of dcc sysfs files ...Link: https://lore.kernel.org/r/20230126163008.3676950-1-andersson@kernel.orgSigned-off-by: Arnd Bergmann List of files: /linux/Documentation/ABI/testing/debugfs-driver-dcc

4cbe60cf5ad622f7f45ccc4fa369c9f7a71903b9 - soc: qcom: dcc: Add driver support for Data Capture and Compare unit(DCC)

Tue, 27 Dec 2022 16:22:46 +0100

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/Documentation/ABI/testing/debugfs-driver-dcc
