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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The register state struct is 848 bytes, which ends up bloating the apple_rtkit_crashlog_dump_regs stack frame beyond 1024 on some 32-bit platforms, triggering compile warnings. This doesn't matter for 64BIT/ARM64, but there's also no good reason to copy the structure to the stack in this case. We can use __packed to avoid alignment issues, there are no double-read hazards, and this is a fatal error path so performance does not matter.

The items in SMEM that are being looked for are populated by the subsystems lazily, and therefore may not exist until the device has booted. For example, if I build this driver into the kernel on Trogdor Lazor and boot up, I don't see a 'modem' debugfs file populated, because the modem boots and populates the SMEM item after this driver probes. Always populate the files for the subsystems if they're in SMEM, and make the qcom_subsystem_sleep_stats_show() function return 0 if the SMEM items still isn't there. This way we can run a simple command like grep ^ /sys/kernel/debug/qcom_stats/* and collect the subsystem sleep stats without interspersed errors or missing details entirely because this driver probed first.

The driver implemented provides the rpmsg device for communication and uses auxiliary bus to spawn off individual devices in respective subsystem. The auxiliary devices are spawned off from a platform_device, so that the drm_bridge is available early, to allow the DisplayPort driver to probe even before the remoteproc has spun up.

The DCC operates based on user inputs via the debugfs interface. The user gives addresses as inputs and these addresses are stored in the dcc sram. In case of a system crash or a manual software trigger 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 methods pertaining to the debugfs interface, auxiliary functions to support all the four fundamental operations of dcc namely read, write, read/modify/write and loop. The probe method here instantiates all the resources necessary for dcc to operate mainly the dedicated dcc sram where it stores the values. The DCC driver can be used for debugging purposes without going for a reboot since it can perform software triggers as well based on user inputs. Also add the documentation for debugfs entries which explains the functionalities of each debugfs file that has been created for dcc. The following is the justification of using debugfs interface over the other alternatives like sysfs/ioctls i) As can be seen from the debugfs attribute descriptions, some of the debugfs attribute files here contains multiple arguments which needs to be accepted from the user. This goes against the design style of sysfs. ii) The user input patterns have been made simple and convenient in this case with the use of debugfs interface as user doesn't need to shuffle between different files to execute one instruction as was the case on using other alternatives.
