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.

Merge tag 'qcom-drivers-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers More Qualcomm driver updates for 6.3 The qcom_scm.h file is moved into firmware/qcom, to avoid having any Qualcomm-specific files directly in include/linux. Support for PMIC GLINK is introduced, which on newer Qualcomm platforms provides an interface to the firmware implementing battery management and USB Type-C handling. Together with the base driver comes the custom altmode support driver. SMD RPM gains support for IPQ9574, and socinfo is extended with support for revision 17 of the information format and soc_id for IPQ5332 and IPQ8064 are added. The qcom_stats is changes not to fail when not all parts are initialized. * tag 'qcom-drivers-for-6.3-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: 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 soc: qcom: pmic_glink: Introduce base PMIC GLINK driver dt-bindings: soc: qcom: Introduce PMIC GLINK binding soc: qcom: dcc: Drop driver for now Link: https://lore.kernel.org/r/20230210182242.2023901-1-andersson@kernel.orgSigned-off-by: Arnd Bergmann <arnd@arndb.de>

Merge tag 'qcom-drivers-for-6.3' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.3 This introduces a new driver for the Data Capture and Compare block, which provides a mechanism for capturing hardware state (access MMIO registers) either upon request of triggered automatically e.g. upon a watchdog bite, for post mortem analysis. The remote filesystem memory share driver gains support for having its memory bound to more than a single VMID. The SCM driver gains the minimal support needed to support a new mechanism where secure world can put calls on hold and later request them to be retried. Support for the new SA8775P platform is added to rpmhpd, QDU1000 is added to the SCM driver and a long list of platforms are added to the socinfo driver. Support for socinfo data revision 16 is also introduced.

The dummy cycles value was wrongly calculated if dummy.buswidth > 1, which affects QSPI, OSPI, HyperFlash on various SoCs. We're lucky in Single SPI case since its dummy.buswidth equals to 1, so the result of the division is unchanged This issue can be reproduced using something like the following commands A. QSPI mode: Mount device with jffs2 format jffs2: CLEANMARKER node found at 0x00000004, not first node in block (0x00000000) B. QSPI mode: Write data to mtd10, where mtd10 is a parition on SPI Flash storage, defined properly in a device tree [Correct fragment, read from SPI Flash] root@v3x:~# echo "hello" > /dev/mtd10 root@v3x:~# hexdump -C -n100 /dev/mtd10 00000000 68 65 6c 6c 6f 0a ff ff ff ff ff ff ff ff ff ff |hello...........| 00000010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| [Incorrect read of the same fragment: see the difference at offsets 0-3] root@v3x:~# echo "hello" > /dev/mtd10 root@v3x:~# hexdump -C -n100 /dev/mtd10 00000000 00 00 00 00 68 65 6c 6c 6f 0a ff ff ff ff ff ff |....hello.......| 00000010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| As seen from the result, 4 NULL bytes were inserted before the test data. Wrong calculation in rpcif_prepare() led to miss of some dummy cycle. A division by bus width is redundant because it had been performed already in spi-rpc-if.c::rpcif_spi_mem_prepare() Fix this by removing the redundant division.

Add support for new field coming with socinfo structure under v17 to get hardware platform's oem variant id. This is to enable OEMs to have minor changes in the board, but to use the same platform subtype as the one supported by Qualcomm. The new field is to be used in platform overlay file. Default value is 0, reserved for Qualcomm platforms. Also, add debugfs support to read this field for a device.

This driver relies on SMEM to populate items for each subsystem before the device probes. 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.

With the PMIC GLINK service, the host OS subscribes to USB-C altmode messages, which are sent by the firmware to notify the host OS about state updates and HPD interrupts. The pmic_glink_altmode driver registers for these notifications and propagates the notifications as typec_mux, typec_switch and DRM OOB notifications as necessary to implement DisplayPort altmode support.

The PMIC GLINK service runs on one of the co-processors of some modern Qualcomm platforms and implements USB-C and battery managements. It uses a message based protocol over GLINK for communication with the OS, hence the name. 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.

As this is thightly coupled to the MT6357 PMIC, I took patches regarding it as well. * tag 'v6.2-next-soc' of https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux: (41 commits) soc: mediatek: mtk-svs: add missing MODULE_DEVICE_TABLE soc: mediatek: mtk-devapc: Switch to devm_clk_get_enabled() soc: mtk-svs: mt8183: refactor o_slope calculation soc: mediatek: mtk-svs: delete superfluous platform data entries soc: mediatek: mtk-svs: move svs_platform_probe into probe soc: mediatek: mtk-svs: improve readability of platform_probe soc: mediatek: mtk-svs: clean up platform probing soc: mediatek: mtk-svs: keep svs alive if CONFIG_DEBUG_FS not supported soc: mediatek: mtk-svs: Use pm_runtime_resume_and_get() in svs_init01() soc: mediatek: mtk-svs: reset svs when svs_resume() fail soc: mediatek: mtk-svs: restore default voltages when svs_init02() fail soc: mediatek: mmsys: add support for MT8195 VPPSYS dt-bindings: arm: mediatek: mmsys: Add support for MT8195 VPPSYS soc: mediatek: Introduce mediatek-regulator-coupler driver soc: mediatek: mtk-svs: Enable the IRQ later soc: mediatek: add mtk-mutex support for mt8195 vdosys1 soc: mediatek: add mtk-mutex component - dp_intf1 soc: mediatek: mmsys: add reset control for MT8195 vdosys1 soc: mediatek: mmsys: add mmsys for support 64 reset bits soc: mediatek: add cmdq support of mtk-mmsys config API for mt8195 vdosys1 ...

This driver does exactly devm_clk_get() and clk_prepare_enable() right after, which is exactly what devm_clk_get_enabled() does: clean that up by switching to the latter. This commit brings no functional changes.

If a compatible misses a match data entry, then something is wrong in the development phase, we don't need to check for that at runtime.
