Pull SoC driver updates from Arnd Bergmann: "The highlights for the driver support this time are - Qualcomm platforms gain support for the Qualcomm Secure Execution Environment firmware interface to access EFI variables on certain devices, and new features for multiple platform and firmware drivers. - Arm FF-A firmware support gains support for v1.1 specification features, in particular notification and memory transaction descriptor changes. - SCMI firmware support now support v3.2 features for clock and DVFS configuration and a new transport for Qualcomm platforms. - Minor cleanups and bugfixes are added to pretty much all the active platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and more. In particular, this contains portions of the treewide conversion to use __counted_by annotations and the device_get_match_data helper" * tag 'soc-drivers-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (156 commits) soc: qcom: pmic_glink_altmode: Print return value on error firmware: qcom: scm: remove unneeded 'extern' specifiers firmware: qcom: scm: add a missing forward declaration for struct device firmware: qcom: move Qualcomm code into its own directory soc: samsung: exynos-chipid: Convert to platform remove callback returning void soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size() soc: qcom: pmic_glink: fix connector type to be DisplayPort soc: ti: k3-socinfo: Avoid overriding return value soc: ti: k3-socinfo: Fix typo in bitfield documentation soc: ti: knav_qmss_queue: Use device_get_match_data() firmware: ti_sci: Use device_get_match_data() firmware: qcom: qseecom: add missing include guards soc/pxa: ssp: Convert to platform remove callback returning void soc/mediatek: mtk-mmsys: Convert to platform remove callback returning void soc/mediatek: mtk-devapc: Convert to platform remove callback returning void soc/loongson: loongson2_guts: Convert to platform remove callback returning void soc/litex: litex_soc_ctrl: Convert to platform remove callback returning void soc/ixp4xx: ixp4xx-qmgr: Convert to platform remove callback returning void soc/ixp4xx: ixp4xx-npe: Convert to platform remove callback returning void soc/hisilicon: kunpeng_hccs: Convert to platform remove callback returning void ...

bus: fsl-mc: Replace deprecated strncpy() with strscpy_pad()

2023-09-29T21:48:31Z

`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We need to prefer more robust and less ambiguous string interfaces. `obj_desc->(type|label)` are expected to be NUL-terminated strings as per "include/linux/fsl/mc.h +143" | ... | * struct fsl_mc_obj_desc - Object descriptor | * @type: Type of object: NULL terminated string | ... It seems `cmd_params->obj_type` is also expected to be a NUL-terminated string. A suitable replacement is `strscpy_pad` due to the fact that it guarantees NUL-termination on the destination buffer whilst keeping the NUL-padding behavior that `strncpy` provides. Padding may not strictly be necessary but let's opt to keep it as this ensures no functional change.

bus: vexpress-config: Annotate struct vexpress_syscfg_func with __counted_by

2023-09-25T18:38:27Z

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct vexpress_syscfg_func.

bus: ti-sysc: Fix SYSC_QUIRK_SWSUP_SIDLE_ACT handling for uart wake-up

2023-09-13T07:24:53Z

The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of SYSC_QUIRK_SWSUP_SIDLE_ACT. The difference is that SYSC_QUIRK_SWSUP_SIDLE is used to force idle target modules rather than block idle during usage. The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when a target module is active, and configure autoidle and wake-up when a target module is inactive. We are missing configuring the target module on sysc_disable_module(), and missing toggling of the wake-up bit. Let's fix the issue to allow uart wake-up to work.

bus: ti-sysc: Fix missing AM35xx SoC matching

2023-09-11T03:04:17Z

Commit feaa8baee82a ("bus: ti-sysc: Implement SoC revision handling") created a list of SoC types searching for strings based on names and wildcards which associates the SoC to different families. The OMAP34xx and OMAP35xx are treated as SOC_3430 while OMAP36xx and OMAP37xx are treated as SOC_3630, but the AM35xx isn't listed. The AM35xx is mostly an OMAP3430, and a later commit a12315d6d270 ("bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific") looks for the SOC type and behaves in a certain way if it's SOC_3430. This caused a regression on the AM3517 causing it to return two errors: ti-sysc: probe of 48318000.target-module failed with error -16 ti-sysc: probe of 49032000.target-module failed with error -16 Fix this by treating the creating SOC_AM35 and inserting it between the SOC_3430 and SOC_3630. If it is treaed the same way as the SOC_3430 when checking the status of sysc_check_active_timer, the error conditions will disappear.

bus: ti-sysc: Use fsleep() instead of usleep_range() in sysc_reset()

2023-09-11T03:04:17Z

The am335x-evm started producing boot errors because of subtle timing changes: Unhandled fault: external abort on non-linefetch (0x1008) at 0xf03c1010 ... sysc_reset from sysc_probe+0xf60/0x1514 sysc_probe from platform_probe+0x5c/0xbc ... The fix consists in using the appropriate sleep function in sysc reset. For flexible sleeping, fsleep is recommended. Here, sysc delay parameter can take any value in [0 - 255] us range. As a result, fsleep() should be used, calling udelay() for a sysc delay lower than 10 us.
