Merge tag 'soc-drivers-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
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 ...
