Merge tag 'soc-drivers-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/socPull SoC driver updates from Arnd Bergmann: "The SoC driver changes once more consist of many small fixes and cleanups, that are to a large part the result of automated testing. On platform specific drivers, this includes SoC specific code for xilinx, freescale/nxp, qualcomm, TI, aspeed, omap, tegra, samsung, rockchip, renesas, ixp4xx. In firmware drivers, we see a similar picture for SCMI and qcomtee. Aside from these, we see actual new hardware support in a few areas: - The Apple platform gets a new driver for low power states - Updates to Qualcomm platform drivers add several new hardware specific features and additional SoCs. - Amlogic SoC support for A1 and T7 is added - The Mediatek MMSYS driver is refactored as a cleanup"* tag 'soc-drivers-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (157 commits) soc: qcom: make QCOM_PDR_MSG selectable soc: qcom: ubwc: Fix missing include soc: qcom: ubwc: Fix link error when QCOM_SMEM=n media: iris: Guard the QCOM_UBWC_CONFIG select with QCOM_SMEM drm/msm: Guard the QCOM_UBWC_CONFIG select with QCOM_SMEM dt-bindings: arm: qcom,ids: Add SoC ID for Snapdragon SDM 850 firmware: xilinx: Clear firmware notifiers across kexec transitions firmware: xilinx: Release all peripheral devices from firmware firmware: xilinx: Add support to clear EL3 PM state firmware: xilinx: Propagate actual error from feature check firmware: xilinx: Use TF-A feature check for TF-A-specific APIs bus: fsl-mc: drop unused assignment of acpi_device_id::driver_data soc: fsl: qe: check platform_driver_register() in qe_ic_of_init() phy: lynx-10g: use RCW override procedure for dynamic protocol change soc: fsl: guts: implement the RCW override procedure dt-bindings: fsl: layerscape-dcfg: define DCFG_DCSR region soc: fsl: guts: make fsl_soc_data available after fsl_guts_init() soc: fsl: guts: make it easier to determine on which SoC we are running soc: fsl: guts: add a central fsl_guts_read() function soc: fsl: guts: add a global structure to hold state ...

1d234eeafc56af8c9af6eee857f41a4310615e78 - soc: qcom: smem: Expose DDR data from SMEM

Mon, 27 Jul 2026 11:59:28 +0200

soc: qcom: smem: Expose DDR data from SMEMMost modern Qualcomm platforms (>= SM8150) expose information about theDDR memory present on the system via SMEM.Details from this information is used in various scenarios, such asmultimedia drivers configuring the hardware based on the "Highest Bankaddress Bit" (hbb), or the list of valid frequencies in validationscenarios...Add support for parsing v3-v7 version of the structs. Unforunately,they are not versioned, so some elbow grease is necessary to determinewhich one is present.
