Merge tag 'soc-drivers-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2026-08-19T02:40:29+00:00

Pull 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"

dt-bindings: sram: qcom,imem: Add minidump-sram pattern property

2026-07-30T22:05:46+00:00

The qcom,imem binding describes a single word in always-on SRAM shared
between the operating system (OS) and boot firmware. Before DDR is
initialized on the warm reset following a crash, firmware reads this
word to decide where to deliver the minidump, and the OS is expected to
select one of the destinations: either USB upload to a host PC or save
to on-device storage. If nothing is selected by the OS, USB is the
default.

dt-bindings: sram: qcom,imem: Narrow allowed reboot modes

2026-07-01T19:57:43+00:00

Only few Qualcomm IMEM devices actually provide interface for setting
reboot modes, but top-level schema allows "reboot-mode" child for
everyone.  Narrow this to specific compatibles.

syscon-reboot-mode schema allows arbitrary "mode-.* properties but only
a subset actually makes sense and is valid.  Provide negative look-ahead
pattern to disallow any modes not supported by the device, which
tightens the binding even more.

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add support for handling multiple cells in "iommu-map" entries

   - Support only 1 entry in /reserved-memory "reg" entries. Support for
     more than 1 entry has been broken

   - Fix a UAF on alloc_reserved_mem_array() failure

   - Make "ibm,phandle" handling logic specific to PPC

   - Use memcpy() instead of strcpy() for known length strings

   - Ensure __of_find_n_match_cpu_property() handles malformed "reg"
     entries

   - Add various checks that expected strings are strings before
     accessing them

   - Drop redundant memset() when unflattening DT

  DT bindings:

   - Add a DTS style checker. Currently hooked up to dt_binding_check to
     check examples

   - Convert st,nomadik platform, ti,omap-dmm, and ti,irq-crossbar
     bindings to DT schema

     Embedded Controller, Qualcomm IPQ6018 PWM controller, fsl,mc1323,
     Samsung SOFEF01-M DDIC panel, Freescale i.MX53 Television Encoder,
     Samsung S2M series PMIC extcon, and MT6365 PMIC AuxADC schemas

   - Extend bindings for QCom Maili and Nord PDC, QCom Hali fastrpc,
     qcom,eliza-imem, qcom,oryon-1-5 CPU, and MT6365 Keys

   - Consolidate "sram" property definitions

   - Fix constraints on "nvmem" properties which only contain phandles
     and no arg cells

   - Another pass of fixing "phandle-array" constraints

   - Add Gira vendor prefix"
