Merge tag 'memory-controller-drv-6.17' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl into soc/drivers

Memory controller drivers for v6.17 1. Several cleanups: Use dev_fwnode() in OMAP GPMX, convert arm,pl172.txt DT bindings to DT schema, use syscon_regmap_lookup_by_phandle_args() wrapper, correct kerneldoc. 2. Mediatek MT8186 SMI: Extend hardware bandwidth limits to fix VENC hardware during stress testing. 3. Broadcom brcmstb_memc: Add additional fallback compatible and simplify device driver matching. The change comes from Broadcom SoC maintainer (Florian Fainelli), thus its ABI impact is acknowledged. * tag 'memory-controller-drv-6.17' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux-mem-ctrl: dt-bindings: memory: renesas,rzg3e-xspi: Document RZ/V2H(P) and RZ/V2N support memory: brcmstb_memc: Simplify compatible matching dt-bindings: memory-controller: Define fallback compatible memory: omap-gpmx: Use dev_fwnode() memory: mtk-smi: Add ostd setting for mt8186 dt-bindings: memory-controllers: convert arm,pl172.txt to yaml format memory: stm32_omm: Use syscon_regmap_lookup_by_phandle_args memory: emif: Add missing kerneldoc for lpmode Link: https://lore.kernel.org/r/20250715095315.59299-2-krzysztof.kozlowski@linaro.org Signed-off-by: Arnd Bergmann

dt-bindings: memory: tegra: Add Tegra264 support

2025-07-11T14:48:06Z

Add bindings for the Memory Controller (MC) and External Memory Controller (EMC) found on the Tegra264 SoC. Tegra264 SoC has a different number of interrupt lines for MC sub-units: UCF_SOC, hub, hub common, syncpoint and MC channel. The total number of interrupt lines is eight. Update maxItems for MC interrupts accordingly. This also adds a header containing the memory client ID definitions that are used by the interconnects property in DT and the tegra_mc_client table in the MC driver. These IDs are defined by the hardware, so the numbering doesn't start at 0 and contains holes. Also added are the stream IDs for various hardware blocks found on Tegra264. These are allocated as blocks of 256 IDs and each block can be subdivided for additional fine-grained isolation if needed.

dt-bindings: memory: renesas,rzg3e-xspi: Document RZ/V2H(P) and RZ/V2N support

2025-07-09T18:23:59Z

Document support for the Expanded Serial Peripheral Interface (xSPI) controller found on the Renesas RZ/V2H(P) (R9A09G057) and RZ/V2N (R9A09G056) SoCs. The xSPI hardware block on these SoCs is functionally identical to the one on the RZ/G3E (R9A09G047) SoC. Therefore, the existing driver can be reused without modification by using `renesas,r9a09g047-xspi` as a fallback compatible.

dt-bindings: memory-controller: Define fallback compatible

2025-06-27T05:47:49Z

All of the DDR controllers beyond revision b.2.1 have had a consistent layout, therefore define a "brcm,brcmstb-memc-ddr-rev-b.2.1" fallback compatible string to match them all rather than having to continuously add to the list.

dt-bindings: memory-controllers: Add STM32 Octo Memory Manager controller

2025-05-07T09:27:00Z

Add bindings for STM32 Octo Memory Manager (OMM) controller. OMM manages: - the muxing between 2 OSPI busses and 2 output ports. There are 4 possible muxing configurations: - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2 output is on port 2 - OSPI1 and OSPI2 are multiplexed over the same output port 1 - swapped mode (no multiplexing), OSPI1 output is on port 2, OSPI2 output is on port 1 - OSPI1 and OSPI2 are multiplexed over the same output port 2 - the split of the memory area shared between the 2 OSPI instances. - chip select selection override. - the time between 2 transactions in multiplexed mode.

dt-bindings: memory-controllers: qcom,ebi2: Enforce child props

2025-03-07T21:18:44Z

Qualcomm EBI2 peripheral properties were moved from the device schema to separate "peripheral-props" schema for child node, but the device schema does not reference the new one. Reference the peripheral-props schema so the child nodes will be properly validated from the device schema.
