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

2025-07-22T20:47:00Z

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

memory: tegra: Add Tegra264 MC and EMC support

2025-07-11T14:49:42Z

Add support to enable Memory Controller (MC) and External Memory Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are mostly the same as Tegra234 but differ in number of channels and interrupt numbers. The patch also adds the bandwidth manager definitions required for Tegra264 and uses them to populate the memory client table. All of these are needed to properly enable memory interconnect (ICC) support.

memory: brcmstb_memc: Simplify compatible matching

2025-06-27T05:47:49Z

Now that a "brcm,brcmstb-memc-ddr-rev-b.2.x" fallback compatible string has been defined, we can greatly simplify the matching within the driver to only look for that compatible string and nothing else. The fallback "brcm,brcmstb-memc-ddr" is also updated to assume the V21 register layout since that is the most common nowadays.

memory: omap-gpmx: Use dev_fwnode()

2025-06-12T11:38:34Z

irq_domain_create_simple() takes fwnode as the first argument. It can be extracted from the struct device using dev_fwnode() helper instead of using of_node with of_fwnode_handle().

memory: mtk-smi: Add ostd setting for mt8186

2025-06-10T08:17:17Z

Add initial ostd setting for mt8186. All the settings come from DE. These settings help adjust Multimedia HW's bandwidth limits to achieve a balanced bandwidth requirement. Without this, the VENC HW works abnormal while stress testing.

memory: stm32_omm: Use syscon_regmap_lookup_by_phandle_args

2025-06-10T08:13:27Z

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over syscon_regmap_lookup_by_phandle() combined with getting the syscon argument. Except simpler code this annotates within one line that given phandle has arguments, so grepping for code would be easier.
