[GIT PULL] memory: drivers for v7.4

[Krzysztof Kozlowski]

Hi Arnd and SoC folks,

Note that I do not treat untested, LLM-assisted fixes as critical fixes, thus
usually do not take them into fixes cycle.

Best regards,
Krzysztof

  memory: stm32_omm: fix child clock leak on set_amcr() error path (2026-09-23 19:57:14 +0200)

----------------------------------------------------------------
Memory controller drivers for v7.4

1. Broadcom DPFE: Fix handling kernel memory accesses with malicious or
   compromised firmware and possible out-of-bounds read triggered by
   buggy co-processor.  Also validate firmware image contents before
   processing it.

2. Renesas RPC IF: One fix for volatile register access, several
   cleanups and enable autosuspend in runtime PM.

3. Several minor improvements and fixes for various drivers: TI EMIF,
   Samsung Exynos5422 DMC, Nvidia Tegra264 and STM32 OMM.  The fixes
   seems to be effect of LLM usage, thus they were neither reproduced
   nor tested, making them non-critical fixes.

4. Mediatek SMI: Add support for MT8189 SoC.
