This series has been tested on the following SoCs: - SM7475 - SM8450 - SM8475 In these the modem works as expected and no crashes occur. Signed-off-by: Esteban Urrutia <redacted> --- Changes in v2: - Add missing resource limits for DMA and QDSS source groups. - These are marked as unused downstream, but still have values written to them. - Add Nazar as a co-developer. - We developed independent implementations and are both working on this series. - Add the IPA_MEM_MODEM_STATS_DROP memory region. - Pick tags. - Rebase against linux-next. - Remove comment in driver stating smem_size differences. For both SM8450 and SM8475 SoCs: - All devices based on these SoCs use an smem_size of 0x9000. [1] - Specifying an smem_size of 0xb000 causes the modem to assert a shared memory allocation failure. [2] - Remove overlapping optional memory regions. - No comments from anyone regarding these, so remove them. - Reorder patches. (Dmitry, Krzysztof) - Sort iommus property in DT. (Krzysztof) - Specify actual IMEM base and size in DT. (Konrad) - Update commit messages and cover letter. - Link to v1: https://patch.msgid.link/20260622-sm8450-ipa-v1-0-532f0299f96e@proton.me [1] https://github.com/sm8450-mainline/fdt [2] https://github.com/dopaemon/android_kernel_xiaomi_sm8450-devicetrees/commit/0cff0b070363fb9a312ba6e66244898013e7038f To: Andrew Lunn <andrew+netdev@lunn.ch> To: "David S.
