The MediaTek scene saw a generous increase in number of patches that are sent to the lists every week, increasing the amount of required efforts to maintain the MTK bits overall, and we will possibly see even more of that. For this reason, and also because of suggestions and encouragement coming from the community, I'm stepping up to be a co-maintainer of MediaTek SoCs support.

a=openpgp; fpr=57152E620CAF29C5DBE574766833ABB5BEBAF7B7 From: "Nícolas F. R. A. Prado" The DSU PMU allows monitoring performance events in the DSU cluster, which is done by configuring and reading back values from the DSU PMU system registers. However, for write-access to be allowed by ELs lower than EL3, the EL3 firmware needs to update the setting on the ACTLR3_EL3 register, as it is disallowed by default. That configuration is not done on the firmware used by the MT8195 SoC, as a consequence, booting a MT8195-based machine like mt8195-cherry-tomato-r2 with CONFIG_ARM_DSU_PMU enabled hangs the kernel just as it writes to the CLUSTERPMOVSCLR_EL1 register, since the instruction faults to EL3, and BL31 apparently just re-runs the instruction over and over. Mark the DSU PMU node in the Devicetree with status "fail", as the machine doesn't have a suitable firmware to make use of it from the kernel, and allowing its driver to probe would hang the kernel.
