Given how deeply integrated the MIPS GIC is in the architecture, I'd really like Thomas to co-maintain it, or at the very least give his blessing on you being the dedicated point of contact for MIPS GIC stuff. Thanks, M.

I don't mind either way. First option might be even better. Thomas, what do you think? -Sergey > > Thanks, > > M. > -- > Jazz is not dead. It just smells funny...

As soon as we finish a discussion regarding the files-list ordering raised around the last patch in the series, I'll resend the patchset with you added to the list of the MIPS core drivers maintainers. -Sergey > Thomas. > > -- > Crap can work.

Folks, the code and DT-related patches here have been mostly reviewed. Please consider merge the series in or at least give me a feedback to update the series, since merge window is getting opened tomorrow and I would really appreciate to see the leftover being merged in. Regarding this patchset origin. Recently I've submitted a series of patchset's which provided multiple fixes for the MIPS arch subsystem and the MIPS GIC and DW APB Timer drivers, which were required for the Baikal-T1 SoC correctly working with those drivers. Mostly those patchsets have been already merged into the corresponding subsystems, but several patches have been left floating since noone really responded for review except Rob provided his approval regarding DT bindings. Thus in this patchset I've collected all the leftovers so not to loose them in a pale of the maintainers email logs. The patchset includes the following updates: MIPS CPC and GIC DT bindings legacy text-based file are converted to the DT schema (Rob has already reviewed them), add MIPS CDMM DT node support to place the CDMM block at the platform-specific MMIO range, make sure MIPS CDMM is available for MIPS_R5 CPUs. Seeing the series concerns the MIPS-related drivers it's better to merge it in through the MIPS repository: https://git.kernel.org/pub/scm/linux/kernel/git/mips/linux.git/ This patchset is rebased and tested on the mainline Linux kernel 5.7-rc4: base-commit: 0e698dfa2822 ("Linux 5.7-rc4") tag: v5.7-rc4 Suggestion. Since Paul isn't looking after the MIPS arch code anymore, Ralf hasn't been seen maintaining MIPS for a long time, Thomas is only responsible for the next part of it: F: Documentation/devicetree/bindings/mips/ F: Documentation/mips/ F: arch/mips/ F: drivers/platform/mips/ the MIPS-specific drivers like: F: drivers/bus/mips_cdmm.c F: drivers/irqchip/irq-mips-cpu.c F: drivers/irqchip/irq-mips-gic.c F: drivers/clocksource/mips-gic-timer.c F: drivers/cpuidle/cpuidle-cps.c seem to be left for the subsystems maintainers to support. So if you don't mind or unless there is a better alternative, I can help with looking after them to ease the maintainers review burden and since I'll be working on our MIPS-based SoC drivers integrating into the mainline kernel repo anyway. If you don't like this idea, please just decline the last patch in the series.
