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. So here 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 and 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 since I'll be working on our MIPS-based SoC drivers integrating into the mainline kernel repo anyway. It's Baikal-T1 SoC based MIPS Warrior P5600 CPU core (you might have noticed a lot of drivers/patches I've recently submitted for review). If you don't like this idea, please just decline the last patch in the series.
