Subject: [PATCH 0/6] mips: Add DT bindings for MIPS CDMM and GIC
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. 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.

Changelog prev:
- Add yaml-based bindings file for MIPS CDMM dt-node.
- Convert mti,mips-cpc to DT schema.
- Use a shorter summary describing the bindings modification patches.
- Rearrange the SoBs with adding Alexey' co-development tag.
- Lowercase the hex numbers in the dt-bindings.
