Subject: [PATCH v5 0/6] mips: Add DT bindings for MIPS CDMM and MIPS GIC
Daniel, Rafael, Thomas (Gleixner), could you specifically take a look at
the last patch in this series? If you are ok with that, please explicitly
ack. We need at least one of your blessing to merge the series in, since
the code and DT-related patches here have been mostly reviewed. We've
missed the last merge window. It would be pity to miss the next one...
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. Thomas agreed to join in maintaining that drivers.
