[PATCH 00/11] ARM: shmobile: r8a7740/armadillo legacy prototype pm domain support

[Geert Uytterhoeven]

	Hi Simon, Magnus,

This series contains prototype patches to improve pm domain support for
r8a7740/armadillo800eva, mimicking (parts of) the existing pm domain support
for sh7372/mackerel.

More specifically, they
  - Add missing devices to existing pm domains,
  - Add missing pm domains, hooking up devices and subdomains,

There are a few things commented out, and a few rough edges or missing things
(cfr. the patches marked with "[WIP]", and the "FIXME" sections therein),
but the result does boot, and s2ram works.

Please note that DT/multi-platform support will be added later.

This series depends on my series "[PATCH 0/5] ARM: shmobile: pm domain
improvements and cleanups".

Thanks for your comments and suggestions!

[PATCH 08/11] [WIP] ARM: shmobile: r8a7740: Add D4 pm domain support

[Geert Uytterhoeven]

Add support for the D4 power domain.
This domain contains the Coresight-ETM hardware block.

FIXME: D4 is not added, as this breaks resume (dbg_cpu_pm_notify() calls
       reset_ctrl_regs(), which crashes as D4 is powered down, and commit
       0d352e3d006c9589 ("ARM: hw_breakpoint: trap undef instruction
       exceptions in reset_ctrl_regs") doesn't seem to work...)

[PATCH 09/11] ARM: shmobile: r8a7740/armadillo legacy: Add A4R pm domain support

[Geert Uytterhoeven]

Add support for the A4R power domain, and hook up the A3RV subdomain,
and the CEU0, TMU0, and IIC0 hardware blocks.
This domain also contains the Realtime CPU (SH-4A), Realtime CPU debug
modules, H-UDI, RT-SHwy, INTCS, RT-HPB, VIO6C, JPU, RTDMAC1/2, SSP,
MSIOF0, CMT0, ICB, DREQPAK (RT), 2DDMAC, IPMMUI, and 2DG hardware
blocks, but these are currently not used by any driver.

Re: [PATCH 00/11] ARM: shmobile: r8a7740/armadillo legacy prototype pm domain support

[Simon Horman]

Hi Geert,

I would like Magnus's opinion but mine is that the non-WIP patches
could be queued up. At least patch 1 and 2. Possibly others if
they don't depend (other than diff noise) on WIP patches.

With the WIP patches, I am not entirely opposed to merging them
too, so long as they move things in a good direction. And in particular
don't break anything.

The legacy platforms are meant to be extinct in the near future, but
Armadillo-legacy already has some PM domain support, so adding a
little bit more can't hurt much, IMHO.

Besides diff noise, there should not be any dependencies on WIP patches.

"[PATCH 03/11] [WIP] ARM: shmobile: armadillo800eva legacy: Add
missing A3SP pm domain devices" should be OK, as this turned out to be
intended behavior.

"[PATCH 10/11] [WIP] ARM: shmobile: r8a7740: Add A4SU pm domain
 support" probably introduces a regression for USB, as the domain is now
powered down after boot-up. I haven't tried USB on Armadillo yet, though.
So don't apply this one.

"[PATCH 11/11] [WIP] ARM: shmobile: r8a7740: Add A3SM pm domain
 support" should be safe.

I would not apply the other WIP patches that add C99-commented-out code.
These issues must be fixed for DT as well.

Thanks!
