Commit 802a5639aa7041b2 ("ARM: shmobile: r8a7740: add A3SP pm domain
support") added the A3SP power domain, but forgot to hook up the IPPMU,
DMAC0/1/2, and USBDMAC hardware blocks.

Commit 802a5639aa7041b2 ("ARM: shmobile: r8a7740: add A3SP pm domain
support") added the A3SP power domain, but forgot to hook up the TPU,
SDHI0/1, and MMCIF hardware blocks.
Note: As the default PM QoS latency constraint for SDHI is only 100 ?s
(cfr. commit c419e611c3c59c0e ("tmio_mmc / PM: Use PM QoS latency
constraint"), while DEFAULT_DEV_LATENCY_NS is 250000, suspend fails with
-EBUSY, unless the constraint is increased first to more than 500 ?s
using e.g.
echo 501 > /sys/devices/platform/sh_mobile_sdhi.0/power/pm_qos_resume_latency_us

Add support for the A3RV power domain.
This domain contains the VPU5F and VCP1 hardware blocks, which are
currently not used by any driver.

Add support for the A3SG power domain, and hook it up as a subdomain of
A4S.
This domain contains the SGX540 hardware block, which is currently not
used by any driver.

Add support for the A4MP power domain, and hook up the HDMI-Link and FSI
hardware blocks.
This domain also contains the SPU2, FMSI, and BBIF2 hardware blocks,
but these are currently not used by any driver.

v2:
- Also hook up HDMI-Link, which was not documented in the datasheet as
belonging to A4MP,
- Really add A4MP and drop the FIXME, as a fix for the interrupt storm

Is it possible to split this into two patches.
A board patch (that touches board-armadillo800eva.c)
and an SoC patch (the rest). Likewise for any remaining
patches in this series that touch both board and SoC code.
The reason for this is that it would make the patches fit
the branch scheme that arm-soc people like. In particular splitting
patches between soc and boards branches.
Please note that I have queued up four of the SoC earlier patches in the
series. You don't need to repost them.

I kept them together as adding the PM domain without the devices will
cause regressions (the PM domain core will power down the PM domain as
it doesn't know about the to-be-added devices, and thus thinks it's unused).
As the link from a device to a PM domain is a name string, and not a
C reference, I could split them in two parts: first the board part
that adds some
devices, and then the SoC part that adds the PM domain and more devices.
But only if you can guarantee that the SoC part will be merged first, also
by arm-soc and Linus.
Still, I prefer to keep them together. Hooking up devices to PM domains is
SoC-specific, not board specific (for DT it lives in the .dtsi). It's
unfortunate this code is in the board-specific C files due to board-specific
configuration (cfr. .dts overriding/extending .dtsi).
What do you think? Do you agree?
Thanks!
Gr{oetje,eeting}s,
Geert

Hi Geert, thanks for the explanation. I agree that it makes sense
to keep things together. I'll see about queuing-up your series as-is.

Add support for the D4 power domain.
This domain contains the Coresight-ETM hardware block.
As long as the ARM debug/perf code doesn't use resource management with
runtime PM support, the D4 power domain must be kept powered to avoid a
crash during resume from s2ram (dbg_cpu_pm_notify() calls
reset_ctrl_regs() unconditionally, causing an undefined instruction
oops).
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v3:
- Always keep D4 powered, until the new Coresight code handles runtime
PM,
v2:
- Really add D4 and drop the FIXME, as a fix for the crash is
available.

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.

Add support for the A4SU power domain.
This domain contains the USBPHY hardware block, which is currently not
used by any driver.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v3:
- No changes,
v2:
- Drop FIXME about hooking up USB platform devices, as the Armadillo
platform code doesn't register a USB host device anyway?

Add support for the A3SM power domain, and hook it up as a subdomain of
A4S.
This domain contains the System CPU (Cortex-A9) hardware block. Hence
move the special CPU handling from A4S to A3SM.

v3:
- No changes,
v2:
- Move special CPU domain handling from A4S to A3SM,
- Drop FIXME about not powering down A4S, as this is expected behavior.
