[PATCH 0/3] mmc: renesas_sdhi: Handle resets

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Hi,

Series adds suspend/resume hooks for the Renesas SDHI driver. These
are necessary on RZ/G3{E, S}, that supports a power saving mode where
power to most of the SoC components (including SDHI) is turned off.
Resume from this suspend mode is done with the help of bootloader
and it may choose to disable the SDHI clocks, resets after it is
done with the SDHIs.

Reset signal was deasserted/asserted on probe/remove as well to
avoid relying on previous bootloaders. This is also useful for
unbind/bind operations.

Along with it, driver was converted to use
SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() helpers.

Thank you,
Claudiu

[PATCH 1/3] mmc: renesas_sdhi: Deassert the reset signal on probe

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Deassert the reset signal of the SDHI controller during probe to avoid
relying on the previous bootloaders. Without deasserting the reset signal,
the SDHI controller will not function.

[PATCH 2/3] mmc: renesas_sdhi: Switch to SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() and pm_ptr()

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS() are deprecated now
and require __maybe_unused protection against unused function warnings.
The usage of pm_ptr() and SYSTEM_SLEEP_PM_OPS()/RUNTIME_PM_OPS() allows
the compiler to see the functions, thus suppressing the warning. Thus
drop the __maybe_unused markings.

[PATCH 3/3] mmc: renesas_sdhi: Add suspend/resume hooks

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>

Add suspend/resume hooks which assert/deassert the reset signals, along
with forcing runtime suspend/resume. This allows using the driver in
scenarios where the resume is done with the help of bootloader and the
bootloader disables the SDHI clocks, resets, IRQs before passing execution
to Linux.

Note that this has the side effect of asserting reset again on probe
failure or unbind.  Also on SoCs that boot with reset already deasserted
(e.g. R-Car).  I don't know if that would be a problem.

I agree. I've tested unbind/bind on RZ/G3S and I saw no issue.

>  Also on SoCs that boot with reset already deasserted
> (e.g. R-Car).  I don't know if that would be a problem.

I think all SoCs boot with resets de-asserted as the driver does register
configuration before calling reset_control_reset() in renesas_sdhi_reset(),
e.g:
- one register configuration is just above reset_control_reset()
- one register configuration, through sd_ctrl_write32_as_16_and_16(), in
  renesas_sdhi_probe()
- register writes in tmio_mmc_reset() before host->reset() call

I did bonnie++ tests after boot on RZ/G2{H, M, N, L, UL}, RZ/V2L and saw no
issue.

Thank you for your review,
Claudiu

This change is indeed needed, because RUNTIME_PM_OPS() now

... however, no actual code referencing them is emitted in the
CONFIG_PM=n case, as renesas_sdhi_internal_dmac_dev_pm_ops is not used
due to the use of pm_ptr().  Hence the changes to this file are needed.
(verified with m68k allmodconfig/allyesconfig builds)

Since you confirmed all this, did you forget a Rev-by? Or do you
actually describe an issue which I am overlooking?

You're right, I got confused myself by some comments on pm.h. I'll update
it in the next version.

On RZ/G3S the following were checked:
- run bonnie++ on all the SDHIs (with SD card and eMMC, where possible)
- unbind/bind on all the SDHIs and run bonnie++ (with SD card and eMMC,
  where possible) after re-bind
- 32 consecutive suspend/resume (s2idle and deep) and run bonnie++ (with SD
  card and eMMC where possible) after resume

bonnie++ tests were executed after boot on RZ/G2{H, M, N, L, UL}, RZ/V2L.

Well, #ifdefs, not __maybe_unused.

I removed the chunk mentioned by Geert. I didn't dive into the details,
just tested it.

Thanks, I did some lighter testing on R-Car D3 with bind/unbind and
