Renesas ARM platforms are transitioning from single-platform to
multi-platform kernels using the new ARCH_SHMOBILE_MULTI. Make the
driver available on all ARM platforms to enable it on both ARCH_SHMOBILE
and ARCH_SHMOBILE_MULTI, and increase build testing coverage with

[PATCH v2 08/19] mmc: sdhi: Enable the driver on all ARM platforms

[Laurent Pinchart]

Renesas ARM platforms are transitioning from single-platform to
multi-platform kernels using the new ARCH_SHMOBILE_MULTI. Make the
driver available on all ARM platforms to enable it on both ARCH_SHMOBILE
and ARCH_SHMOBILE_MULTI, and increase build testing coverage with
COMPILE_TEST.

Whether the CTL_DMA_ENABLE register is part of the standard TMIO
controller or is Renesas-specific is unknown and impossible to test as
we have no current or planned TMIO DMA users other than SUPERH and
ARCH_SHMOBILE. Writing to the register is thus conditionally compiled
for SUPERH and ARCH_SHMOBILE only. Adding ARCH_SHMOBILE_MULTI to the
list would extend this to multiarch kernels, but would break the driver
for non-shmobile platforms if the register is Renesas-specific. We can
thus get rid of the conditional compilation completely without
introducing any further issue, and let future non-Renesas users deal
with the situation if it turns out to be a the problem.

[PATCH] mmc: sdhi: Enable the driver on all ARM platforms

[Laurent Pinchart]

Renesas ARM platforms are transitioning from single-platform to
multi-platform kernels using the new ARCH_SHMOBILE_MULTI. Make the
driver available on all ARM platforms to enable it on both ARCH_SHMOBILE
and ARCH_SHMOBILE_MULTI and increase build testing coverage.

Don't enable COMPILE_TEST support as the driver doesn't compile on x86
due (possibly among others) to missing readsw/writesw I/O accessors.

Whether the CTL_DMA_ENABLE register is part of the standard TMIO
controller or is Renesas-specific is unknown and impossible to test as
we have no current or planned TMIO DMA users other than SUPERH and
ARCH_SHMOBILE. Writing to the register is thus conditionally compiled
for SUPERH and ARCH_SHMOBILE only. Adding ARCH_SHMOBILE_MULTI to the
list would extend this to multiarch kernels, but would break the driver
for non-shmobile platforms if the register is Renesas-specific. We can
thus get rid of the conditional compilation completely without
introducing any further issue, and let future non-Renesas users deal
with the situation if it turns out to be a the problem.

Hi Laurent,

Thanks for your efforts. Hate to slow things down, but this last hunk
looks wrong to me. I believe the reason for the #ifdef is that
non-Renesas IP may be using the tmio_mmc driver, at least they used
to. Not sure if anyone is using DMA Engine though. If I were you I
would play it safe and simply update the #ifdef with same kind of
dependencies that the Kconfig bits have.

Also, it would of course be nice to clean up the driver, perhaps with
a feature flag for this special register or why not simply move the
code to the sdhi file. But that's not really related to your
multiplatform kconfig change, is it? =)

There are several points to consider here.

- drivers/mmc/host/tmio_mmc_dma.c is only compiled in when CONFIG_MMC_SDHI is 
selected. The symbol currently depends on SUPERH || ARCH_SHMOBILE. We thus 
have no non-Renesas users for TMIO DMA at the moment.

- I don't know whether the CTL_DMA_ENABLE register is specific to Renesas or 
not. I haven't been able to find a publicly available copy of the TMIO 
documentation. The Renesas datasheets I have access to don't document the SDHI 
module. Can you comment on that ?

- Merely adding CONFIG_ARCH_SHMOBILE_MULTI to the CTL_DMA_ENABLE write #if 
guard will break on multiplatform kernels anyway. If a non-Renesas platform 
uses TMIO DMA, a kernel that supports both a Renesas SoC and that non-Renesas 
platform will have the CTL_DMA_ENABLE code compiled in.

For those reasons I have decided to remove the #if and defer the fix (if 
needed, if CTL_DMA_ENGINE is indeed Renesas-specific) to the first non-Renesas 
TMIO DMA user.

No, it isn't :-) I could try to find time to fix that later, but I don't like 
adding support for features that are not used. I would first want to be sure 
that the CTL_DMA_ENABLE register is indeed Renesas-specific, which might be a 
bit hard to ascertain of no non-Renesas chip implements TMIO DMA :-)

While the below compiler warnings have been seen with sh-randconfig
before, they're more likely to happen with COMPILE_TEST=y.
I now see them with e.g. m68k-allmodconfig, so I created a patch.

I'm a bit surprised, looking at the definition of UNIVERSAL_DEV_PM_OPS, I 
would have thought that both functions would be used when either 
CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME is defined. I would thus have guarded 
both functions with #if defined(CONFIG_PM_SLEEP) || 
defined(CONFIG_PM_RUNTIME).

You're right. I missed that both function pointers are passed to both macros.

Will send v2.

Thank you, but if it's not too late, can you drop the patch ? :-) We've 
settled for a different approach that renames Kconfig symbols and doesn't 
require changes to individual drivers.

No problem. It's dropped.

I was only paying attention to the cover letter, where that decision
apparently didn't show up :)

This patch is in mainline as d4f9e7b3d12e92ede642f6f4fc7d959f06da8ccc
since v3.13-rc1. I wonder if

	depends on HAVE_CLK && (SUPERH || ARCH_SHMOBILE || COMPILE_TEST)

isn't the better option. (Since bf98c1eac1d4a6bcf00532e4fa41d8126cd6c187
ARCH_SHMOBILE is enabled for both multi-platform and legacy shmobile
configs.) Or do you plan to deprecate ARCH_SHMOBILE?

Best regards
Uwe
