Subject: [PATCH 0/8] arm: renesas: Change platform dependency to ARCH_RENESAS

Hi all,

Commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS")
started the conversion from ARCH_SHMOBILE to ARCH_RENESAS for Renesas
ARM SoCs. This patch series completes the conversion, by:
1. Updating dependencies for drivers that weren't converted yet,
2. Removing the ARCH_SHMOBILE Kconfig symbols on ARM and ARM64.

The first 6 patches can be applied independently by subsystem
maintainers.
The last two patches depend on the first 6 patches, and are thus marked
RFC.

Thanks for your comments!

Since commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS")
is CONFIG_ARCH_RENESAS a more appropriate platform check than the legacy
CONFIG_ARCH_SHMOBILE, hence use the former.

Renesas SuperH SH-Mobile SoCs are still covered by the CONFIG_CPU_SH4
check.

This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near
future.

Subject: [PATCH/RFC 7/8] ARM: shmobile: Remove the ARCH_SHMOBILE Kconfig symbol

All drivers for Renesas ARM SoCs have gained proper ARCH_RENESAS
platform dependencies. Hence finish the conversion from ARCH_SHMOBILE
to ARCH_RENESAS for Renesas 32-bit ARM SoCs, as started by commit
9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS").

This depends on the previous patches in this series, hence the RFC.

JFTR, after this, the following symbols for drivers supporting only
Renesas SuperH "SH-Mobile" SoCs can no longer be selected:
- CONFIG_KEYBOARD_SH_KEYSC,
- CONFIG_VIDEO_SH_VOU,
- CONFIG_VIDEO_SH_MOBILE_CEU,
- CONFIG_DRM_SHMOBILE[*],
- CONFIG_FB_SH_MOBILE_MERAM.
(changes for a shmobile_defconfig .config)

[*] CONFIG_DRM_SHMOBILE has a dependency on ARM, but it was never wired
up. From the use of sh_mobile_meram, I guess it was meant for
SH-Mobile AP4 on Mackerel or AP4EVB, which are long gone.
So the only remaining upstream platforms that could make use of it
are legacy SuperH SH-Mobile SoCs?

Subject: [PATCH/RFC 8/8] arm64: renesas: Remove the ARCH_SHMOBILE Kconfig symbol

The Kconfig symbol for Renesas 64-bit ARM SoCs has always been
ARCH_RENESAS, with ARCH_SHMOBILE being selected to reuse drivers shared
with Renesas 32-bit ARM and/or Renesas SuperH SH-Mobile SoCs.

Commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS")
started the conversion from ARCH_SHMOBILE to ARCH_RENESAS for Renesas
32-bit SoCs. Now all drivers for Renesas ARM SoCs have gained proper
ARCH_RENESAS platform dependencies, there is no longer a need to select
ARCH_SHMOBILE.

With ARCH_SHMOBILE gone, move the ARCH_RENESAS section up, to restore
alphabetical sort order.

Subject: [PATCH 2/8] dmaengine: shdmac: Change platform check to CONFIG_ARCH_RENESAS

Since commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS")
is CONFIG_ARCH_RENESAS a more appropriate platform check than the legacy
CONFIG_ARCH_SHMOBILE, hence use the former.

Renesas SuperH SH-Mobile SoCs are still covered by the CONFIG_CPU_SH4
check, just like before support for Renesas ARM SoCs was added.

Instead of blindly changing all the #ifdefs, switch the main code block
in sh_dmae_probe() to IS_ENABLED(), as this allows to remove all the
remaining #ifdefs.

This will allow to drop ARCH_SHMOBILE on ARM in the near future.

Would it not make sense to try to apply everything en masse rather than
delaying? I'm happy to apply the subsystem stuff but if it gets things
done quicker or more efficiently I'm also happy to have the lot merged
as one series.

Unless you would like to merge the whole series in one go, I'll take this in
my tree as I have a conflicting patch I would like to submit for v4.18.

In theory, yes.

However, this touches multiple subsystems, and it's non-critical, so I don't
want to spent the energy to get this done in a synchronized way.
It's way easier to postpone the last (RFC) patches when everything else
has been applied by subsystem maintainers.

So please apply your part, thanks!

That sounds about right. If there is interest I can sift through my mail
archive and see if it yields any answers.

Thanks, I have marked this and the following patch as deferred.
Please repost or otherwise ping me once the dependencies are in place.

Apparently CONFIG_VIDEO_SH_MOBILE_CEU was set in the old
armadillo800eva_defconfig, and used by the old board code.

While DT bindings do exist [1], some DT support has been added to the
driver [2], and this even ended up as the example in [3], this was never
enabled in the corresponding board DTS.

Nevertheless, I understand that soc_camera-based driver is obsolete, and
has been replaced by [4], but bindings for r8a7740 are lacking [5].
