[PATCH v2 00/19] Enable various Renesas drivers on all ARM platforms

[PATCH v2 00/19] Enable various Renesas drivers on all ARM platforms

[Laurent Pinchart]

Hello,

This patch series, based on v3.12-rc7, prepares various Renesas drivers
for migration to multiplatform kernels by enabling their compilation or
otherwise fixing them on all ARM platforms. The patches are pretty
straightforward and are described in their commit message.

Changes since v1:

- The drivers can also be selected when COMPILE_TEST is enabled, regardless of
  the architecture. This should provide a good compromise between wide build
  test coverage and not clobbering configuration with drivers useless on
  non-SuperH, non-ARM platforms.

- DMA configuration is now unconditional in patch 08/19

I'd like to get all these patches merged in v3.14. As they will need to go
through their respective subsystems' trees, I would appreciate if all
maintainers involved could notify me when they merge patches from this series
in their tree to help me tracking the merge status. I don't plan to send pull
requests individually for these patches, and I will repost patches
individually if changes are requested during review.

If you believe the issue should be solved in a different way please reply to
the cover letter to let other maintainers chime in.

[PATCH v2 10/19] mtd: sh_flctl: 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.

Applied to l2-mtd.git, branch 'next' (for 3.14). Thanks.

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 :)

I'll reply to the cover letter. Sorry about that.
