Subject: [PATCH 00/23] RFC: exynos multiplatform support
Newsgroups: gmane.linux.kernel.samsung-soc
Date: Tuesday 5th March 2013 17:42:10 UTC (over 4 years ago)
Hi everyone,

Although I'm not present at the Linaro Connect hacking
sessions, I am participating remotely and have tried
hacking on multiplatform support for Exynos. This patch
set is far from complete, but I think the patches
can be useful anyway.

The series gets increasingly fishy towards the end,
and we should probably not apply any of the last nine
patches as-is, nor do I expect everything to work, since
I have not tested them at all.

With this patch set, we can build mach-exynos as part
of a multiplatform kernel, with the following caveats:

* Only DT based boards are supported
* Moving to common-clk breaks things including cpufreq
  and others. Thomas is working on a patch for this
* We disable the gpio implementation, which also breaks
  stuff, but Thomas has a patch already
* Using the generic DMA engine API in SPI and ASoC
  means they no longer work on S3C
* I did not like the solution for the UART driver, but
  could also not think of a better one.
* The FB_S3C, S3C2410_WATCHDOG and S3C_ADC drivers
  are left as an exercise to the reader, they are
  currently disabled with multiplatform
* sparsemem support is not available on multiplatform

The patches are based on v3.9-rc1 and I have pushed
the git branch to

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git
testing/exynos-multiplatform

I have not yet added subsystem maintainers to Cc on the
patches, I'd like to coordinate with the other people
involved first, so see if they already have patches
for the same drivers.
