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.
