Thomas, Since I commented on previous versions of this patch, I would have loved to have been CCed on this new version. ;) On Fri, Apr 5, 2013 at 6:53 AM, Thomas Abraham <thomas.abraham@linaro.org> wrote: > With device core now able to setup the default pin configuration, > the pin configuration code based on the deprecated Samsung specific > gpio bindings is removed. > > Signed-off-by: Thomas Abraham <thomas.abraham@linaro.org> > --- > Changes since v2: > - Changed patch subject from "mmc: dwmmc: let..." to "mmc: dw_mmc: let..." > - Rebased to Chris's latest mmc-next branch. > > drivers/mmc/host/dw_mmc-exynos.c | 38 -------------------------------------- > drivers/mmc/host/dw_mmc.c | 12 ++---------- > drivers/mmc/host/dw_mmc.h | 3 --- > 3 files changed, 2 insertions(+), 51 deletions(-) This patch applies fine but fails to compile on linux-next "next-20130408". You lost the race with: f2f942c mmc: dw_mmc: Check return value of regulator_enable ...that patch adds a "goto err_setup_bus" and you've renamed that label. I guess you get another fun rebase. NOTE: this patch is even more urgent than it was before. It looks like pincontrol stuff has now landed in linux-next which means that Exynos5 devices that need eMMC/SD will no longer boot until this patch goes in. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi Seungwon, Thanks for your Ack. Yes, the pinctrl nodes for Exynos5250 have been merged through kgene's tree.

I have posted the v4 version of this patch taking care of this. Thanks for pointing this out.

With device core now able to setup the default pin configuration, the pin configuration code based on the deprecated Samsung specific gpio bindings is removed.
