Hi Linus, Kukjin, Patch titled "pinctrl: exynos: change PINCTRL_EXYNOS option" (linux-next commit Id: 7452b64d) which is present in linux-next is missing in the mainline kernel. This patch is required along with the patch "gpio: samsung: fix pinctrl condition for exynos and exynos5440" (mainline commit Id: e4a5da51) which has already made it into mainline. Without the missing patch we get the following boot up warnings and subsequent failures with dt boot on 4412 based board: WARNING: at drivers/gpio/gpio-samsung.c:3102 samsung_gpiolib_init+0x29c/0x2e8() Unknown SoC in gpio-samsung, no GPIOs added Modules linked in: [<c00142dc>] (unwind_backtrace+0x0/0xf8) from [<c00202bc>] (warn_slowpath_common+0x4c/0x64) [<c00202bc>] (warn_slowpath_common+0x4c/0x64) from [<c0020368>] (warn_slowpath_fmt+0x30/0x40) [<c0020368>] (warn_slowpath_fmt+0x30/0x40) from [<c028b924>] (samsung_gpiolib_init+0x29c/0x2e8) [<c028b924>] (samsung_gpiolib_init+0x29c/0x2e8) from [<c000862c>] (do_one_initcall+0x34/0x174) [<c000862c>] (do_one_initcall+0x34/0x174) from [<c0275960>] (kernel_init_freeable+0xfc/0x1c8) [<c0275960>] (kernel_init_freeable+0xfc/0x1c8) from [<c01c0a5c>] (kernel_init+0x8/0xe4) [<c01c0a5c>] (kernel_init+0x8/0xe4) from [<c000e158>] (ret_from_fork+0x14/0x3c) -- With warm regards, Sachin -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
