Remove what is upstream for now, until the out-of-tree implementation is in suitable form for merging. An important side effect of this patch is that it allows the building of a Zynq kernel without running into unresolved symbol problems: drivers/built-in.o: In function `amba_get_enable_pclk': clkdev.c:(.text+0x444): undefined reference to `clk_enable' drivers/built-in.o: In function `amba_remove': clkdev.c:(.text+0x488): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_probe': clkdev.c:(.text+0x540): undefined reference to `clk_disable' drivers/built-in.o: In function `amba_device_add': clkdev.c:(.text+0x77c): undefined reference to `clk_disable' drivers/built-in.o: In function `enable_clock': clkdev.c:(.text+0x29738): undefined reference to `clk_enable' drivers/built-in.o: In function `disable_clock': clkdev.c:(.text+0x29778): undefined reference to `clk_disable' drivers/built-in.o: In function `__pm_clk_remove': clkdev.c:(.text+0x297f8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_suspend': clkdev.c:(.text+0x29bc8): undefined reference to `clk_disable' drivers/built-in.o: In function `pm_clk_resume': clkdev.c:(.text+0x29c28): undefined reference to `clk_enable' make[2]: *** [vmlinux] Error 1 make[1]: *** [sub-make] Error 2 make: *** [all] Error 2 In addition, eliminate Zynq's "use" of the versatile platform, as it is no longer needed. As Nick Bowler points out: For the record, I think this was introduced by commit 56a34b03ff427 ("ARM: versatile: Make plat-versatile clock optional") which forgot to select PLAT_VERSATILE_CLOCK on Zynq. This is not all that surprising, because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in the Makefile. Nevertheless, the only feature from versatile that Zynq needed was the clock support, so this patch should *also* delete the secret use of plat-versatile by removing this line from arch/arm/Makefile: plat-$(CONFIG_ARCH_ZYNQ) += versatile Signed-off-by: Josh Cartwright Cc: John Linn Acked-by: Arnd Bergmann Tested-by: Michal Simek --- arch/arm/Kconfig | 1 - arch/arm/Makefile | 1 - arch/arm/mach-zynq/common.c | 1 - arch/arm/mach-zynq/include/mach/clkdev.h | 32 -------------------------------- 4 files changed, 35 deletions(-) delete mode 100644 arch/arm/mach-zynq/include/mach/clkdev.h diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index ef6d059..3ab72e1 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -948,7 +948,6 @@ config ARCH_ZYNQ bool "Xilinx Zynq ARM Cortex A9 Platform" select ARM_AMBA select ARM_GIC - select CLKDEV_LOOKUP select CPU_V7 select GENERIC_CLOCKEVENTS select ICST diff --git a/arch/arm/Makefile b/arch/arm/Makefile index 451757d..8dbab2d 100644 --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -197,7 +197,6 @@ machine-$(CONFIG_ARCH_ZYNQ) += zynq # by CONFIG_* macro name. plat-$(CONFIG_ARCH_OMAP) += omap plat-$(CONFIG_ARCH_S3C64XX) += samsung -plat-$(CONFIG_ARCH_ZYNQ) += versatile plat-$(CONFIG_PLAT_IOP) += iop plat-$(CONFIG_PLAT_NOMADIK) += nomadik plat-$(CONFIG_PLAT_ORION) += orion diff --git a/arch/arm/mach-zynq/common.c b/arch/arm/mach-zynq/common.c index 056091a..ba48f06 100644 --- a/arch/arm/mach-zynq/common.c +++ b/arch/arm/mach-zynq/common.c @@ -31,7 +31,6 @@ #include #include -#include #include "common.h" static struct of_device_id zynq_of_bus_ids[] __initdata = { diff --git a/arch/arm/mach-zynq/include/mach/clkdev.h b/arch/arm/mach-zynq/include/mach/clkdev.h deleted file mode 100644 index c6e73d8..0000000 --- a/arch/arm/mach-zynq/include/mach/clkdev.h +++ /dev/null @@ -1,32 +0,0 @@ -/* - * arch/arm/mach-zynq/include/mach/clkdev.h - * - * Copyright (C) 2011 Xilinx, Inc. - * - * This software is licensed under the terms of the GNU General Public - * License version 2, as published by the Free Software Foundation, and - * may be copied, distributed, and modified under those terms. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
