2012-12-24ARM: delete struct sys_timerStephen Warren1-8/+1
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-10-29zynq: remove use of CLKDEV_LOOKUPJosh Cartwright2-33/+0
The Zynq support in mainline does not (yet) make use of any of the generic clk or clk lookup functionality. 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 <josh.cartwright@ni.com> Cc: John Linn <john.linn@xilinx.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Tested-by: Michal Simek <michal.simek@xilinx.com>
