2013-06-17ARM: imx: create mxc_arch_reset_init_dt() for DT bootShawn Guo
The mxc_arch_reset_init() uses static mapping and calls clk_get_sys() to get clock. It's suitable for non-DT boot but not for DT boot where dynamic mapping and of_clk_get() should be used instead. Create mxc_arch_reset_init_dt() as the DT variant of mxc_arch_reset_init(), and change DT platforms to use it. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-06-17ARM: imx: move clk_prepare() out from mxc_restart()Shawn Guo
It's inappropriate to call clk_prepare() in mxc_restart(), because the restart routine could be called in atomic context. Move clk_get() and clk_prepare() into mxc_arch_reset_init() and only have the atomic part clk_enable() be called in mxc_restart(). As a result, mxc_arch_reset_init() needs to be called after clk gets initialized. While there, it also changes printk(KERN_ERR ...) to pr_err() and adds __init annotation for mxc_arch_reset_init().

2013-02-01ARM: imx: fix imx31-dt.c time-related warningStephen Warren
Commit 6bb27d7 "ARM: delete struct sys_timer" caused the following: arch/arm/mach-imx/imx31-dt.c:56:2: warning: initialization from incompatible pointer type [enabled by default] arch/arm/mach-imx/imx31-dt.c:56:2: warning: (near initialization for ‘__mach_desc_IMX31_DT.init_time’) [enabled by default] This is because mx31_clocks_init_dt() returns int, whereas the .init_time field prototype expects a function returning void. Implement a wrapper so that the prototypes match.

2012-12-24ARM: delete struct sys_timerStephen Warren
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.

2012-10-15ARM: imx: include hardware.h rather than mach/hardware.hShawn Guo
It moves a bunch of header files included in hardware.h and itself from mach-imx/include/mach to mach-imx, and updates users to include hardware.h rather than mach/hardware.h. The files in mach-imx/devices will need to include "../hardware.h".

2012-10-15ARM: imx: include common.h rather than mach/common.hShawn Guo
Rename mach-imx/include/mach/common.h to mach-imx/common.h and update all users to include common.h rather than mach/common.h. It also removes an unneeded inclusion to common.h in mach-imx/devices/devices.c.
