2013-09-29ARM: vt8500: prepare for arch-wide .init_time callbackSebastian Hesselbarth
Current vt8500 board init calls of_clk_init() from vtwm_clk_init. To allow consolidation of DT driven .time_init, move of_clock_init() to a temporary .time_init callback that will be removed when arch-wide callback is available. With previous pmc_base parsing helper for vt8500 clock providers, we can also safely remove the call to vtwm_clk_init() and get rid of some includes.

2013-05-20ARM: vt8500: Add missing NULL terminator in dt_compatSrinivas Kandagatla
When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it failed to boot. The issues seems to be changing by enabling or disabling VT8550 platform. Having a quick look at dt_compat list, it seems to miss a NULL terminator, which means of_flat_dt_match will compat check will cross the boundary of dt_compat and fault at some point , which is what was happening in my case. Without this patch if we try to boot multi_v7_defconfig you might notice that some of the platforms might fault if they fall after vt8500 in machine-desc list. Other platforms which fall before vt8500 in mdesc list will not fault.

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.
