reboot: arm: change reboot_mode to use enum reboot_mode

2013-07-09T17:33:29+00:00

Preparing to move the parsing of reboot= to generic kernel code forces the change in reboot_mode handling to use the enum.

ARM: delete struct sys_timer

2012-12-24T16:36:38+00:00

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.

This is a series from Rob Herring that restructures how all pci devices allocate I/O space, and it's part of the work to allow multiplatform kernels. - A number of cleanup series for OMAP, moving and removing some headers, sparse irq rework and in general preparation for multiplatform. - Final removal of all non-DT boards for Tegra, it is now device-tree-only! - Removal of a stale platform, nxp4008. It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel. We have not been able to find anyone interested in keeping it around in the kernel. - Removal of the legacy dmaengine driver on tegra + A handful of other things that I haven't described above."

clk: convert ARM RealView to common clk

2012-08-25T00:42:10+00:00

This converts the ARM RealView machine over to using the common clock. The approach is similar to the one used for the Integrator, and we're reusing the ICST wrapper code. We have to put the clock intialization in the timer init function for the clocks to be available when initializing the timer, keeping them in early_init() is too early for the common clk. Since we now have to go down and compile drivers/clk/versatile a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper code gets compiled into the kernel for either machine. A leftover CLK_VERSATILE in the Integrator Kconfig was fixed up to use the new symbol as well. Tested on ARM RealView PB1176.

ARM: pmu: remove arm_pmu_type enumeration

2012-08-23T10:35:51+00:00

The arm_pmu_type enumeration was initially introduced to identify different PMU types in the system, the usual one being that on the CPU (ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.

ARM: mach-realview and mach-versatile: retire custom LED code

2012-08-01T03:22:04+00:00

This replaces the custom LED trigger code in mach-realview with some overarching platform code for the plat-versatile family that will lock down LEDs 2 thru 5 for CPU activity indication. The day we have 8 core ARM systems the plat-versatile code will have to become more elaborate. Tested on RealView PB11MPCore by invoking four different CPU hogs (yes > /dev/null&) and see the LEDs go on one at a time. They all go off as the hogs are killed. Tested on the PB1176 as well - just one activity led (led 2) goes on and off with CPU activity.
