ARM: integrator: move restart to the device tree Using the augmented reset driver for the Versatile family, we can move the reset handling for the Integrator out of the machine. We add a "syscon" attribute to the core module, and access the syscon registers using this handle. We need to select SYSCON, POWER, POWER_RESET and POWER_RESET_VERSATILE in order for the restart functionality to always be available on all systems (it should not be optional).

Support for ARM's Integrator platform.
Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

config ARCH_CINTEGRATOR

config INTEGRATOR_IMPD1
ARM: integrator: fix section mismatch problem This addresses a section mismatch problem in the IM-PD1 driver in the Integrator/AP. The IM-PD1 contains a VIC interrupt controller and therefore the driver calls vic_init_cascaded() which is marked __init as irqchips are simply not hot-pluggable and specifically the VIC is assumed to initiate only on boot. However the module driver model of the Integrator LM bus assumes that logic tile drivers can be probed at runtime. This is not really the case for IM-PD1: these tiles are detected at boot and they cannot be plugged into a running system. Before this patch it is of course possible to modprobe them later. By first forcing the IM-PD1 to bool we make sure this driver gets compiled into the kernel, and we know it will be probed only at boot time when the tiles are detected, so we can tag its probe function __init_refok as we know it won't be called after boot now, and the section mismatch problem goes away. As a side effect, sysfs binding from userspace becomes impossible, so we tag the driver to suppress the bind/unbind sysfs attributes.

The IM-PD1 is an add-on logic module for the Integrator which
allows ARM(R) Ltd PrimeCells to be developed and evaluated.
The IM-PD1 can be found on the Integrator/PP2 platform.
To compile this driver as a module, choose M here: the
module will be called impd1.
