2014-09-22ARM: exynos: Move to generic PM domain DT bindingsTomasz Figa
This patch moves Exynos PM domain code to use the new generic PM domain look-up framework introduced in previous patches, thus also allowing the new code to be compiled with CONFIG_ARCH_EXYNOS.

2014-09-18arm/arm64: KVM: vgic: delay vgic allocation until init timeMarc Zyngier
It is now quite easy to delay the allocation of the vgic tables until we actually require it to be up and running (when the first vcpu is kicking around, or someones tries to access the GIC registers). This allow us to allocate memory for the exact number of CPUs we have. As nobody configures the number of interrupts just yet, use a fallback to VGIC_NR_IRQS_LEGACY.

2014-09-18arm/arm64: KVM: vgic: switch to dynamic allocationMarc Zyngier
So far, all the VGIC data structures are statically defined by the *maximum* number of vcpus and interrupts it supports. It means that we always have to oversize it to cater for the worse case. Start by changing the data structures to be dynamically sizeable, and allocate them at runtime. The sizes are still very static though. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>

2014-09-19ARM: pxa3xx: provide specific platform_devices for all ssp portsDaniel Mack
Currently, devices for SSP ports 1, 2 and 3 are registered as compatible devices to pxa27x-ssp. While the actual IP core is comparable, there are some subtle differences which users of the SSP ports address by looking at the 'type' field. By registering devices of type 'pxa27x-ssp', this 'type' field is incorrectly set to PXA27x_SSP which confuses the users. To fix this, provide specific ssp port plaform devices which use 'pxa3xx-ssp' as driver name, an instantiate them from pxa3xx.c.
