2016-11-15arm64: dts: Add ARM PMU node for exynos7Alim Akhtar1-4/+14
This patch adds ARM Performance Monitor Unit dt node for exynos7. PMU provides various statistics on the operation of the CPU and memory system at runtime, which are very useful when debugging or profiling code. This enables the same.

2016-11-03arm64: dts: exynos: Fix invalid GIC interrupt flags in exynos7Krzysztof Kozlowski2-38/+51
Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and generates an error: genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68) The GIC requires shared interrupts to be edge rising or level high. Platform declares support for both. Arbitrarily choose level high everywhere hoping it will work on each platform.

2016-09-14Merge branch 'dt/irq-fix' into next/dt64Arnd Bergmann1-4/+4
* dt/irq-fix: arm64: dts: Fix broken architected timer interrupt trigger This resolves a non-obvious conflict between a bugfix from v4.8 and a cleanup for the exynos7 platform.
2016-09-14arm64: dts: Fix broken architected timer interrupt triggerMarc Zyngier1-4/+4
The ARM architected timer specification mandates that the interrupt associated with each timer is level triggered (which corresponds to the "counter >= comparator" condition). A number of DTs are being remarkably creative, declaring the interrupt to be edge triggered. A quick look at the TRM for the corresponding ARM CPUs clearly shows that this is wrong, and I've corrected those. For non-ARM designs (and in the absence of a publicly available TRM), I've made them active low as well, which can't be completely wrong as the GIC cannot disinguish between level low and level high. The respective maintainers are of course welcome to prove me wrong. While I was at it, I took the liberty to fix a couple of related issue, such as some spurious affinity bits on ThunderX, and their complete absence on ls1043a (both of which seem to be related to copy-pasting from other DTs).

The ARMv8 Exynos family SoCs in Linux kernel are currently: - Exynos5433 (controlled by ARCH_EXYNOS), - Exynos7 (controlled by ARCH_EXYNOS7). It duplicates Kconfig symbols unnecessarily, so consolidate them into one ARCH_EXYNOS. Future SoCs could fall also under the ARCH_EXYNOS symbol.
