* 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.
|
|
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).

Replace hex flags with human-readable symbols from arm-gic.h header
which makes it easier to recognize what is configured.

Add RTC source clock as Exynos7 needs source (32.768KHz) clock
for RTC block. Without this currently S3C RTC driver probe is broken
on this SoC.

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.
The commit should not bring any visible functional change.

This patch enables HS200 mode operation on Exynos7 based
Espresso board.
This also removes _broken-cd_ property as per mmc binding documentation
which says one of the properties between broken-cd and non-removable
should be used. And we already use _non-removable_ as emmc is mounted
on the board which is a non-removable device.
