[PATCH v2 0/4] dt-bindings: timer: exynos4210-mct: describe known hardware and its interrupts

[Krzysztof Kozlowski]

Hi,

Changes since v1:
1. Patch 1: Specify Tesla FSD interrupts.
2. New patch 4 for Tesla FSD.
3. Add review tags.

Merging/dependencies
====================
The dt-bindings (patch 1) can go via timer tree and I will take later DTS
patches via Samsung Soc.

Best regards,
Krzysztof

[PATCH v2 1/4] dt-bindings: timer: exynos4210-mct: describe known hardware and its interrupts

[Krzysztof Kozlowski]

Most of the Samsung Exynos SoCs use almost the same Multi-Core Timer
block, so only two compatibles were used so far (for Exynos4210 and
Exynos4412 flavors) with Exynos4210-one being used in most of the SoCs.
However the Exynos4210 flavor actually differs by number of interrupts.

Add new compatibles, maintaining backward compatibility with Exynos4210,
and constraints for number of interrupts.  This allows to exactly match
the Exynos MCT hardware.

[PATCH v2 2/4] ARM: dts: exynos: add a specific compatible to MCT

[Krzysztof Kozlowski]

One compatible is used for the Multi-Core Timer on most of the Samsung
Exynos SoCs, which is correct but not specific enough.  These MCT blocks
have different number of interrupts, so add a second specific
compatible to Exynos3250 and all Exynos5 SoCs.
