[PATCH v3 0/4] clocksource: Add MCT support for ARTPEC-8

From: Vincent Whitchurch
Date: Thu Apr 07 2022 - 03:44:49 EST


This series add supports for the timer block on ARTPEC-8. The block itself is
fully compatible with the existing exynos4210-mct driver. The ARTPEC-8 SoC
uses this block from two separate processors running Linux (AMP) so it needs
some extra code to allow this sharing.

v3:
- Split and rename devicetree properties
- Add vendor prefix to devicetree properties
- Change descriptions of properties to hopefully describe hardware
- Remove addition of more global variables to the driver

v2:
- The series is now rebased on top of Krzysztof's patch "dt-bindings: timer:
exynos4210-mct: describe known hardware and its interrupts".
- Combine the Kconfig change and the local timer change into one series
- Use devicetree property rather than module parameter for the local timer handling
- Add specific compatible with the correct number of interrupts.
