Series clocksource: Add MCT support for ARTPEC-8 | expand


Vincent Whitchurch April 7, 2022, 7:44 a.m. UTC
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.

- 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

- 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.
