Subject: [PATCH v3 0/2] Add the driver for Intel Keem Bay SoC timer block

From: Shruthi Sanil <shruthi.sanil@...el.com>

The timer block supports 1 64-bit free running counter
and 8 32-bit general purpose timers.

Patch 1 holds the device tree binding documentation.
Patch 2 holds the device driver.

This driver is tested on the Keem Bay evaluation module board.

I would like to inform that, I would be taking the ownership
of this patch series from this version.

Changes since v2:
- Add multi timer support.
- Update in the device tree binding to support multi timers.
- Code optimization.

Changes since v1:
- Add support for KEEMBAY_TIMER to get selected through Kconfig.platforms.
- Add CLOCK_EVT_FEAT_DYNIRQ as part of clockevent feature.
- Avoid overlapping reg regions across 2 device nodes.
- Simplify 2 device nodes as 1 because both are from same IP block.
- Adapt the driver code according to the new simplified devicetree.

  dt-bindings: timer: Add bindings for Intel Keem Bay SoC Timer
  clocksource: Add Intel Keem Bay timer support
