[PATCH v7 0/2] Add the driver for Intel Keem Bay SoC timer block

From: Shruthi Sanil <redacted>

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.

Changes since v6:
- Removed the unused compatible string from the mfd device node
  to fix the error thrown by the make dt-binding command.

Changes since v5:
- Created a MFD device for the common configuration register
  in the device tree bindings.
- Updated the timer driver with the MFD framework to access the
  common configuration register.

Changes since v4:
- Updated the description in the device tree bindings.
- Updated the unit address of all the timers and counter
  in the device tree binding.

Changes since v3:
- Update in KConfig file to support COMPILE_TEST for Keem Bay timer.
- Update in device tree bindings to remove status field.
- Update in device tree bindings to remove 64-bit address space for
  the child nodes by using non-empty ranges.

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.
