Subject: [PATCH v2 0/2] Add drivers for Intel Keem Bay SoC timer block

From: Vijayakannan Ayyathurai <vijayakannan.ayyathurai@...el.com>

Hi,

This patch set adds the driver for Intel Keem Bay SoC timer block, which
contains 32-bit general purpose timers, a 64 bit free running counter.

Patch 1 holds the Device Tree binding documentation and
Patch 2 holds the Device Driver for clocksource and clockevent.

It was tested on the Keem Bay evaluation module board.

Thanks,
Vijay

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.
