From: Shruthi Sanil <shruthi.sanil@xxxxxxxxx> 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 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.
