[PATCH v6 0/9] clocksource/drivers/timer-atmel-tcb: add sama5d2 support

[Alexandre Belloni]

Hello,

This series mainly adds sama5d2 support where we need to avoid using
clock index 0 because that clock is never enabled by the driver.

There is also a rework of the 32khz clock handling so it is not used for
clockevents on 32 bit counter because the increased rate improves the
resolution and doesn't have any drawback with that counter width. This
replaces a patch that has been carried in the linux-rt tree for a while.

Changes in v6:
 - Added final Rob's Reviewed by, based on:
   https://lore.kernel.org/linux-arm-kernel/20200709210543.GA884561@bogus/
 - fixed the clockevent periodic rate

Changes in v5:
 - Rebased on top of v5.8-rc1
 - Added Rob's ack

Changes in v4:
 - Rework binding documentation

Changes in v3:
 - Moved the child node documentation to the parent documentation

Changes in v2:
 - Rebased on v5.7-rc1
 - Moved the binding documentation to its proper place
 - Added back the atmel,tcb-timer child node documentation
