[PATCH v2 0/2] clocksource: Add support for Oxford Semiconductor RPS Dual Timer

[Neil Armstrong]

Adds driver for the Oxford Semiconductor RPS Dual Timer as base of the OX810SE
clock tick event and sched clock source.

This driver was posted with the initial OX810SE platform patchset at :
http://lkml.kernel.org/r/1457005210-18485-5-git-send-email-narmstrong@baylibre.com
and
http://lkml.kernel.org/r/1457005210-18485-6-git-send-email-narmstrong@baylibre.com

But since the SP804 was very similar, I decided to adapt it for OX810SE usage.
For some reasons, the SP804 has a lot of legacy code for non-dt, non-multiarch
platforms and needs a complete rewrite.
For now, this adds a dedicated driver with the same bindings as intended for SP804.

Changes since v1 at http://lkml.kernel.org/r/1464688198-9655-1-git-send-email-narmstrong@baylibre.com :
- fix timer_shutdown behaviour
- clean up period calculation
