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/[email protected] and http://lkml.kernel.org/r/[email protected] 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 v2 at http://lkml.kernel.org/r/[email protected] : - Add Kconfig text with COMPILE_TEST options - Add CLKSRC_OF select - Add clean rollback of init in case of error - Prepare for clocksource and clockevent rollback by returning an int value - Switch kzalloc WARN_ON to a pr_err Changes since v1 at http://lkml.kernel.org/r/[email protected] : - fix timer_shutdown behaviour - clean up period calculation Neil Armstrong (2): clocksource: Add Oxford Semiconductor RPS Dual Timer dt-bindings: clocksource: Add Add Oxford Semiconductor RPS Timer bindings .../devicetree/bindings/timer/oxsemi,rps-timer.txt | 17 ++ drivers/clocksource/Kconfig | 7 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-oxnas-rps.c | 290 +++++++++++++++++++++ 4 files changed, 315 insertions(+) create mode 100644 Documentation/devicetree/bindings/timer/oxsemi,rps-timer.txt create mode 100644 drivers/clocksource/timer-oxnas-rps.c -- 1.9.1
