This patches series adds a new driver for the timers found in the Mstar
MSC313e SoCs and newer. It adds a basic clocksource driver, the
corresponding devicetree bindings and its documentation.
Changes since v1:
- Make delay conditionnal for ARM, so it builds on all platforms
- Improved commit message for the timer driver
- MSC313E_TIMER is now silent and enabled by platform
- Updated msc313e_timer_setup() to make it safe
- Updated msc313e_timer_current_value() to make it safe
- Renamed the driver variant for ssd20xd to "sstar,ssd20xd-timer"
- Moved timer settings for the ssd202d from
mstar-infinity2m-ssd20xd.dtsi to mstar-infinity2m.dtsi.
- Select MSC313E_TIMER on mstar platforms
- Fixed wrong dt-bindings doc that included an rtc property (whoops!)
