2015-12-15h8300: Rename ctlr_out/in[bwl] to raw_read/write[bwl]Daniel Lezcano1-17/+17
For the sake of consistency, let rename all ctrl_out/in calls to the write/read calls so we have the same API consistent with the other architectures hence open the door for the increasing of the test compilation coverage. The unsigned long coercive cast is removed because all variables are set to the right type "void __iomem *". Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-12-15clocksource/drivers/h8300_timer8: Retrieve the clock rate at init timeDaniel Lezcano1-12/+14
The current code retrieves the rate value when the timer is enabled which occurs each time a timer is re-armed. Except if the clock frequency has changed magically I don't see why this should be done each time. Retrieve the clock rate value at init time only.

2015-12-15clocksource/drivers/h8300_timer8: Remove irq and lock legacy codeDaniel Lezcano1-16/+0
The time framawork takes care of disabling the interrupts and takes a lock to prevent races. Remove the legacy code in the driver taking care of the races. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-12-15clocksource/drivers/h8300_timer8: Remove pointless irq re-entrant safe codeDaniel Lezcano1-9/+6
The current code assumes the interrupt function is re-entrant. That is not correct. An interrupt handler is never invoked concurrently. The interrupt line is masked on all processors. Remove the chewing flags in the code. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-12-15clocksource/drivers/h8300_timer8: Fix irq return value checkDaniel Lezcano1-1/+1
The value returned in case of error for the 'irq_of_parse_and_map' function is zero in case of error. Fix the check in the init code. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-12-15clocksource/drivers/h8300_timer8: Remove PERIODIC and ONESHOT macroDaniel Lezcano1-7/+4
Specify the delta as parameter for the timer8_clock_event_start function instead of using a macro to tell PERIODIC or ONESHOT. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>

2015-12-15clocksource/drivers/h8300_timer8: Fix compilation error with dev_warnDaniel Lezcano1-1/+1
The dev_warn is using the platform driver which was removed in the previous patch. Let's replace dev_warn by pr_warn. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-12-15clocksource/drivers/h8300: Cleanup startup and remove module code.Yoshinori Sato1-99/+51
Remove some legacy code and replace it by the clksrc-of code. Do some cleanup and code consolidation. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-10-15clocksource/drivers/h8300_*: Remove unneeded memset()sAlexey Klimov1-1/+0
Memory for timer16_priv, timer8_priv and tpu_priv structs is allocated by devm_kzalloc() in corresponding probe functions of drivers. No need to zero it one more time. Signed-off-by: Alexey Klimov <alexey.klimov@linaro.org> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
2015-08-10clockevents/drivers/h8300_timer8: Migrate to new 'set-state' interfaceViresh Kumar1-23/+28
Migrate h8300_timer8 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.
