* clockevents/drivers/timer-sp804: Migrate to new 'set-state' interfaceViresh Kumar2015-08-101-27/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate timer-sp 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. There are few more changes worth noticing: - The clockevent device was disabled by writing: 'TIMER_CTRL_32BIT | TIMER_CTRL_IE' to ctrl register earlier. i.e. by un-setting the TIMER_CTRL_ENABLE bit. Its done by writing zero now and should have the same effect. - For shutdown and resume we were writing the same value twice to the register (to disable the timer), which is fixed now. - Switching to oneshot mode was divided into two parts earlier: - Firstly set_mode() was writing: 'TIMER_CTRL_32BIT | TIMER_CTRL_IE | TIMER_CTRL_ONESHOT' to ctrl register (device not enabled yet) - Then sp804_set_next_event() was enabling the device by writing 'readl(ctrl) | TIMER_CTRL_ENABLE' to the ctrl register. This was unnecessarily complicated. - Change this to: Stop device on set_state_oneshot and configure it in sp804_set_next_event().

This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. Also drop: - 'imx_timer.cem': It was caching the last state of the clockevent device. The same behavior can be achieved by using clockevents state helpers. These helpers are only required for oneshot mode as shutdown/resume wouldn't be done twice by the core. - 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore by drivers. The prints are modified to print the set-state functions name now to debug the driver.

| | | | | | | | | | | | | Since the removal of the r8a7740 legacy SoC code in commit 44d88c754e57a6d9 ("ARM: shmobile: Remove legacy SoC code for R-Mobile A1"), all former users of the "sh-cmt-48-gen2" platform device name are only supported in generic DT-only ARM multi-platform builds.
