Migrate microblaze 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. We weren't doing anything in ->set_mode(RESUME or ONESHOT) and so tick_resume() set_state_oneshot() aren't implemented. Cc: Michal Simek <monstr@monstr.eu> Cc: "David S.

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().

Migrate timer-imx-gpt 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. 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. Cc: Shawn Guo <shawn.guo@linaro.org> Cc: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by:

Since the removal of the r8a7740 legacy SoC code in commit 44d88c75 ("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. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry. Signed-off-by:

Commit d2348fb6 ("tick: Dynamically set broadcast irq affinity") adds one excellent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the interrupt affinity of the broadcast interrupt to the cpu which has the earliest expiry time. This patch adds CLOCK_EVT_FEAT_DYNIRQ flag to avoid unnecessary wakeups and IPIs when the dw_apb_timer is used as broadcast timer. A simple test: ~ # rm /tmp/test.sh ~ # cat > /tmp/test.sh cat /proc/interrupts for i in `seq 10` ; do sleep $i; done cat /proc/interrupts ~ # chmod +x /tmp/test.sh ~ # taskset 0x2 /tmp/test.sh without the patch: CPU0 CPU1 27: 115 36 GIC 27 arch_timer 45: 62 0 GIC 45 mmc0 160: 88 0 interrupt-controller 8 timer 227: 0 0 interrupt-controller 4 f7e81400.i2c 228: 0 0 interrupt-controller 5 f7e81800.i2c 229: 0 0 interrupt-controller 7 dw_spi65535 230: 0 0 interrupt-controller 21 f7e84000.i2c 231: 0 0 interrupt-controller 20 f7e84800.i2c 265: 445 0 interrupt-controller 8 serial IPI0: 0 0 CPU wakeup interrupts IPI1: 0 11 Timer broadcast interrupts IPI2: 56 104 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 0 4 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 25 27 IRQ work interrupts IPI7: 0 0 completion interrupts IPI8: 0 0 CPU backtrace Err: 0 CPU0 CPU1 27: 115 38 GIC 27 arch_timer 45: 62 0 GIC 45 mmc0 160: 160 0 interrupt-controller 8 timer 227: 0 0 interrupt-controller 4 f7e81400.i2c 228: 0 0 interrupt-controller 5 f7e81800.i2c 229: 0 0 interrupt-controller 7 dw_spi65535 230: 0 0 interrupt-controller 21 f7e84000.i2c 231: 0 0 interrupt-controller 20 f7e84800.i2c 265: 514 0 interrupt-controller 8 serial IPI0: 0 0 CPU wakeup interrupts IPI1: 0 83 Timer broadcast interrupts IPI2: 56 104 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 0 4 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 25 46 IRQ work interrupts IPI7: 0 0 completion interrupts IPI8: 0 0 CPU backtrace Err: 0 cpu0 get 160-88=72 timer interrupts, CPU1 got 83-11=72 broadcast timer IPIs So, overall system got 72+72=144 wake ups and 72 broadcast timer IPIs With the patch: CPU0 CPU1 27: 107 37 GIC 27 arch_timer 45: 62 0 GIC 45 mmc0 160: 66 7 interrupt-controller 8 timer 227: 0 0 interrupt-controller 4 f7e81400.i2c 228: 0 0 interrupt-controller 5 f7e81800.i2c 229: 0 0 interrupt-controller 7 dw_spi65535 230: 0 0 interrupt-controller 21 f7e84000.i2c 231: 0 0 interrupt-controller 20 f7e84800.i2c 265: 311 0 interrupt-controller 8 serial IPI0: 0 0 CPU wakeup interrupts IPI1: 2 4 Timer broadcast interrupts IPI2: 58 100 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 0 4 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 21 24 IRQ work interrupts IPI7: 0 0 completion interrupts IPI8: 0 0 CPU backtrace Err: 0 CPU0 CPU1 27: 107 39 GIC 27 arch_timer 45: 62 0 GIC 45 mmc0 160: 69 75 interrupt-controller 8 timer 227: 0 0 interrupt-controller 4 f7e81400.i2c 228: 0 0 interrupt-controller 5 f7e81800.i2c 229: 0 0 interrupt-controller 7 dw_spi65535 230: 0 0 interrupt-controller 21 f7e84000.i2c 231: 0 0 interrupt-controller 20 f7e84800.i2c 265: 380 0 interrupt-controller 8 serial IPI0: 0 0 CPU wakeup interrupts IPI1: 3 6 Timer broadcast interrupts IPI2: 60 100 Rescheduling interrupts IPI3: 0 0 Function call interrupts IPI4: 0 4 Single function call interrupts IPI5: 0 0 CPU stop interrupts IPI6: 21 45 IRQ work interrupts IPI7: 0 0 completion interrupts IPI8: 0 0 CPU backtrace Err: 0 cpu0 got 69-66=3, cpu1 got 75-7=68 timer interrupts. cpu0 got 3-2=1 broadcast timer IPIs, cpu1 got 6-4=2 broadcast timer IPIs.

Both these are done with a single write operation now. Cc: Linus Walleij <linus.walleij@linaro.org> Signed-off-by:

The debug prints are called from mxs_irq_clear() now based on the state-name passed to it. The printed name will be same for shutdown and resume states as they use the same callback pointer.
