ARM: mxs: move timer driver into drivers/clocksource

2013-04-01T08:30:03+00:00

Move mxs timer driver into drivers/clocksource as mxs_timer.c. Signed-off-by: Shawn Guo

ARM: mxs: select STMP_DEVICE and use it for timer code

2013-04-01T08:30:02+00:00

Select STMP_DEVICE and in timer code replace mxs_reset_block() with stmp_reset_block(), use STMP_OFFSET_REG_SET/CLR to replace __mxs_setl/clrl. As the result, and includsion can be removed from timer.c now. Signed-off-by: Shawn Guo

ARM: mxs: remove cpu_is_mx23() call from timer code

2013-04-01T08:30:02+00:00

Remove cpu_is_mx23() call from timer code by using of_device_is_compatible() instead. Signed-off-by: Shawn Guo

ARM: mxs: get timrot base address from device tree

2013-04-01T08:30:02+00:00

Instead of using static defines, it gets timrot base address with mapping from device tree. Signed-off-by: Shawn Guo

ARM: mxs: look up timrot clock from device tree

2013-04-01T08:30:02+00:00

Change call clk_get_sys() to of_clk_get() to look up timrot clock from device tree, so that the clk_register_clkdev() call for timrot can be saved in clock driver. Signed-off-by: Shawn Guo

ARM: mxs: use CLKSRC_OF helper to initialize timer

2013-04-01T08:30:01+00:00

Select CLKSRC_OF and use clocksource_of_init() to initialize timer, so that the call to mxs_timer_init() in clock driver can be removed. Signed-off-by: Shawn Guo

ARM: mxs: decrease mxs_clockevent_device.min_delta_ns to 2 clock cycles

ARM: mxs: use apbx bus clock to drive the timers on timrotv2

2013-02-05T03:19:46+00:00

timer resolution of ~32us is pretty low. v2 has 32bits resolution, so we have quite some headroom, and can use the 24MHz clock. v1 has only 16bits, so we only increase v2. So we just exchange the timrot clock in imx28. On imx23 we have timrotv1 and everything stays the same. Signed-off-by: Torben Hohn Signed-off-by: Shawn Guo

ARM: use clockevents_config_and_register() where possible

2013-01-14T18:12:42+00:00

The clockevent core is able to figure out the best mult and shift, calculate min_delta_ns and max_delta_ns, with the necessary info passed into clockevents_config_and_register(). Use this combined configure and register function where possible to make the codes less error prone and gain some positive diff stat.

ARM: mxs: Setup scheduler clock

2012-11-12T01:27:30+00:00

Setup scheduler clock on ARM MXS platforms with a 32-bit timrot such as i.MX28. This allows the scheduler to use sub-jiffy resolution. The corresponding change for 16-bit v1 timrots is not possible at the moment due to rounding issues with clock values wrapping faster than once per several seconds in the common ARM platform code.
