Cover letter [PATCH 0/5 v3] S3C / S5PC100: add clockevent/clocksource support
This series of patches converts the s3c and s5pc100 timer driver to the clocksource/clockevent API.
I made some test on a mini2440 board and I had to reduce timers frequency to 1MHz in order to produce a timer's overflow every 64ms. Initial timer's frequency (8,45MHz) provide only 7ms between each overflow. It is not enough.
As timers were previously used to produce an IRQ at 200Hz, some board (Osiris, Anubis board) use an external 12MHz signal to clock the timers (tclk1). So, I changed their configuration to select internal pclk clock instead, but I can't test it.
Since clockevent/clocksource API becomes available, we can use High Resolution Timer and Tickless mode.
Most of the work is already done in s5p-time.c (renamed samsung-time.c). I added some #define for s3c24xx and s5pc100 case.
