From 469d30448dad13600cdd246024f9db8e80614c45 Mon Sep 17 00:00:00 2001 From: Mikael Pettersson Date: Thu, 29 Oct 2009 11:46:54 -0700 Subject: iop: clockevent support This updates the IOP platform to expose the interrupting timer 0 as a clockevent object. The timer interrupt handler is changed to call the clockevent ->event_handler() instead of timer_tick(), and ->set_next_event() and ->set_mode() operations are added to allow the mode of the timer to be updated (required for ONESHOT/NOHZ mode). Timer 0 must now be properly initialised, which requires a new write_tcr0() function from the mach-specific code. The mode of timer 0 must be read at the start of ->set_mode(), which requires a new read_tmr0() function from the mach- specific code. Initial setup of timer 0 is also rewritten to be more robust. Tested on n2100, compile-tested for all plat-iop machines.
