Also remove board-omap3beagle.h that is not included anywhere, and move protoype for voiceblue_reset() from board-voiceblue.h to system.h. After this patch there are still board-ams-delta.h, board-sx1.h and board-voiceblue.h that export some functions. These could be removed if the functions were moved under drivers.

2009-03-04ARM: OMAP: sched_clock() correctedAaro Koskinen
After my OMAP3 board has been running for a while, I'm seeing weird latency traces like this: sh-1574 0d.h2 153us : do_timer (tick_do_update_jiffies64) sh-1574 0d.h2 153us : update_wall_time (do_timer) sh-1574 0d.h2 153us!: omap_32k_read (update_wall_time) sh-1574 0d.h2 1883us : update_xtime_cache (update_wall_time) sh-1574 0d.h2 1883us : clocksource_get_next (update_wall_time) sh-1574 0d.h2 1883us+: _spin_lock_irqsave (clocksource_get_next) and after a while: sh-17818 0d.h3 153us : do_timer (tick_do_update_jiffies64) sh-17818 0d.h3 153us : update_wall_time (do_timer) sh-17818 0d.h3 153us!: omap_32k_read (update_wall_time) sh-17818 0d.h3 1915us : update_xtime_cache (update_wall_time) sh-17818 0d.h3 1915us+: clocksource_get_next (update_wall_time) sh-17818 0d.h3 1945us : _spin_lock_irqsave (clocksource_get_next) Turns out that sched_clock() is using cyc2ns(), which returns NTP adjusted time. The sched_clock() frequency should not be adjusted. The patch deletes omap_32k_ticks_to_nsecs() and rewrites sched_clock() to do the conversion using the constant multiplier.

2009-01-29ARM: OMAP: Fix McBSP spin_lock deadlockStanley.Miao
A spin_lock deadlock will occur when omap_mcbsp_request() is invoked. omap_mcbsp_request() \- clk_enable(mcbsp->clk) [takes and holds clockfw_lock] \- omap2_clk_enable() \- _omap2_clk_enable() \- omap_mcbsp_clk_enable() \- clk_enable(child clock) [tries for clockfw_lock again] mcbsp_clk is a virtual clock and it comprises several child clocks. when enable mcbsp_clk in omap_mcbsp_request(), the enable function of mcbsp_clk will enable its child clocks, then the deadlock occurs. The solution is to remove the virtual clock and enable these child clocks in omap_mcbsp_request() directly.

This patch removes old platform devices. Alsa should now be using the ASoC driver. For boards not yet using ASoC, please see sound/soc/omap/osk5912.c. Add dummy aic23_power_up and aic23_power_down functions for 770 to keep things compiling. Remove references to omap_gpio_switch, and unused h2_nand_dev_ready function.

2009-01-15ARM: OMAP: Fix ASoC by enabling writes to XCCR and RCCR McBSP registers, v3Tony Lindgren
This patch enables writing to McBSP Transmit Configuration Control Register (XCCR) and Receive Configuration Control Register (RCCR) for 2430/34xx platforms. It also adds XCCR, RCCR entries in McBSP register configuration structure and bit definitions for both registers. If we enable the writing to CCR registers for 2430/34xx and don't set the default values (setting 0 as a consequence) in ASoC driver, the Transmit/Receive DMA mode gets disabled and the the transmission/reception doesn't happen, ending with a "write error: Input/Output error" when playing with 'aplay'. Also define dummy CCR registers for omap1. Cc: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Misael Lopez Cruz <x0052729@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2008-12-10ARM: OMAP2: skip unnecessary TLDR write during non-autoreload for gptimerPaul Walmsley
The GPTIMER TLDR register does not need to be written if the GPTIMER is not in autoreload mode. This is the usual case for dynamic tick-enabled kernels. Simulation data indicate that skipping the read that occurs as part of the write should save at least 300-320 ns for each GPTIMER1 timer reprogram. (This assumes L4-Wakeup is at 19MHz and GPTIMER write posting is enabled.) Skipping the write itself probably won't have much impact since it should be posted on the OCP interconnect. Tested on 2430SDP and 3430SDP.
