* ARM: OMAP2: Add common clock framework for 24xx and 34xxPaul Walmsley2008-04-14
| | | | | | | | | | This patch adds a common clock framework for 24xx and 34xx. Note that this patch does not add it to Makefile until in next patch. Some functions are modified from earlier 24xx clock framework code. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2: Move clock.c to clock24xx.cPaul Walmsley2008-04-14
| | | | | | | | | | | This patch moves clock.h to clock24xx.c to make room for adding common clock code for 24xx and 34xx. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP2: Remove old 24xx PM codeTony Lindgren2008-04-14
| | | | | | | | | | | This patch removes old 24xx PM code that does not really work for sleep states, and uses old power management register access. Working PM code will be added later. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2: Change 24xx to use new register accessPaul Walmsley2008-04-14
| | | | | | | | | | | | | | | | | | | This patch changes 24xx to use new register access, except for clock framework. Clock framework register access will get updates in the next patch. Note that board-*.c files change GPMC (General Purpose Memory Controller) access to use gpmc_cs_write_reg() instead of accessing the registers directly. The code also uses gpmc_fck instead of it's parent clock core_l3_ck for GPMC clock. The H4 board file also adds h4_init_flash() function, which specify the flash start and end addresses. Also note that sleep.S removes some unused registers addresses. Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP2: Add common register access for 24xx and 34xxPaul Walmsley2008-04-14
| | | | | | | | | | | This patch adds common register access for 24xx and 34xx power and clock management in order to share code between 24xx and 34xx. Only change USB platform init code to use new register access, other access will be changed in later patches.

* ARM: OMAP2: Clean-up mux codeTony Lindgren2008-04-14
| | | | | | | | | | | | | Misc clean-up for the mux code and remove some unnecessary ifdefs. Patch changes debug function so it can be used on both 24xx and 34xx. Changes are mostly for omap2, but patch also cleans up some omap1 and common mux code. Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP: TimerMPU: Remove MPU-timer based sched_clock()Kevin Hilman2008-04-14
| | | | | | | | | | | | | Remove MPU-timer based sched_clock() in favor of the common one based on 32k sync timer which works across all OMAP1/2/3 platforms. Using 32k based one also gives a valid sched_clock() very early in the boot process. Signed-off-by: Kevin Hilman <khilman@mvista.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP: TimerMPU: Remove unused cycles-to-nsec conversionsKevin Hilman2008-04-14

* ARM: OMAP1: Timer32K: Fix timer32K for clockevents and clean it upTony Lindgren2008-04-14
| | | | | | | | | This patch fixes timer32k for clockevents and syncs it with linux-omap tree. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP: Timer32K: Move timer32k to mach-omap1Kevin Hilman2008-04-14
| | | | | | | | | | Move now OMAP1-specific timer32k code to mach-omap1 since OMAP2/3 32k timers are done in gptimer code. Signed-off-by: Kevin Hilman <khilman@mvista.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP: Timer32K: Move 32k-based sched_clock() to common codeKevin Hilman2008-04-14
| | | | | | | | | | | | | | | | Since 32k timer code is moving to OMAP1 specific dir, move the 32k-based sched_clock() into common code where it is based on the 32k sync counter and can be used even when using MPU timer. While moving, change the ticks-to-nsecs conversion to use the helper functions provided by clocksource.h. Also removed the unused ticks_to_usec, leaving only ticks_to_nsec.

* ARM: OMAP: Timer32K: Re-organize duplicated 32k-timer codeKevin Hilman2008-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by setting the source to be the 32k clock instead of sys_clk. This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp code. Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based clocksource is not used. Instead the default 32k sync counter is used as the clocksource (see the clocksource in plat-omap/common.c.) This is important for sleep/suspend so there is a valid counter during sleep. Note that the suspend/sleep code needs fixing to check for overflows of this counter. In addition, the OMAP2/3 details are removed from timer32k.c leaving that with only OMAP1 specifics. A follow-up patch will move it from plat-omap common code to mach-omap1.

* ARM: OMAP: Allow registering pin mux functionTony Lindgren2008-04-14
| | | | | | | | | | | | | This patch changes pin multiplexing init to allow registering custom function. The omap_cfg_reg() func will be split into omap processor specific functions in later patch. This is done to make adding omap3 pin multiplexing easier. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP: use edge/level handlers from generic IRQ frameworkKevin Hilman2008-04-14
| | | | | | | | | | | | | | | | Currently, the GPIO interrupt handling is duplicating some of the work done by the generic IRQ handlers (handle_edge_irq, handle_level_irq) such as detecting nesting, handling re-triggers etc. Remove this duplication and use generic hooks based on IRQ type. Using generic IRQ handlers ensures correct behavior when using threaded interrupts introduced by the -rt patch.

* ARM: OMAP: Clear level-triggered GPIO interrupts in unmask hookKevin Hilman2008-04-14
| | | | | | | | | | | | | The clearing was moved to the unmask hook because it is known to run after the interrupt handler has actually run. Before this patch, if interrupts are threaded, the clearing/unmasking of level triggered interrupts would be done before the threaded handler actually ran.
