2009-12-11OMAP4: Fix cpu detectionSantosh Shilimkar
This patch fixes the OMAP4430 cpu detection. The IC rev detection is done with hawkeye and rev. Note that rev does not map directly to defined processor revision numbers as ES1.0 uses value 0.It also fixes the SCM base address to read the correct ID_CODE register. Also the cpu_is_omap44xx() and cpu_is_omap443x() correctly populated instead of always being true Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-10-20omap: headers: Move remaining headers from include/mach to include/platTony Lindgren
Move the remaining headers under plat-omap/include/mach to plat-omap/include/plat. Also search and replace the files using these headers to include using the right path. This was done with: #!/bin/bash mach_dir_old="arch/arm/plat-omap/include/mach" plat_dir_new="arch/arm/plat-omap/include/plat" headers=$(cd $mach_dir_old && ls *.h) omap_dirs="arch/arm/*omap*/ \ drivers/video/omap \ sound/soc/omap" other_files="drivers/leds/leds-ams-delta.c \ drivers/mfd/menelaus.c \ drivers/mfd/twl4030-core.c \ drivers/mtd/nand/ams-delta.c" for header in $headers; do old="#include <mach\/$header" new="#include <plat\/$header" for dir in $omap_dirs; do find $dir -type f -name \*.[chS] | \ xargs sed -i "s/$old/$new/" done find drivers/ -type f -name \*omap*.[chS] | \ xargs sed -i "s/$old/$new/" for file in $other_files; do sed -i "s/$old/$new/" $file done done for header in $(ls $mach_dir_old/*.h); do git mv $header $plat_dir_new/ done Signed-off-by: Tony Lindgren <tony@atomide.com>
2009-10-19omap: Split OMAP2_IO_ADDRESS to L3 and L4Santosh Shilimkar
This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to reclaim more IO space. The omap_read*() and omap_write*() functions will work only over L4 address space. Current omap kernel stack uses these functions only to access registers over L4 io address space Note that these macros should only be used when ioremap does not work. Please use ioremap instead in all new code. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-08-15timekeeping: Move NTP adjusted clock multiplier to struct timekeeperMartin Schwidefsky
The clocksource structure has two multipliers, the unmodified multiplier clock->mult_orig and the NTP corrected multiplier clock->mult. The NTP multiplier is misplaced in the struct clocksource, this is private information of the timekeeping code. Add the mult field to the struct timekeeper to contain the NTP corrected value, keep the unmodifed multiplier in clock->mult and remove clock->mult_orig.

2009-05-28OMAP2/3: PM: push core PM code from linux-omapKevin Hilman
This patch is to sync the core linux-omap PM code with mainline. This code has evolved and been used for a while the linux-omap tree, but the attempt here is to finally get this into mainline. Following this will be a series of patches from the 'PM branch' of the linux-omap tree to add full PM hardware support from the linux-omap tree. Much of this PM core code was written by Jouni Hogander with significant contributions from Paul Walmsley as well as many others from Nokia, Texas Instruments and linux-omap community.

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.

2009-02-08[ARM] OMAP2 SDRC: separate common OMAP2/3 code from OMAP2xxx codePaul Walmsley
Separate SDRC code common to OMAP2/3 from mach-omap2/sdrc2xxx.c to mach-omap2/sdrc.c. Rename the OMAP2xxx-specific functions to use an 'omap2xxx' prefix rather than an 'omap2' prefix, and use "sdrc" in the function names rather than "memory." Mark several functions as static that should not be used outside the sdrc2xxx.c file. linux-omap source commit is bf1612b9d8d29379558500cd5de9ae0367c41fc4.

2008-09-05[ARM] omap: Fix IO_ADDRESS() macrosRussell King
OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies for use with __raw_{read|write}* for accessing registers. Therefore, these macros should return (void __iomem *) cookies, not integer values. Doing this improves typechecking, and means we can find those places where, eg, DMA controllers are incorrectly given virtual addresses to DMA to, or physical addresses are thrown through a virtual to physical address translation.

2008-04-14ARM: OMAP2: Change 24xx to use new register accessPaul Walmsley
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>
