With the upcoming WDT patches OMAP_WDT_BASE is no longer needed in devices.c. Revert some earlier omap3 changes to avoid merge conflicts with the WDT patches. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-10-14[ARM] 5305/1: ARM: OMAP: Fix compile of McBSP by removing unnecessary checkTony Lindgren
Recent McBSP patches changed to allocating devices dynamically and the check for OMAP_MAX_MCBSP_COUNT became unnecessary. The check for OMAP_MAX_MCBSP_COUNT should have been removed with the earlier McBSP patches in devices.c but was accidentally left out.

Also do following changes that make 34xx support usable: - Remove unused sram.c functions for 34xx - Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally in entry-macro.S - Update mach-omap2/io.c to support 2420, 2430, and 34xx - Also merge in 34xx GPMC changes to add fields wr_access and wr_data_mux_bus from Adrian Hunter - Remove memory initialization call omap2_init_memory() until until more generic memory initialization patches are posted. It's OK to rely on bootloader initialization until then.

Don't use __init but __devinit to define probe function. A pointer to omap_mcbsp_probe is passed to the core via platform_driver_register and so the function must not disappear when the init code is freed. Using __init and having HOTPLUG=y the following probably oopses: echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/unbind echo -n omap-mcbsp.1 > /sys/bus/platform/driver/omap-mcbsp/bind While at it move the remove function to the .devexit.text section.

2008-10-06ARM: OMAP2: Move sleep.S into sleep24xx.STony Lindgren
Some register offsets are different for 242x and 243x. This will allow compiling sleep code for both chips into the same kernel. Pass the addresses for SDRC_DDLA_CTRL and SDRC_POWER to the omap24xx_cpu_suspend instead of loading the values since the only. Also fix a bug to call omap2_sram_suspend with the value of SDRC_DLLA_CTRL instead of the address as that's what omap24xx_cpu_suspend expects to determine between DDR and SDR. This bug has not been noticed as the boards seem to have DDR instead of SDR. Note that some PM patches are still missing. The PM patches will be added later on once the base files are in sync with linux-omap tree. Signed-off-by: Tony Lindgren <tony@atomide.com>

Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-09-05[ARM] omap: fix inappropriate casting in gpio.cRussell King
gpio.c wilfully casts physical addresses to void __iomem * and then fixes them up at runtime using: bank->base = IO_ADDRESS(bank->base); where accesses prior to this fixup are via omap_read/omap_write, and after are by __raw_read/__raw_write. This doesn't lend itself to static checking, nor to easy understanding of the code. And so, OMAP_MPUIO_BASE gets to be the right type - integer like since it's a physical address, not a MMIO pointer.

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.

2008-09-02[x86] Fix TSC calibration issuesThomas Gleixner
Larry Finger reported at http://lkml.org/lkml/2008/9/1/90: An ancient laptop of mine started throwing errors from b43legacy when I started using 2.6.27 on it. This has been bisected to commit bfc0f59 "x86: merge tsc calibration". The unification of the TSC code adopted mostly the 64bit code, which prefers PMTIMER/HPET over the PIT calibration. Larrys system has an AMD K6 CPU. Such systems are known to have PMTIMER incarnations which run at double speed. This results in a miscalibration of the TSC by factor 0.5. So the resulting calibrated CPU/TSC speed is half of the real CPU speed, which means that the TSC based delay loop will run half the time it should run. That might explain why the b43legacy driver went berserk. On the other hand we know about systems, where the PIT based calibration results in random crap due to heavy SMI/SMM disturbance. On those systems the PMTIMER/HPET based calibration logic with SMI detection shows better results. According to Alok also virtualized systems suffer from the PIT calibration method. The solution is to use a more wreckage aware aproach than the current either/or decision. 1) reimplement the retry loop which was dropped from the 32bit code during the merge. It repeats the calibration and selects the lowest frequency value as this is probably the closest estimate to the real frequency 2) Monitor the delta of the TSC values in the delay loop which waits for the PIT counter to reach zero. If the maximum value is significantly different from the minimum, then we have a pretty safe indicator that the loop was disturbed by an SMI. 3) keep the pmtimer/hpet reference as a backup solution for systems where the SMI disturbance is a permanent point of failure for PIT based calibration 4) do the loop iteration for both methods, record the lowest value and decide after all iterations finished. 5) Set a clear preference to PIT based calibration when the result makes sense. The implementation does the reference calibration based on HPET/PMTIMER around the delay, which is necessary for the PIT anyway, but keeps separate TSC values to ensure the "independency" of the resulting calibration values. Tested on various 32bit/64bit machines including Geode 266Mhz, AMD K6 (affected machine with a double speed pmtimer which I grabbed out of the dump), Pentium class machines and AMD/Intel 64 bit boxen.

2008-09-02Un-break printk strings in x86 PCI probing codeLinus Torvalds
Breaking lines due to some imaginary problem with a long line length is often stupid and wrong, but never more so when it splits a string that is printed out into multiple lines. This really ended up making it much harder to find where some error strings were printed out, because a simple 'grep' didn't work. I'm sure there is tons more of this particular idiocy hiding in other places, but this particular case hit me once more last week. So fix it.

BAR, v3" This reverts commit a2bd7274b47124d2fc4dfdb8c0591f545ba749dd. It wasn't really right to begin with (there's a better fix for the problem with e820 reservations clashing with PCI BAR's pending), but it also actually causes more regressions, so it should be reverted even before the better fix is finalized.
