* Blackfin arch: reset POLAR setting when acquiring a gpio for the first timeMichael Hennerich2009-02-041-1/+7
| | | | | | | | | | | | | | | | | | | | | when requesting a GPIO for the first time, the POLAR setting is not set to a sane state. this can lead to indeterminate behavior that cannot be resolved without an explicit write to the Blackfin port POLAR register. when requesting a GPIO for the first time via gpio_request(), the POLAR setting for the GPIO in question should be set to sane state. this should occur if the GPIO has not been allocated in any other way. some examples: - when doing something like "request_irq(); gpio_request();" on the same GPIO, the POLAR setting should not be reset. - when doing "gpio_request(); gpio_request();" on the same GPIO, the POLAR setting should be reset only the first time and not the second.

| | * ARM: OMAP: Mask interrupts when disabling interrupts, v2김규원2009-01-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By Ingo Molnar, interrupts are not masked by default. (refer to 76d2160147f43f982dfe881404cfde9fd0a9da21) But if interrupts are not masked, the processor can wake up while in Suspend-to-RAM state by an external interrupt. For example, if an OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM state, it wake up automatically by M_IRQ_92. The disable_irq() function can't disable the interrupt in H/W level, So I modified arch/arm/mach-omap2/irq.c Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

A write to the timer device will be usually posted, but it takes roughly 3 cycles before it is effective. If the timer is reprogrammed before that, the CPU will stall until the previous write completes. This was pointed out by Richard Woodruff. Since the lower bound for min_delta_ns is 1000, the change is visible only with tick rates less than 3 MHz. Also note that the old value is incorrect for 32 kHz also due to a rounding error, and it can cause the timer queue to hang (due to clockevent code trying to program the timer with zero ticks).

The solution is to remove the virtual clock and enable these child clocks in omap_mcbsp_request() directly.

| * | [ARM] 5366/1: fix shared memory coherency with VIVT L1 + L2 cachesNicolas Pitre2009-01-281-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there are multiple L1-aliasing userland mappings of the same physical page, we currently remap each of them uncached, to prevent VIVT cache aliasing issues. (E.g. writes to one of the mappings not being immediately visible via another mapping.) However, when we do this remapping, there could still be stale data in the L2 cache, and an uncached mapping might bypass L2 and go straight to RAM. This would cause reads from such mappings to see old data (until the dirty L2 line is eventually evicted.) This issue is solved by forcing a L2 cache flush whenever the shared page is made L1 uncacheable. Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding for XSc3 doesn't appear to work in practice.

Without this patch, the memory window BAR is left at whatever value happened to be loaded into the BAR when Linux was booted. Without this patch, memory could end up getting mapped at any of the 1G address boundaries instead of at '0' where Linux expects it. Similarly, this patch also ensures that the internally memory mapped registers (IMMR) are mapped to the correct PCI address range. Without this patch, PCI appears to work correctly until a PCI device is inserted which DMAs into memory.
