2009-04-23ARM: OMAP3: Fixed spurious IRQ issue for GPIO interruptsRoger Quadros
Flush posted write to IRQSTATUS register in GPIO IRQ handler. This eliminates the below error for all peripherals that use GPIO interrupts. <4>Spurious irq 95: 0xffffffdf, please flush posted write for irq 31 Signed-off-by: Roger Quadros <ext-roger.quadros@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-04-23ARM: OMAP2/3: GPIO: do not attempt to wake-enableKevin Hilman
The GPIO IRQ enable/disable path attempts to also enable IRQ wake support for the parent GPIO bank IRQ as well. However, since there is no 'set_wake' hook for the bank IRQs, these calls will always fail. Also, since the enable will fail on the suspend path, the disable on the resume path will trigger unbalanced enable/disable warnings. This was discovered in the suspend/resume path on OMAP3/Beagle using the gpio-keys driver which disables/re-enables GPIO IRQ wakeups in the suspend/resume path.

2009-04-23ARM: OMAP2: possible division by 0Roel Kluin
In linus' git tree the functions can be found at: vi arch/arm/mach-omap2/usb-tusb6010.c +200 - tusb6010_platform_retime() vi arch/arm/mach-omap2/gpmc.c +94 - gpmc_get_fclk_period() vi arch/arm/mach-omap2/usb-tusb6010.c +53 - tusb_set_async_mode() vi arch/arm/mach-omap2/usb-tusb6010.c +111 - tusb_set_sync_mode() is -ENODEV appropriate when sysclk_ps == 0? This was found by code analysis, please review. ------------------------------>8-------------8<--------------------------------- gpmc_get_fclk_period() may return 0 when gpmc_l3_clk is not enabled. This is not checked in tusb6010_platform_retime() nor in tusb_set_async_mode() it seems. In tusb_set_sync_mode() this may result in a division by zero.

2009-04-23ARM: OMAP: Fix for possible race condition in omap_free_dma()Santosh Shilimkar
Fix the possible race condition in omap_free_dma(). Function omap_free_dma() sets the dev_id = -1 and then accesses the channel afterwards to clear it. But setting the dev_id=-1 makes the channel available for allocation again. So it is possible someone else can grab it and results are unpredictable. To avod this DMA channle is cleared first and then the dev_id = -1 is set. Thanks to McNeil, Sean <sean.mcneil@ti.com> for ointing out this issue.

2009-04-16[ARM] 5455/1: Fix IRQ noise from VIC codeLinus Walleij
The VIC code will attempt to perform som default set_irq_chip() and set_irq_chip_data() on all IRQs supported by the VIC, while the new IRQ handling code strictly checks for the global NR_IRQS to be respected also for these IRQs. This patch will respect the interrupt mask passed to the VIC driver and will prevent it from attempting to call these functions on any unused interrupts.
