2012-02-27ARM: OMAP: make iommu subsys_initcall to fix builtin omap3ispOhad Ben-Cohen
omap3isp depends on omap's iommu and will fail to probe if initialized before it (which always happen if they are builtin). Make omap's iommu subsys_initcall as an interim solution until the probe deferral mechanism is merged.

2012-02-23ARM: OMAP2: fix mailbox init codeOhad Ben-Cohen
Fix this: arch/arm/mach-omap2/mailbox.c: In function 'omap2_mbox_probe': arch/arm/mach-omap2/mailbox.c:354: error: 'omap2_mboxes' undeclared (first use in this function) arch/arm/mach-omap2/mailbox.c:354: error: (Each undeclared identifier is reported only once arch/arm/mach-omap2/mailbox.c:354: error: for each function it appears in.) Which happens on CONFIG_ARCH_OMAP2 && !CONFIG_SOC_OMAP2420, due to missing omap2_mboxes declaration. In addition, make sure we declare the right mailbox instances for 2430.

2009-09-24omap: mailbox: Flush posted write when acking mailbox irqHiroshi DOYU
The only way to flush posted write to L4 bus is to do a read back of the same register right after the write. This seems to be mostly needed in interrupt handlers to avoid causing spurious interrupts. The earlier fix has been to mark the L4 bus as strongly ordered memory, which solves the problem, but causes performance penalties.
