The poodle restart handler was added in 74617fb6 (3593/1: Add reboot and shutdown handlers for Zaurus handhelds), and at that time it was necessary to deal with the RCSR register. This commit also forced all restarts to use the 'hard' restart method. In dc38e2ad (pxa: Fix RCSR handling), the RCSR handling was removed, leaving just the forcing to use a 'hard' restart. As hard restarts are the default (in the absense of a reboot= command line argument), this seems pointless. In any case, Richard Purdie says: > From what I remember that hardware either always reboots or always > halts. I think the option was therefore left hardcoded to make it clear > it wasn't expected to work. Later Zaurii models could do either but > required some manual poking of registers to make it happen iirc. > > Regardless, you can probably clean this up as you suggest now. So, lets remove the unnecessary interception and rely on the default restart mode. Acked-by:

We only need to set the system up for a soft-restart if we're going to be doing a soft-restart. Provide a new function (soft_restart()) which does the setup and final call for this, and make platforms use it. Eliminate the call to setup_restart() from the default handler. This means that platforms arch_reset() function is no longer called with the page tables prepared for a soft-restart, and caches will still be enabled. Acked-by:

As suggested by Russell King - ARM Linux <linux@arm.linux.org.uk>, there's no need to keep local prototypes in non-local headers. Add mach-omap1/common.h and mach-omap2/common.h and move the local prototypes there from plat/common.h and mach/omap4-common.h. Signed-off-by:

Add a handler for the VIC that is suitable for MULTI_IRQ_HANDLER platforms. This can replace the ASM entry macros for platforms that use the VIC. v4: - rebase ontop of move __exception and friends to asm/exception.h - rework polling loop to handle as many irqs as possible in one go v3: - simplify irq handling loop as suggested by Grant - service interrupts from msb->lsb order v2: - allow the handler be used for !CONFIG_OF - use irq_domain_to_irq() Cc: Rob Herring <robherring2@gmail.com> Acked-by:

This adds a device tree binding for the VIC based on the of_irq_init() support. This adds an irqdomain to the vic and always registers all vics in the static vic array rather than for pm only to keep track of the irq domain. struct irq_data::hwirq is used where appropriate rather than runtime masking. v3: - include linux/export.h for THIS_MODULE v2: - use irq_domain_simple_ops - remove stub implementation of vic_of_init for !CONFIG_OF - Make VIC select IRQ_DOMAIN Reviewed-by:
