As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
