[PATCH 1/3] ARM: Samsung: Move timer irq numbers to end of linux irq space

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All of Samsung's s5p platforms have timer irqs statically mapped from linux
irq numbers 11 to 15. These timer irqs are moved to end of the statically
mapped linux irq space and the hardware irqs, which were statically mapped
starting from 32 is moved to start from 0. The NR_IRQS macro is consolidated
for all the s5p platforms in this process.
