Hi,
I found on my machine(lenovo T410), most of time only reading the status
register in the entry of ehci_irq may take 2~4 microseconds, and sometimes
it is extremely slow and the read can consume > 100 microseconds.
I measure the time by adding two trace events around the below line in

This moves the allocation of minor device numbers from a static array to
be dynamic, using the idr interface. This means that you could
potentially get "gaps" in a minor number range for a single USB serial
device with multiple ports, but all should still work properly.

This patch moves at91_pmc.h header from machine specific directory
