Hi Sebastian,

This patch renames the type struct from ti81xx_driver_data to
am33xx_driver_data since it is not used for ti81xx anymore. The EOI
member is also removed since the am33xx SoC does not have such register.
The interrupt is acknowledged by writting into the stat register.
AM335X TRM Section 16.6.5 and 16.7.5 describes about EOI registers.
Its at offset 0x24. Or is it that the interrupts are acknowledged even
without writing to eoi register?
I have here "Literature Number: SPRUH73H October 2011 Revised April
2013" which calls itself "AM335x ARM® CortexTM-A8 Microprocessors
(MPUs) Technical Reference Manual".
Looks like I have an old TRM with me, which has EOI register at 24h.
I need to update my TRM. ;)
This document ends with 16.5 that means there is no chapter 16.6 or
16.7. The next one is 17.
16.5.2 and 16.5.3 describes the available registers of
USB[01]_CTRL REGISTERS which is where the EOI register is accessed. I
see here
20h USB0IRQMSTAT
28h USB0IRQSTATRAW0
so no 0x24 at least in my document.
