usb: dwc3: omap: Adding am437x specific register map changes
AM437x and OMAP5 dwc3 subsytem have different register map.
Major differences are as follows.
OMAP5 has one main interrupt and one misc interrupt
Aegis has four main interrupts and one misc interrupt.
Miscellanous Interrupt offsets are changed.
UTMI OTG Control and Status Registers offsets are changed.
DEBUG Configuration and Status Registers are changed.
The main intend of the patch is to re-use the same wrapper driver
for both OMAP5 and AM437x, by using the x_major in revision
register and adjusting the offsets.
This patch adds the register map offsets and adds offset variables
in struct dwc3_omap to cache the offsets

do_smart_update_queue() is called when an operation (semop,

which of the sleeping tasks can proceed.
do_smart_update_queue() missed a few wakeups:
- if a sleeping complex op was completed, then all per-semaphore queues
must be scanned - not only those that were modified by *sops
- if a sleeping simple op proceeded, then the global queue must be
scanned again
And:
- the test for "|sops == NULL) before scanning the global queue is not
required: If the global queue is empty, then it doesn't need to be
scanned - regardless of the reason for calling do_smart_update_queue()
The patch is not optimized, i.e. even completing a wait-for-zero
operation causes a rescan. This is done to keep the patch as simple as

reentrant which fixed some strange kernel crashes (specifically
protection ID traps).
Furthemore this patchset fixes the interrupt stack in UP and SMP

usage of floating point calculations on parisc were disabled in the
MPILIB."
