isp1763 have some differences from the isp1760, 8 bit address for
registers and 16 bit for values, no bulk access to memory addresses,
16 PTD's instead of 32.
Following the regmap work done before add the registers, memory access
and add the functions to support differences in setup sequences.

There are a lot of pre-existing typechecking warnings around the
access and assign of elements of ptd structure of __dw type.
sparse: warning: invalid assignment: |=
sparse: left side has type restricted __dw
sparse: right side has type unsigned int
or
warning: restricted __dw degrades to integer
or
sparse: warning: incorrect type in assignment (different base types)
sparse: expected restricted __dw [usertype] dw4
sparse: got unsigned int [assigned] [usertype] usof
To handle this, annotate conversions along the {TO,FROM}_DW* macros
and some assignments and function arguments.
This clean up completely all sparse warnings for this driver.

On start-up, we can get a spurious session request interrupt with nothing
connected. After that the devctl session bit will silently clear, but the
musb hardware is never idled until a cable is plugged in, or the glue
layer module is reloaded.
Let's just check the session bit again in 3 seconds in peripheral mode
to catch the issue.

Looks like we are missing suspend and resume functions for pm_ops that
are needed to idle the hardware for system suspend for 2430 glue layer.
We can rely on the driver internal PM runtime state, and call driver
functions to idle the hardware on suspend if needed. There is no need
to add a dependency to PM runtime for system suspend here.

Make use of the struct_size() helper instead of an open-coded version,
in order to avoid any potential type mistakes or integer overflows
that, in the worse scenario, could lead to heap overflows.
This code was detected with the help of Coccinelle and, audited and
fixed manually.

There is no need to store the dentry for a fixed filename that we have
the string for. So just have debugfs look it up when we need it to
remove the file, no need to store it anywhere locally.
Note, this driver is broken in that debugfs will not work for more than
one instance of the device it supports. But given that this patch does
not change that, and no one has ever seemed to notice, it must not be an
issue...

"Two fixes for timers:
- Use the ALARM feature check in the alarmtimer core code insted of
the old method of checking for the set_alarm() callback.
Drivers can have that callback set but the feature bit cleared. If
such a RTC device is selected then alarms wont work.
- Use a proper define to let the preprocessor check whether Hyper-V
VDSO clocksource should be active.
The code used a constant in an enum with #ifdef, which evaluates to
always false and disabled the clocksource for VDSO"

"The three SEV commits are not really urgent material. But we figured
since getting them in now will avoid a huge amount of conflicts
between future SEV changes touching tip, the kvm and probably other
trees, sending them to you now would be best.
The idea is that the tip, kvm etc branches for 5.14 will all base
ontop of -rc2 and thus everything will be peachy. What is more, those
changes are purely mechanical and defines movement so they should be
fine to go now (famous last words).
