The MPC8569 Rev2.0 has the correct SNUM table as QE Reference Manual, we
must follow it.

However the Rev1.0 silicon need the old SNUM table as workaround due to
Rev1.0 silicon SNUM erratum.

So, we support both snum table, and choose the one FDT tell us.
And u-boot will fixup FDT according to SPRN_SVR.

QE_General4 should only round up the divisor iff divisor is &gt; 3.
Rounding up lower divisors makes the error too big, causing USB
on MPC832x to fail.

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.

Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

So far the driver is used to reset QE upon resume, which is needed on
85xx. Later we can move some QE initialization steps into probe().

It appears that QE shuts down on all MPC85xx CPUs (i.e. MPC8568 and
MPC8569) and thus needs reset upon resume.

So modify qe_alive_during_sleep() to account that.

For MPC8569 CPUs we'll need to reset QE after each suspend, so make
qe_reset() code path suitable for repeated invocation, that is:

- Don't initialize rheap structures if already initialized;
- Don't allocate muram for SDMA if already allocated, just reinitialize
  registers with previously allocated muram offset;
- Remove __init attributes from qe_reset() and cpm_muram_init();
