This patch splits rk3399-rockpro64 dts file to 2 files for v2 and
v2.1 boards.

Both v2 and v2.1 boards can use almost same settings but we find a
difference in I2C address of audio CODEC ES8136.

The min/max value of vdd_log is decide by pwm IO voltage and its
resistors, the rk3399-firefly board's pwm regulator circuit is designed
for IO voltage at 1.8V, while the board actually use 3.0V for IO, which
at last lead to the min-microvolt to '430mV' instead of '800mV'.

Working with rootfs on two 128GB mmcs on rk3399-roc-pc.

One (mmc name 128G72, one screw hole) works fine in HS400 mode.
Other (mmc name DJNB4R, firefly on pcb, two screw holes) gets lots of

when running under heavy load, e.g. compiling kernel.
Both run fine with HS200.

It looks like the px30 is running unstable at this 408MHz operating point.
This shows in stalled threads and other big numbers of kernel exception.

At 600MHz and above it instead works stable and as expected. As the 408MHz
point doesn't even decrease the voltage compared to 600MHz, just drop this
408MHz operating point for now.

Expand the power tree description with the 0V9 and 1V8 supplies to the
RK3399 PCIe block. The NanoPis M4 and NEO4 just route 2 lanes to the

for them; NanoPC-T4 has a standard M.2 connector so we can at least
claim the 3.3V supply to that too.

Although it appeared to follow logically from the bindings, apparently
the thermal framework can't properly cope with a single cooling device
being shared between multiple maps. The CPU zone is probably easier to
overheat, so remove the references to the (optional) fan from the GPU
cooling zone to avoid things getting confused. Hopefully GPU-intensive
tasks will leak enough heat across to the CPU zone to still hit the
fan trips before reaching critical GPU temperatures.

Pull orangefs update from Mike Marshall:
 "orangefs: posix open permission checking...

  Orangefs has no open, and orangefs checks file permissions on each
  file access. Posix requires that file permissions be checked on open
  and nowhere else. Orangefs-through-the-kernel needs to seem posix
  compliant.

  The VFS opens files, even if the filesystem provides no method. We can
  see if a file was successfully opened for read and or for write by
  looking at file->f_mode.

  When writes are flowing from the page cache, file is no longer
  available. We can trust the VFS to have checked file->f_mode before
  writing to the page cache.

  The mode of a file might change between when it is opened and IO
  commences, or it might be created with an arbitrary mode.

  We'll make sure we don't hit EACCES during the IO stage by using
  UID 0"

[ This is "posixish", but not a great solution in the long run, since a
  proper secure network server shouldn't really trust the client like this.
  But proper and secure POSIX behavior requires an open method and a
  resulting cookie for IO of some kind, or similar.    - Linus ]
