Already existing property flags are filled wrong for properties created from
initial FDT. This could cause problems if this DYNAMIC device-tree functions
are used later, i.e. properties are attached/detached/replaced. Simply dumping
flags from the running system show, that some initial static (not allocated via
kzmalloc()) nodes are marked as dynamic.
I putted some debug extensions to property_proc_show(..) :
..
+ if (OF_IS_DYNAMIC(pp))
+ pr_err("DEBUG: xxx : OF_IS_DYNAMIC\n");
+ if (OF_IS_DETACHED(pp))
+ pr_err("DEBUG: xxx : OF_IS_DETACHED\n");
when you operate on the nodes (e.g.: ~$ cat /proc/device-tree/*some_node*) you
will see that those flags are filled wrong, basically in most cases it will dump
a DYNAMIC or DETACHED status, which is in not true.
(BTW. this OF_IS_DETACHED is a own define for debug purposes which which just
make a test_bit(OF_DETACHED, &x->_flags)
If nodes are dynamic kernel is allowed to kfree() them. But it will crash
attempting to do so on the nodes from FDT -- they are not allocated via
kzmalloc().

"Just a single patch which fixes a special case in the MIPS FPU
emulator which is always required, even on CPUs with FPU. There is
the rare special case that an FPU (or certain other instructions) in a

instruction will need to be emulated by the kernel before resuming
execution. This is working great except if the branch instruction is
an Octeon BBIT instruction.
The boring disclaimer - all MIPS defconfigs build tested and no
regressions and runtime tested on Octeon, no known issues"

When a cpu goes to a deep idle state where its local timer is shutdown, it
notifies the time frame work to use the broadcast timer instead.
Unfortunately, the broadcast device could wake up any CPU, including an idle one
which is not concerned by the wake up at all.
This implies, in the worst case, an idle CPU will wake up to send an IPI to
another idle cpu.

Signed-off-by: Kevin Hilman <khilman@linaro.org>
cleanup the clock API use of the UART driver which is shared among the
MPC512x and the MPC5200 platforms
- get, prepare, and enable the MCLK during port allocation; disable,
unprepare and put the MCLK upon port release; hold a reference to the
clock over the period of use; check for and propagate enable errors
- fix a buffer overflow for clock names with two digit PSC index numbers
- stick with the PPC_CLOCK 'psc%d_mclk' name for clock lookup, only
switch to a fixed string later after device tree based clock lookup
will have become available
to achieve support for MPC512x which is neutral to MPC5200, the
modification was done as follows
- introduce "clock alloc" and "clock release" routines in addition to
the previous "clock enable/disable" routine in the psc_ops struct
- make the clock allocation a part of the port request (resource
allocation), and make clock release a part of the port release, such
that essential resources get allocated early
- just enable/disable the clock from within the .clock() callback
without any allocation or preparation as the former implementation
did, since this routine is called from within the startup and shutdown
callbacks
- all of the above remains a NOP for the MPC5200 platform (no callbacks
are provided on that platform)
- implementation note: the clock gets enabled upon allocation already
