Add initial clock support for Marvell PXA1928. The PXA1928 is a mobile
SOC and is similar to other MMP/PXA series of SOCs, so a lot of the
existing infrastructure is reused here.
Currently the PLLs are just fixed clocks, and not all leaf clocks are
implemented.

c56fb6564dcd ("Fix a misaligned load inside ptrace_attach()") makes
jobctl an "unsigned long". It makes sense to have the masks applied
to it match that type. This is currently just a cosmetic change, but
it will prevent the mask from being unexpectedly truncated if we ever

The misaligned load exception arises when running ptrace_attach() on
the RISC-V (which hasn't been upstreamed yet). The problem is that
wait_on_bit() takes a void* but then proceeds to call test_bit(),

We change the one header file wich gives us coverage on both files:
The files changed here are simply modular source files that are implicitly
relying on being present. We fix them up now, so that we can

Andy pointed out to me something I should have seen earlier: both
syscall_trace_leave and do_notify_resume call both user_exit()
and user_enter(), which has the potential to greatly increase the
cost of context tracking.

Currently, we assume a device_type of BTN_TOOL_PEN before scanning the
HID descriptor and then change the device_type if what we discover
proves that assumption wrong. This way of doing things makes it more
difficult to figure out if a device (particularly a HID_GENERIC device)
actually does
The last patch was careful to maintain backwards-compatible behavior
by forcing device_type to BTN_TOOL_PEN (and printing a warning) if it

quirks. We should be more strict with HID_GENERIC devices, however,
since there is no a

This condition can't ever be true because this function is static
and it's always called with a non-NULL pointer.

The debugfs clk directory no longer expresses a clk tree. Update
the comments around that apporiately. Also drop comments about
prepare locks needing to be held as we have the proper
annotations with lockdep_assert_held().

Move the code around so that we don't need to declare function
prototypes at the start of the file. Simplify
clk_core_is_prepared() and clk_core_is_enabled() too to make the
diff easier to read.

While introducing struct clk_core we tried to minimize the diff
by changing the type of 'clk' variables from struct clk to struct
clk_core without changing the names of the variables. Now that
the split is complete, the code is slightly confusing when it
mixes variables called 'clk' and variables
Here are some cleanups spurned by some patches from Dong Aisheng.
No functionality is changed, just reordering of code, etc.

These functions are only used in one place. Let's squash them

We don't need to print error messages when allocations fail.
We'll get a nice backtrace in such situations anyway.

wait_event_interruptible_timeout() returns 0 upon timeout. We should
convert it to a negative error code (such as -ETIMEDOUT) instead of
returning it directly, as return code of 0 indicates that command was
executed.
