This patch removes the cast on data of type void* as it is not needed.

Sometimes the comm field in the trace.dat file can be empty which means that the
event parsing stuff can pass a NULL into pevent_register_comm. To fix this just
check if we are NULL and generate a bogus comm name for that PID. This keeps us
from segfaulting. Thanks,

v3:
- added trace format documentation and example
- added mode detailed trace when --verbose specified
v2:
- added more info to the changelogs
- reworked options (-f -> -F, --pgfaults -> --pf=[all|min|maj])
This patch adds optional pagefault tracing support to 'perf trace'.
Using -F/--pf option user can specify whether he wants minor, major or
all pagefault events to be traced. This patch adds only live mode,

Currently, timechart records only scheduler and CPU events (task switches,

makes it's possible to record IO (disk, network) activity. In this mode
perf timechart will generate SVG with IO charts (writes, reads, tx, rx, polls).
Firefox doesn't correctly handle cases where we specify number in

Hi everyone,
This is v4 of the sun8i clock series, which adds basic clock
support for the A23 SoC. It is based on my initial sun8i bring
up series [1]. This series was split up from the original A23
series [2]. Yet to come are more clocks, reset controllers,
prcm, pinctrl, and mmc.
The first
The clock control unit on the A23 is similar to the one found on the A31.
The AHB1, APB1, APB2 gates on the A23 are almost identical to the ones
on the A31, but some outputs are missing.
The main CPU PLL (PLL1) however is like that on older Allwinner SoCs,
such as the A10 or A20, but the N

A few of the clock modules have odd dividers, such as
the 2 lowest dividers being the same (2), or have the
same divider when the highest bit is set.
This patch adds support for optional divider tables,
so the clock framework will know about the odd values.

The new important clock protect code requires the clocks be
registered with clkdev. This was missing for sunxi_gates

Now that we have support for sun8i specific clocks in the driver,
add the corresponding clock nodes to the DTSI. Also update the
existing peripherals with the correct clocks.

When writing a module for testing or debugging purposes, there is no way to
get hold of clk handles. This patch solves this by exposing all valid clocks
as clkdev's for the virtual device tegra-clk-debug.
