In am33xx and am43xx, ehrpwm tbclk is derived from functional clock of
PWMSS. The schematics and TRMs show that there is only one input clock to
the PWMSS. But currently, tbclk is wrongly shown to be deriving from
dpll_per_m2_ck instead of functional clock l4ls_gclk in the DT.
Fixing ehrpwm tbclk
ehrpwm tbclk is wrongly modelled as deriving from dpll_per_m2_ck.
The TRM says tbclk is derived from SYSCLKOUT. SYSCLKOUT nothing but the
functional clock of pwmss (l4ls_gclk).
Fix this by changing source of ehrpwmx_tbclk to l4ls_gclk.

Hi Azael,
I was finally getting around to these when you resent them. Apologies for the

Some Toshiba laptops do not come with the ECO led installed, however,
the driver is registering support for it when it should not.
This patch makes the toshiba_eco_mode_available function more robust
in detecting ECO led capabilities, not registering the led on laptops
that do not support it and r
Hi Steven,
This patch set is for linux-trace/for-next
It adds ability to attach eBPF programs to tracepoints, syscalls and kprobes.
Obviously too late for 3.20, but please review. I'll rebase and repost when
merge window closes.
Main difference in V3 is different attaching mechanism:

this example has two probes in one C file that attach to different tracepoints
and use two different maps.
1st probe is the similar to dropmon.c. It attaches to kfree_skb tracepoint and

2nd probe attaches to syscalls/sys_enter_write and computes
tracex1_kern.c - C program which will be compiled into eBPF
to filter netif_receive_skb events on skb->dev->name == "lo"
The programs returns 1 to store an event into ring_buffer
and returns 0 - to discard an event.
tracex1_user.c - corresponding user space component that:
- loads bpf program via
eBPF C program attaches to block_rq_issue/block_rq_complete events to calculate
IO latency. Then it waits for the first 100 events to compute average latency
and uses range [0 .. ave_lat * 2] to record histogram of events in this latency
range.
User space reads this histogram map every 2 seconds an

Such programs are allowed to call the same helper functions
as tracing filters, but bpf_context is different:
For tracing filters bpf_context is 6 arguments of tracepoints or syscalls
For kprobe filters bpf_context == pt_regs

the logic of the example is similar to tracex2, but syscall 'write' statistics
is capturead from kprobe placed at sys_write function instead of through
syscall instrumentation.
Also tracex4_kern.c has a different way of doing log2 in C.
Note, unlike tracepoint and syscall programs, kprobe programs
simple packet drop monitor:

of packet drops at given location
- userspace iterates over the map every second and prints stats
Usage:

Recent Toshiba laptops that come with the new keyboard layout have
the Special Functions (hotkeys) enabled by default, which, in order to
access the F{1-12} keys, you need to press the FN-F{1-12} key to
access such key.
This patch adds support to toggle the Keyboard Functions operation

Toshiba laptops come with a feature called "Panel Open - Power ON",
which makes the laptop turn on whenever the LID is opened.
This patch adds support for such feature, by creating a sysfs entry
named "panel_power_on", accepting only two values, 0 to disable and
1 to enable such feature.

Several new features were added on previous patches, so lets bump up
the driver version.
And also, update the copyright year.

These patches add five new files to sysfs.
With the first two files we are paving the way to the (hopefully)
future removal of the (now deprecated) proc entries. The remaining
entries were not ported due to the fact that they duplicate existing
kernel functionality (eg.: lcd <-> backlight, keys <-
This patch adds a new entry to the sysfs, showing the version of the
