drm_mode_connector_attach_encoder() function call is missing
during eDP and DSI connector initialization. As a result,
no encoder is returned by DRM_IOCTL_MODE_GETCONNECTOR system
call. This change is to fix this issue.

Hi Arnd,
Thanks for the initial feedback. I'll investigate your suggestions and
get back to you if I have any questions before making some of the API

This is the port of the hardware latency detector from the -rt patch
to mainline. Instead of keeping it as a device that had its own debugfs
filesystem infrastructure, it made more sense to make it into a tracer
like irqsoff and wakeup latency tracers currently are.
With this patch set, a new tra

Instead of just running a single kernel thread to do the hardware latency
detection, run one on each CPU that the user specificies. By default
this will be just one CPU (on CPU 0). But the user may specify what
CPUs they would like to run the tests on.

Hey Punnaiah-
A few nitpicks here, in case you'll be spinning up a new version of your
patchset.

Hello!
This series is strictly FYI.
I am simply sending it as a heads-up. The diagnostics surrounding using
RCU from an offline CPU will be tightening up, which might cause splats
to come my way. If such splats do come my way, I will reply with the
patches in this series.
I know you guys have

Be consistent, use cros_ec instead of "cros ec" or "cros-ec".

In NX we need to pass always a 16 multiple size nx_sg_list to
co processor. Trim function handle with this assuring all nx_sg_lists
are 16 multiple size, although data was not being considerated when
crop was done. It was causing an unalignment between size of the list
and data, corrupting csbcpb f

Bug happens when a data size less than SHA block size is passed.
Since first attempt will be saved in buffer, second round attempt
get into two step to calculate op.inlen and op.outlen. The issue
resides in this step. A wrong value of op.inlen and outlen was being
calculated.
This patch fix this
