Dear Friend,
Good day. I am Mr. Mudi Feez. I am working with one of the prime banks
in Burkina Faso. I have decided to contact you for a financial
transaction which values $14,500,000.00 (Fourteen Million Five Hundred
Thousand USA Dollars). This is an abandoned fund that belongs to a
late foreign customer of our bank. I want a foreign account where the
bank will transfer this fund.
I was very fortunate to come across the deceased customer's security
file; during documentation of old and abandoned customers files for an
official re-documentation and audit of the year 2017.
If you are really sure of your trustworthiness, accountability and
confidentiality over this transaction, contact me urgently. I will let
you know the next step and procedure to follow in order to finalize
this transaction successfully.
I expect your urgent communication.
Yours sincerely,
Mr. Mudi Feez

Would certainly work, especially since we have been doing this for
other properties. Is there an obvious pro to doing this though?

* [PATCH v2] ARM: dts: armada-38x: label USB and SATA nodes
From: Ralph Sennhauser @ 2017-04-08 10:16 UTC (permalink / raw)

Recently most nodes got labels to make them referenceable. The USB 3.0
nodes as well as the nodes for the SATA controllers were left out,
rectify the omission.
The labels "sataX" are already used by some boards for the SATA ports,
therefore use "ahciX" to label the SATA controller nodes.
To avoid potential confusion by labeling an USB3.0 controller "usb2" use
usb3_X as labels. This also coincides with the node names themselves
(usb@xxxxx vs usb3@xxxxx).
Signed-off-by: Ralph Sennhauser <ralph.sennhauser-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Hi everybody,
Using satacX for controllers with satacXpY for ports might have been a
possiblity, since ahciX is already used similarly (to avoid a conflict
with current use of sataX) ahciX seems the better choice. Works well me
thinks.
The usb3_X labels still seem the best choice even though they aren't
perfectly consitent, however, I don't see an alternative which would fit
this requirement either.
Regards
Ralph

Changes v1 -> v2:
* use ahciX instead of satacX for the SATA controller nodes (suggested

Ok, that's "really interesting" one. As far as I can see, the pattern
really should only contain justtwo intensities...

That's why I believe it is important to present whole pattern engine
as one unit to the userspace. Userspace should always upload pattern
for _all_ the LEDs at once.

Up to you, I guess. Both rejecting and best-effort make some sense.
OTOH if pattern is "(off, 0msec), (white, +1000msec), (off,
+0msec)"... you can't really do it "exactly" even on LP5xx, due to
non-trivial conversion between PWM and what user sees....
So on LPG you'd really do "(off, 0msec), (10% white, +100msec), (20%
white, +100msec), ..."
AS3676... I guess after we reject all patterns that have more than 0
and one specific brightness, we can use similar approximation we'd do
on LPG?

Well, compensation needs to happen "during the transitions",
too.

Yes... that's easy, but I believe too limiting. Users will want to
configure their own patterns for their own events.

Yes, I have something like that, too.

That was my first intention to release the reset line in case somebody else wants to control it. I did it
like that because usually reset line controls multiple devices and probably some upper layer wants to
control that.
After your comment I did some analysing and I will follow your advice and change the reset line handling.
Once the GPIO is provided to the driver the driver will own it and bring out the device from reset. In case not
provided the reset line is somebody else responsibility.
This way we are able to cover multiple use-cases.

to the hisilicon arm64
dt tree since this series patches just to add the nodes and the binding
has been reviewed before.

Hi,
First of all thank you Rob for your time and patience. Especially on how this patch was sent out. I would ensure it would not happen again for the subsequent patches.
On the issue of why the DT has certain resolution fixed is due to the fact that our Quartus system generates these attributes in according to the specific display resolution as desired by the user. The values here are the ideal resolution supported by the hardware for the reference design.
On the other hand my bad on the vendor prefix as I misunderstood the "altr," as the vendor prefix
Thanks
Hean Loong
