Hi Marcel,
Please let us know if this patch will be acceptable or suggestions for
changes to make it so.
Thanks,
Matt Wilson
Any comments for this patch?
Sorry to send only CC: to the list before.
I assume that error makes a review difficult.
I have an update for this patch for setting baud rate and do not know if
I should update the original or make a new separate patch.
Please also find the original ones (download patch and firmware patch)
here:
https://www.codeaurora.org/patches/quic/chrome/0001-Firmware-download-for-Qualcomm-Bluetooth-devices.patch
https://www.codeaurora.org/patches/quic/chrome/0001-Firmware-for-Qualcomm-Bluetooth-BTS4025.patch
These are from the Code Aurora Forum partner Qualcomm Innovation Center,
Inc.
Best regards,
Matt Wilson

Thanks. The patch is now pushed upstream with a few more cosmetic
(coding style) changes. Take a look at the upstream tree if you're
interested in the details.

Configures device address from hciattach parameter.
UART speed limited to 115200.
Requires separate device specific firmware.

The style is from prior commit a8de99bdd963f0980877e066c7802c4247c1000c
but I will fix anyway (just in this file; not in hciattach_tialt.c)

Thanks, the patch applies cleanly now. However, I spotted a couple of

This one looks like it goes beyond 80 columns. Please split it. Also,
the coding style is to put the opening brace of a function on its own

Configures device address from hciattach parameter.
UART speed limited to 115200.
Requires separate device specific firmware.

Sorry about forgetting about this one. Unfortunately it doesn't apply
anymore to bluez.git due to the ath3k patches that got merged earlier

the patch seems fine to me.

I am actually fine with this. Except strip it from claiming copyright on
hciattach.c and hciattach.h since these changes are not really anything
new. They are just wrapping code.
So fix this and submit a new clean patch.

Marcel:
Here's the a ping regarding the patch submitted by Matt back in March? I
believe. For you convenience I've included the patch again. Please take
a look, and provide your general comments. I'm sure there are changes
that need to be made.
Fyi. sorry about the column wrap in the patch. Don't feel like fixing it
for just a quick review.
