Keep it consistent - either descriptions are the last property or
somewhere else. Usually the last.

And what does it mean? What happens if BT uses antenna number 2,
not 1?
What is connected to the other antenna? It really feels useless
to say
which antenna is connected to hardware.
Sorry, the antenna description was incorrect, it should specify
whether
Bluetooth and WiFi coexist. I will change it as below:
aml,work-mode:
type: boolean
description: specifywhether Bluetooth and WiFi coexist.
So one device can be used on different boards - some without WiFi
antenna? But, why in the binding of bluetooth you describe whether
there
is WiFi antenna?
Yes, it can be used on dirfferent boards. The device can operate in
both
Please do not respond to only partial part of the comment. It is obvious
device can work on different boards. You do not have to confirm it. The
question was different - why do you need this property? I gave you
possible answer, but you skipped this and answered with obvious
statement.
I'm sorry. I didn't explain it clearly.
Board design should be optimized for specific use cases: use the
standalone mode for high-speed, stable, and Bluetooth-only
applications; opt for the coexistence mode in cost-sensitive scenarios
with lower performance demands. Once the hardware is determined, the
user needs to configure the working mode of the firmware.
standalone mode and coexistence mode. typically running standalone
mode.
Therefore, I would like to revise the description as follows:
aml,coexisting:
type: boolean
description: Enable coexistence mode, allowing shared antenna
usage
with Wi-Fi.
Why this is not enabled always?
The board design determines whether to enable this property.
Well, I know I should clearly describe why this property is enabled
here, so I modify it as follows:
aml,coexisting:
type: boolean
description: Enable co-existence mode on boards sharing antennas
with Wi-Fi.
Hi Krzysztof
After internal discussions, we determined that Bluetooth Controllers
typically operate in standalone mode and are only configured for sharing
upon customer-specific customization. Consequently, we have decided to
remove this property. Please be advised that the third patch will be
updated accordingly at a later date
Best regards,
Krzysztof
