Things like gnss uses the current-speed attribute to set a serial link speed,
maybe also Bluetooth?
As far as I can tell, not many Bluetooth drivers use the current-speed
attribute yet but perhaps it would be a good idea to start using it more
broadly in the future to set the initial serial link speed.
Would it make sense to use
current-speed-auto;
As a flag for these things in general?
I suppose a general flag could be useful but to be honest I don't know
if any other devices besides the ones using the Broadcom driver has any
use for it. You would probably also still want to be able to use
current-speed to set the link speed and end up using both
current-speed=x and current-speed-auto at the same time, which might
look a little confusing?
Please let me know if you'd still prefer "current-speed-auto" over
"brcm,uses-autobaud-mode" and I'll revise the patch and rename it!
Yours,
Linus Walleij
Thanks,
Håkan
