Re: [PATCH v12] ath10k: add LED and GPIO controlling support for various chipsets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




taken a look at the specific code, and from my point of view the code
that sets up the LED (including callback) is so trivial that it's simply
not worth dealing with adding the leds-gpio driver to the mix.
It adds extra complexity and an extra dependency for no reason at all.
There's no extra functionality to be gained by using it.
Stupid question: If the LED driver isn't using the GPIO subsystem
(when enabled), what happens if the user uses the GPIO subsystem to
fiddle with the pin the LED is connected to?

in our case here it can coexist and will not have a negative effect since the led will still run. (except if you reconfigure the gpio to input)
for sure it makes no sense.
but however i can block the gpio for beeing reused if the led driver took it. this has been made in ath9k for instance.
in ath10k i did not do it, since there is no technical requirement for it.
but that might not be the case for all gpio controllers, so there is no generic answer. for ath10k. harmless
