Re: One-for-all overlay file for each sensor

Hi Aaron,

I have similar needs for networking overlay config files which are
typically the same. I created enhancement req in
https://github.com/zephyrproject-rtos/zephyr/issues/14740 for tracking
this. Please comment there if needed.


Cheers,
Jukka

Hi,

For evaluating sensor samples, I need to add overlay file for every
board into every sample. But the content of the overlay file is
almost the same, for example :
'''
&i2c0 {
hts221@5f {
compatible = "st,hts221";
reg = <0x5f>;
label = "HTS221";
};
};
'''
Only different is the overlay file's name, and need to adapt i2c
interface for different boards sometimes. After that we can fetch
data in polling mode at least.

As most of those sensors support i2c interface or SPI or both, I
think we can simplify this process with the standard interface name,
like arduino_i2c/arduino_spi. And save user's time for creating such
kind of overlay files.

Can I have a one-for-all overlay file for each sensor, which I don't
need to specify the board's name?
