Hi,
I have a custom board which has two LMH0303 SDI drivers on the same
i2c bus. They are connected in some daisy chain form, like on the
schematics in the datasheet on page 9 :
http://www.ti.com/lit/ds/symlink/lmh0303.pdf
My problem is how to declare these devices in the DT in order to set
the new adress of the first one when probed.
I thought that something like that could do the trick but it seems crappy :
lmh0303@17 {
new-addr = <0x16>;
rsti_n = <&gpio1_17>; /* GPIO signal connected to the RSTI signal
of the first LMH0303 */
};
lmh0303@17 {
/* Nothing to do right now */
};
This is a draft thought :).
Maybe would it also be possible do define a "super device" like this :
lmh0303@17 {
lmh0303_1 {
new-addr = <0x16>;
rsti_n = <&gpio1_17>; /* GPIO signal connected to the RSTI
signal of the first LMH0303 */
};
lmh0303_2 {
};
};
This would be something like the gpio-leds binding...
But there is probably already a nice way to do that :-) ?
Thanks for your advices !
JM
