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 !
