when you load the module, it looks through device tree to find module-specific node

if the node is found it loads the configuration from the node

Intel is not in a position to compete with a 64-bit A64 SoC which costs $5

Подскажите?
14:43
<
premoboss >
is that the problem?
14:43
<
premoboss >
anyway thanks for trnslate
14:44
<
RandoMan70 >
Not so, the most problem is "плата"
14:44
<
RandoMan70 >
It can be "fee" or "board", depending on context
14:44
<
simosx >
The first word is for "please (v)" as in "could you please".
14:45
<
plaes >
it would make more sense with "печатная плата"
14:45
<
premoboss >
someone og you guys should to on google and use "propose a better translation" option on ggolge translator
14:46

someeone asked me if there are "externtion board" to control motors by cubieboard
14:47

that's Russian language, not cyrillic language :P

we do just that in the probe
16:01

mripard >
a1d3s: yes
16:01

but your issue is with interrupt-parent.
16:01

gpio0 doesn't exist
16:03

hmm.. it's platform_driver vs i2c_driver, but I hope I can adapt

which is the parent? 7 ?
