Typo it must be
cs2@68000010 {
[...]
}
As the chipselect registers start @0x68000000 maybe
I should add in ranges a "x 0 0x68000000 0x00080000" line? But
which value has x, as this range has no chipselect? So I could add
subnodes "cs2@680000yy" with a reg entry "reg = <x yy 4>;" with
yy = offset from 0x68000000 and drop the "cs" property?
Or are the "ti,davinci-cs" nodes no subnodes from "ti,davinci-emifa",
so I easy can use "reg = <0x68000010 4>;"?
bye,
Heiko
