For example, the dts file should look something like this: spi-controller { gpios = <&pio1 1 0 /* cs0 */ 0 /* cs1, no GPIO */ &pio2 2 0>; /* cs2 */Interesting scheme. I guess this is for eSPI controllers that can do their own chip-selects, but we want GPIO chip selects in addition (or in place of built-in ones), correct?
That is a good question. What HW is this for (I don't think its for eSPI but I could be wrong).
