Can't you just deduce an unused HW CS from the cs-gpios property?
Thanks for a review. Yes, I probably can. I just noticed that my local use
of spi-orion's "direct mode" is probably the root cause of some weirdness
that I'm seeing (such as the CS GPIO pin going up in the middle of a
two-byte transaction, and other nasty issues that just go away once one
adds a dev_info call...).
Renesas MSIOF also requires driving a native chip select, cfr. commit
b8761434bdec32fa ("spi: sh-msiof: Implement cs-gpios configuration").
I'll take a look. It could be a candidate for some shared code, I suppose.
Cheers,
Jan
