SubjectRe: [linux-sunxi] [PATCH] spi: dts: sun4i: Add support for inter-word wait cycles using the SPI Wait Clock Register
From
Hi Julien,

Yes, of course. What I meant was that I didn't feel comfortable to
include this magic number in driver code because I'm not 100% sure if
it is correct across all SPI configurations and SoCs that this driver
supports (A10 / A20).

I've been thinking about that, but it seemed to big a change to
attempt with my limited kernel hacking experience.

Mark, do you think we should rather talk about adding support for
options like this delay to spi-core? Or would it be OK to add it to
the sun4i driver and possibly refactor later?

Cheers,

Marcus
