Good point !
Unfortunately I'm using the spi controller on an imx6 ("fsl,imx51-ecspi") which does not support dual or quad mode. So I cannot possibly test this :)
How would you like to proceed? Should I keep this as a private patch, and wait until someone comes along who can test this on more capable controller h/w ?
Or should I re-spin the patch without the flags?
Cheers, Sven
