I'm afraid this will actually break SPI NORs for example where CS actually splits transactions.

Isn't Amjad change enough ? The CLK pull-up should avoid this.

It looks like it is not enough unfortunately.

If it's not the case, then it's an HW issue and the CLK line pull-up is too weak and an external pull should then be added.

Alright, I'll drop this patch in the next respin if needed.

Thanks,
