Hi Sean
The dw spi devices on the Kendryte K210 must be operated in a specific fasion which cannot be achived through multiple writes to via dw_spi_xfer (as it is currently written). This patch adds an implementation of exec_op, which gives correct behaviour when reading/writing spi flash.
I would like to be able to modify the existing dw_spi_xfer function such that it works properly (e.g. with the mmc_spi driver). However, the only example code I have to work off is Kendryte's sdk (which is written in the exec_op style), and I do not have access to the datasheet (if anyone does, I would love to have a look!).

Patch 6 and 7 shall be applied via spi tree. You mix them together, the patchwork will become complicated. It will be better for me to wait for a period of time to get the approval(Reviewed-by or Acked-by) of SPI MAINTAINER.
Thanks Rick
So is this just waiting for approval, or is there a change I should make on my end?
