You must have missed the patch 16:
0e8332aaf059 dt-bindings: spi: Convert DW SPI binding to DT schema
As you can see it has been acked by Rob. So you can also merge it into your
repo. Though It has to be rebased first due to the Dinh Nguyen patches
recently merged in. Do you want me to do the rebasing?
