It just works perfectly.

I don't know all the devices and users, but here is what I know: I've tested Max3110 spi-uart (in-tree), Option GTM501L high-speed 3G modem (out of tree), ektf1236 spi touch screen (out of tree). Alek Du (Cced) should have tested current dw_spi driver with some spi bluetooth device and modem device. Also the original author fordw_spi_mmio.c Jean-Hugues Deschense should have some experience too.
