This patchset adds DT bindings and a driver for the Flash Interface Unit
(FIU), the SPI flash controller in the Nuvoton WPCM450 BMC SoC. It
supports four chip selects, and direct (memory-mapped) access to 16 MiB
per chip. Larger flash chips can be accessed by software-defined SPI
transfers.

The existing NPCM7xx FIU driver is sufficitently incompatible with the
WPCM450 FIU that I decided to write a new driver.

This patchset depends on the WPCM450 clock support patchset,

I just applied these two patches to the pinctrl tree, it looks like they
can be applied independently of the others so I just did.

So no need to resend these or include me on subsequent patch
series.

Yes, that's the intention.
