The Microchip MPFS Icicle Kit uses Cadence SD/SDIO/eMMC Host Controller without any additional vendor compatible:I think the lack of vendor compatible is the error here. Experience has shown that vendor specific compatibles are needed for licensed IP.In such case this could be: 1. a specific "microchip,mpfs250t-sd4hc", which seems to be on MPFS Icicle Kit: https://www.digikey.co.uk/en/product-highlight/m/microchip-technology/mpfs-icicle-kit-es--polarfire-soc-fpga-icicle-kit 2. or a generic "microchip,mpfs-sd4hc" Any hints here?Best for a Microchip person to answer, but sure there's some existing compatible strings for other blocks on this chip to follow the same pattern.

#2 would be ideal since the controller doesn't change across the part range, the 250t bit in the part name just covers the size/configuration of the FPGA. Conor
