The code selecting a device for the sdhci host has been continuously tweaked (4b711cb13843f5082e82970dd1e8031383134a65 "mmc: sdhci-pltfm: Add structure for host-specific data" and a4d2177f00a5252d825236c5124bc1e9918bdb41 "mmc: sdhci-pltfm: dt device does not pass parent to sdhci_alloc_host" while there does not seem to be any reason to use platform device's parent in the first place. The comment saying "Some PCI-based MFD need the parent here" seem to refer to Timberdale FPGA driver (the only MFD driver registering SDHCI cell, drivers/mfd/timberdale.c) but again, the only situation when parent device matter is runtime PM, which is not implemented for Timberdale.

Thanks! Queued for 3.18. Kind regards Uffe
