The dra7xx-evm box freezes hard at the very first PCI bus access, the
call to in dra7xx_pcie_readl() in dra7xx_pcie_probe().

The out-of-tree 3.14.53 TI driver performs a reset via platform data,
calling omap_device_assert_hardreset() by hook and crook.

Yeah, this is the only feasible way and not break multi-arch atm until a
reset framework is in place. We have couple of drivers (omap_iommu and
wkup_m3_rproc) following this approach.

Sounds like doing reset with platform data is the way to go until the
reset controller works.

All right. I'll post the patch to do reset using platform data.

Thanks
