This series addresses a couple of FIFO issues in dwc2. The first it properly configures the GDIFIFOCFG registers in host/gadget mode.
Next it configures the TX FIFOs to default values in gadget mode. These values should work for all cores. The old constant values were incorrect in some cases depending on the core configuration. These value may still be overridden on a per-platform basis and we add checks to make sure that overridden values are consistent with the hardware capabilities and fall-back to defaults if so. Test on Synopsys HAPS core version 3.30a. Appreciate any Tested-by's on other platforms. This series depends on the latest dwc2 patches for next and 4.10-rc5 [1] which you can find applied to my git tree for convenience [2].
