For each transfer type, controller has a 4-bit register field to enable different cache type. Quoted from DWC3 data book Table 6-5 Cache Type Bit Assignments: ---------------------------------------------------------------- MBUS_TYPE| bit[3] |bit[2] |bit[1] |bit[0] ---------------------------------------------------------------- AHB |Cacheable |Bufferable |Privilegge |Data AXI3 |Write Allocate|Read Allocate|Cacheable |Bufferable AXI4 |Allocate Other|Allocate |Modifiable |Bufferable AXI4 |Other Allocate|Allocate |Modifiable |Bufferable Native |Same as AXI |Same as AXI |Same as AXI|Same as AXI ---------------------------------------------------------------- Note: The AHB, AXI3, AXI4, and PCIe busses use different names for certain signals, which have the same meaning: Bufferable = Posted Cacheable = Modifiable = Snoop (negation of No Snoop) In most cases, driver work well with default value. But USB device detect failure sometime on Layerscape platforms if bit[1] not set and enable dma-coherent. Set bit[1] "Snoop" for Data Read, Desc Read, Data Write and Desc write if compatible string contain fsl,ls-dwc3.
