2021-05-25usb: cdns3: Enable TDL_CHK only for OUT epSanket Parmar1-5/+3
ZLP gets stuck if TDL_CHK bit is set and TDL_FROM_TRB is used as TDL source for IN endpoints. To fix it, TDL_CHK is only enabled for OUT endpoints.

2021-04-12usb: cdns3: Optimize DMA request buffer allocationSanket Parmar1-6/+23
dma_alloc_coherent() might fail on the platform with a small DMA region. To avoid such failure in cdns3_prepare_aligned_request_buf(), dma_alloc_coherent() is replaced with dma_alloc_noncoherent() to allocate aligned request buffer of dynamic length.

2021-04-12usb: cdns3: Use dma_pool_* api to alloc trb poolSanket Parmar1-23/+19
Allocation of DMA coherent memory in atomic context using dma_alloc_coherent() might fail on platforms with smaller DMA region. To fix it, dma_alloc_coherent() is replaced with dma_pool API to allocate a smaller chunk of DMA coherent memory for TRB rings.
