[PATCH] usb: cdns3: Coherent memory allocation optimization

2021-03-05 Thread Sanket Parmar
Allocation of DMA coherent memory in atomic context using dma_alloc_coherent() might fail on some platform. To fix it, Replaced dma_alloc_coherent() with dma_pool API to allocate a smaller chunk of DMA coherent memory for TRB rings. Also in cdns3_prepare_aligned_request_buf(), replaced dma_alloc_c
