dmaengine: drivers: Use devm_platform_ioremap_resource()

2023-01-18T16:46:47Z

platform_get_resource() and devm_ioremap_resource() are wrapped up in the devm_platform_ioremap_resource() helper. Use the helper and get rid of the local variable for struct resource *. We now have a function call less.

dmaengine: ti: k3-udma: remove non-fatal probe deferral log

2023-01-17T09:01:12Z

Drop the non-fatal probe deferral log for getting MSI domain. This makes the kernel log clean and we do not get recurring logs stating: "Failed to get MSI domain".

dmaengine: ti: k3-udma: Do conditional decrement of UDMA_CHAN_RT_PEER_BCNT_REG

2022-12-28T11:04:14Z

PSIL_EP_NATIVE endpoints may not have PEER registers for BCNT and thus udma_decrement_byte_counters() should not try to decrement these counters. This fixes the issue of crypto IPERF testing where the client side (EVM) hangs without transfer of packets to the server side, seen since this function was added.
