[patch v3 0/5] *** DMA based UART driver for AST2500 ***

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: sudheer veliseti <sudheer.open@xxxxxxxxx>

Hi,
AST2500 has dedicated Uart DMA controller which has 12 sets of
Tx and RX channels connected to UART controller directly.
Since the DMA controller have dedicated buffers and registers,
there would be little benifit in adding DMA framework overhead.
So the software for DMA controller is included within the UART driver itself.

Thanks and Regards

changes in v3:
- custom debugs replaced with pr_debug in 8250_ast2500_uart_dma.c
- change logs added in patches
