4 Subject: [PATCH] ENGR00157473 MX5X: UART: disable UART2 DMA to make GPS work.
6 After enable DMA, GPS will keep report these DMA error:
8 UART: DMA_ERROR: sr1:2010 sr2:508b
9 UART: DMA_ERROR: sr1:2050 sr2:508a
10 UART: DMA_ERROR: sr1:2050 sr2:508b
11 UART: DMA_ERROR: sr1:10 sr2:1083
12 UART: DMA_ERROR: sr1:50 sr2:1082
13 UART: DMA_ERROR: sr1:2010 sr2:508b
14 UART: DMA_ERROR: sr1:2050 sr2:508a
15 UART: DMA_ERROR: sr1:2010 sr2:508b
16 UART: DMA_ERROR: sr1:2010 sr2:508b
17 UART: DMA_ERROR: sr1:2010 sr2:508b
18 UART: DMA_ERROR: sr1:50 sr2:1083
