Subject: [PATCH] MLK-18137: fsl_lpuart: Fix loopback mode
|
|
|
|
|
|
|
|
|
|
Register offset needs to be applied on mapbase also.
|
|
|
|
|
dma_tx/rx_request use the physical address of UARTDATA.
|
|
|
|
|
Register offset is currently only applied to membase (the
|
|
|
|
|
corresponding virtual addr) but not on mapbase.
