I've applied this, but I now get the following warnings when building
the code:
drivers/serial/pch_uart.c: In function ‘dma_handle_rx’:
drivers/serial/pch_uart.c:685:24: warning: cast from pointer to integer of different size
drivers/serial/pch_uart.c: In function ‘dma_handle_tx’:
drivers/serial/pch_uart.c:778:23: warning: cast from pointer to integer of different size
drivers/serial/pch_uart.c: In function ‘pch_uart_init_port’:
drivers/serial/pch_uart.c:1289:20: warning: cast to pointer from integer of different size
drivers/serial/pch_uart.c: In function ‘pch_uart_exit_port’:
drivers/serial/pch_uart.c:1328:2: warning: cast from pointer to integer of different size

Please send me a follow-up patch to resolve this.

thanks,
