Hi All, I tried using the 8250 Uart driver on DM355 for communicating with the audio codec but it seems that uart driver is heavily dependent on the tty driver. I don't want to use the tty later as it makes the auido codec driver more complex and difficult to maintain.
I just want to make following functions: 1. uart_register_port(sturct uart_port *port); 2. uart_configure(int line, int baud, int parity, int flow); 3. uart_write(int line, char* data, int count); 4. uart_read(int line, char* data, int count); Can anyone please suggest me how do I do it. I tried using the 8250 layer directly but it seems that the interrupt handler is also dependent on the tty layer. How do I make uart layer independent on the tty layer.... something similar to i2c structure of the linux... Please help...
