How tty driver interacts with UART driver during read/write opetations?

Question

I am working on modification/development of a SDIO UART driver.
And would like to know:

How tty driver interacts with UART driver during read/write operations? I am interested in buffer management.

I searched over net, however did not find necessary information.
Can somebody throw some light on this?

Thank you in advance.

Following links helped me understand TTY layer operations. TTY driver's read/write operations are little tricky to understand though..
