title: Mapping UART register address to kernel for writing device drivers
body: <p>How will I map register addresses specifically UART registers to kernel for writing device drivers for UART?</p>
  
  <p>I have gone through the omap-serial.c.But I did not find the mapping of the registers defined in it.</p>
  
  <p>Is it different from the mapping of standalone UART driver?</p>
