Hi,
Has any one used LPC47M10x's internal UART.Its Data sheet says it has two NS16450 compatible UART inside it.

1. I could identify LPC47M10x driver in the kernel.But that driver appears to be for 'Hardware monitoring' and power control.
2. I could read the Device ID '0x59' ( address 0x20 )over the LPC lines ( EP80579 , Intel).
3. I could also read OSC default vale as '0x44'.

WHAT IS THE BASE ADDRESS FOR SERIAL 1 ( Device 4 for LPC47M10x )?

While accessing the configuration register ( Like Line control register (LCR) or LSR line status register) WHICH BASE ADDRESS SHD BE USED ?
is it the value present at '0x60' and '0x61'( Primary Base I/O address ) or some thing else.

In my case Base address come out to be 0x220 (Device 4) 0x228 (Device 5).
