Re: enabling uart2 on omap5912 osk

hi,

i have changed the line in omap_osk.c to:

static struct omap_uart_config osk_uart_config __initdata = {
      .enabled_uarts = ((1 << 0) | (1 << 1) | (1 << 2)),
};

And all the three UARTs are enabled now as i can see in the kernel boot-log:

serial8250.0: ttyS0 at MMIO 0xfffb0000 (irq = 46) is a ST16654
serial8250.0: ttyS1 at MMIO 0xfffb0800 (irq = 47) is a ST16654
serial8250.0: ttyS2 at MMIO 0xfffb9800 (irq = 15) is a ST16654

A node called ttyS0 is already there which is linked to uart0.

when i type:

ls -l /dev/ttyS0
crw-rw-rw-    1 root     root       4,  64 Aug  8  2004
\0x1b[1;35m/dev/ttyS0\0x1b[0m
# ls -l /dev/ttyS1
-rw-r--r--    1 root     root           16 May 21  2008
\0x1b[0;0m/dev/ttyS1\0x1b[0m

i have a question on the above output. the major and minor number for
ttyS0 are 4, 64 but fot ttyS1 i dont find a major number. what does
this indicate?

thanx for all the help.

regards,
Shareef
