Subject: [PATCH] Physical addresses fix for au1x00 serial driver
Date: Thu, 4 May 2006 12:11:12 +0200 [thread overview]
Message-ID: <20060504101112.GC19913@gundam.enneenne.com> (raw)
Hello,
here:
http://ftp.enneenne.com/pub/misc/au1100-patches/linux/patch-au1x00-serial-phys-addr
a little patch (against «linux-2.6.16-stable» branch and tested on
au1100 based board) to fix the addresses specification for the serial
driver. With this patch at boot time we get:
Serial: 8250/16550 driver $Revision: 1.90 $ 3 ports, IRQ sharing disabled
serial8250.7: ttyS0 at MMIO 0x11100000 (irq = 0) is a 16550A
serial8250.7: ttyS1 at MMIO 0x11200000 (irq = 1) is a 16550A
serial8250.7: ttyS2 at MMIO 0x11400000 (irq = 3) is a 16550A
and into procfs we read:
wwpc:~# cat /proc/iomem
10100000-10200000 : au1xxx-ohci.0
10500000-1050ffff : eth-base
10520000-10520003 : eth-mac
11100000-1110001f : serial
11200000-1120001f : serial
11400000-1140001f : serial
wwpc:~# cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16550A port:11100000 irq:0 tx:3905 rx:39 RTS|CTS|DTR|DSR|CD|RI
1: uart:16550A port:11200000 irq:1 tx:0 rx:0 CTS|DSR|CD|RI
2: uart:16550A port:11400000 irq:3 tx:0 rx:0 CTS|DSR|CD|RI
Ciao,
Rodolfo
