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,
