From 0d5977d652fa5fd4e9a56127b109e5e28d4db95d Mon Sep 17 00:00:00 2001 From: Wolfgang Grandegger Date: Sat, 17 Jul 2010 16:38:48 +0200 Subject: [PATCH] MIPS: Alchemy: Define eth platform devices in the correct order Currently, the eth devices are probed in the inverse order, first au1xxx_eth1_device and then au1xxx_eth0_device. On the GPR board, this makes trouble: # ifconfig|grep HWaddr eth0 Link encap:Ethernet HWaddr 00:50:C2:0C:30:01 eth1 Link encap:Ethernet HWaddr 66:22:01:80:38:10 A bogous ethernet hwaddr is assigned to the first device and au1xxx_eth0_device is mapped to eth1, which even does not work properly. With this patch, the problems are gone: # ifconfig|grep HWaddr eth0 Link encap:Ethernet HWaddr 66:22:11:32:38:10 eth1 Link encap:Ethernet HWaddr 66:22:11:32:38:11 Signed-off-by: Wolfgang Grandegger To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/1473/ Signed-off-by: Ralf Baechle --- arch/mips/alchemy/common/platform.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/arch/mips/alchemy/common/platform.c b/arch/mips/alchemy/common/platform.c index 2580e77..f9e5622 100644 --- a/arch/mips/alchemy/common/platform.c +++ b/arch/mips/alchemy/common/platform.c @@ -435,20 +435,21 @@ static struct platform_device *au1xxx_platform_devices[] __initdata = { static int __init au1xxx_platform_init(void) { unsigned int uartclk = get_au1x00_uart_baud_base() * 16; - int i; + int err, i; /* Fill up uartclk. */ for (i = 0; au1x00_uart_data[i].flags; i++) au1x00_uart_data[i].uartclk = uartclk; + err = platform_add_devices(au1xxx_platform_devices, + ARRAY_SIZE(au1xxx_platform_devices)); #ifndef CONFIG_SOC_AU1100 /* Register second MAC if enabled in pinfunc */ - if (!(au_readl(SYS_PINFUNC) & (u32)SYS_PF_NI2)) + if (!err && !(au_readl(SYS_PINFUNC) & (u32)SYS_PF_NI2)) platform_device_register(&au1xxx_eth1_device); #endif - return platform_add_devices(au1xxx_platform_devices, - ARRAY_SIZE(au1xxx_platform_devices)); + return err; } arch_initcall(au1xxx_platform_init); -- 2.7.4
