The au1000-eth platform data can be overriden with the au1xxx_override_eth_cfg function like it has to be done for the Bosporus board which uses a different MAC/PHY setup. Changes from v3: - declare a static au1000_eth_platform_data structure for bosporus and initialize it - remove parenthis and bit shifting on SYS_PF_NI2 Changes from v2: - declared the au1000-eth second driver instance platform_data - made the override function generic and pass it the port number too Changes from v1: - remove per-board platform.c file - add an override function to pass custom eth0 platform_data PHY settings Signed-off-by: Florian Fainelli --- diff --git a/arch/mips/alchemy/common/platform.c b/arch/mips/alchemy/common/platform.c index 3be14b0..3fbe30c 100644 --- a/arch/mips/alchemy/common/platform.c +++ b/arch/mips/alchemy/common/platform.c @@ -19,6 +19,7 @@ #include #include #include +#include #define PORT(_base, _irq) \ { \ @@ -326,6 +327,88 @@ static struct platform_device pbdb_smbus_device = { };
