It appears that I2C is working because once a read or write error is detected, the omap24xx_i2c driver calls i2c_init inside its error handling check. While it is ok to attempt error handling this way, the boards must not depend on this side effect to initialize it's i2c. Instead of explicitly calling i2c_init for every board, use the generic arm initialization in lib_arm/board.c. By defining the config variable CONFIG_HARD_I2C, the omap3 i2c initialization is included in the init_sequence table. Run tested on Beagle. Compile tested on the omap3's Signed-off-by: Tom Rix Acked-by: Dirk Behme --- diff --git a/include/configs/devkit8000.h b/include/configs/devkit8000.h index cd40da6320..a8ac786c64 100644 --- a/include/configs/devkit8000.h +++ b/include/configs/devkit8000.h @@ -98,6 +98,7 @@ #define CONFIG_DOS_PARTITION 1 /* I2C */ +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0 diff --git a/include/configs/omap3_beagle.h b/include/configs/omap3_beagle.h index 61629f8c4a..55eeb947fe 100644 --- a/include/configs/omap3_beagle.h +++ b/include/configs/omap3_beagle.h @@ -123,6 +123,7 @@ #undef CONFIG_CMD_NFS /* NFS support */ #define CONFIG_SYS_NO_FLASH +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0 diff --git a/include/configs/omap3_evm.h b/include/configs/omap3_evm.h index 9f0f34bd85..72e9626963 100644 --- a/include/configs/omap3_evm.h +++ b/include/configs/omap3_evm.h @@ -121,6 +121,7 @@ #undef CONFIG_CMD_IMLS /* List all found images */ #define CONFIG_SYS_NO_FLASH +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0 diff --git a/include/configs/omap3_overo.h b/include/configs/omap3_overo.h index 07a031bc87..154554d49a 100644 --- a/include/configs/omap3_overo.h +++ b/include/configs/omap3_overo.h @@ -109,6 +109,7 @@ #undef CONFIG_CMD_NFS /* NFS support */ #define CONFIG_SYS_NO_FLASH +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0 diff --git a/include/configs/omap3_pandora.h b/include/configs/omap3_pandora.h index 1cfd7e9694..064c0bc690 100644 --- a/include/configs/omap3_pandora.h +++ b/include/configs/omap3_pandora.h @@ -112,6 +112,7 @@ #undef CONFIG_CMD_NFS /* NFS support */ #define CONFIG_SYS_NO_FLASH +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0 diff --git a/include/configs/omap3_zoom1.h b/include/configs/omap3_zoom1.h index 61a41e7255..b55b8f0222 100644 --- a/include/configs/omap3_zoom1.h +++ b/include/configs/omap3_zoom1.h @@ -119,6 +119,7 @@ #undef CONFIG_CMD_NFS /* NFS support */ #define CONFIG_SYS_NO_FLASH +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0 diff --git a/include/configs/omap3_zoom2.h b/include/configs/omap3_zoom2.h index 03f92f58e7..75ab98098c 100644 --- a/include/configs/omap3_zoom2.h +++ b/include/configs/omap3_zoom2.h @@ -140,6 +140,7 @@ #undef CONFIG_CMD_NFS /* NFS support */ #define CONFIG_SYS_NO_FLASH +#define CONFIG_HARD_I2C 1 #define CONFIG_SYS_I2C_SPEED 100000 #define CONFIG_SYS_I2C_SLAVE 1 #define CONFIG_SYS_I2C_BUS 0
