From 54737ba17a8444175fa94d758b83f120bbea3351 Mon Sep 17 00:00:00 2001 From: Tom Rix Date: Tue, 29 Sep 2009 10:19:49 -0400 Subject: [PATCH] TI OMAP3 Use arm init sequence to initialize i2c This changes fixes an early i2c error. 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 --- include/configs/devkit8000.h | 1 + include/configs/omap3_beagle.h | 1 + include/configs/omap3_evm.h | 1 + include/configs/omap3_overo.h | 1 + include/configs/omap3_pandora.h | 1 + include/configs/omap3_zoom1.h | 1 + include/configs/omap3_zoom2.h | 1 + 7 files changed, 7 insertions(+) diff --git a/include/configs/devkit8000.h b/include/configs/devkit8000.h index cd40da632..a8ac786c6 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 61629f8c4..55eeb947f 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 9f0f34bd8..72e962696 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 07a031bc8..154554d49 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 1cfd7e969..064c0bc69 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 61a41e725..b55b8f022 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 03f92f58e..75ab98098 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
