From c5cb6b2df5fa914f57a36b7b03b01a4d9d29030f Mon Sep 17 00:00:00 2001 From: Bo Shen Date: Mon, 15 Oct 2012 17:30:27 +0800 Subject: [PATCH] ARM: at91/i2c: change id to let i2c-gpio work commit 7840487cd6298f9f931103b558290d8d98d41c49 upstream. The i2c core driver will turn the platform device ID to busnum When using platfrom device ID as -1, it means dynamically assigned the busnum. When writing code, we need to make sure the busnum, and call i2c_register_board_info(int busnum, ...) to register device if using -1, we do not know the value of busnum In order to solve this issue, set the platform device ID as a fix number Here using 0 to match the busnum used in i2c_regsiter_board_info() Signed-off-by: Bo Shen Acked-by: Jean Delvare Signed-off-by: Nicolas Ferre Acked-by: Jean-Christophe PLAGNIOL-VILLARD Acked-by: Ludovic Desroches Signed-off-by: Ben Hutchings --- arch/arm/mach-at91/at91rm9200_devices.c | 2 +- arch/arm/mach-at91/at91sam9260_devices.c | 2 +- arch/arm/mach-at91/at91sam9261_devices.c | 2 +- arch/arm/mach-at91/at91sam9263_devices.c | 2 +- arch/arm/mach-at91/at91sam9rl_devices.c | 2 +- 5 files changed, 5 insertions(+), 5 deletions(-) diff --git a/arch/arm/mach-at91/at91rm9200_devices.c b/arch/arm/mach-at91/at91rm9200_devices.c index 143eebbef6fe0..929fd913e555e 100644 --- a/arch/arm/mach-at91/at91rm9200_devices.c +++ b/arch/arm/mach-at91/at91rm9200_devices.c @@ -462,7 +462,7 @@ static struct i2c_gpio_platform_data pdata = { static struct platform_device at91rm9200_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; diff --git a/arch/arm/mach-at91/at91sam9260_devices.c b/arch/arm/mach-at91/at91sam9260_devices.c index 25909884422b5..465e026fbf517 100644 --- a/arch/arm/mach-at91/at91sam9260_devices.c +++ b/arch/arm/mach-at91/at91sam9260_devices.c @@ -467,7 +467,7 @@ static struct i2c_gpio_platform_data pdata = { static struct platform_device at91sam9260_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; diff --git a/arch/arm/mach-at91/at91sam9261_devices.c b/arch/arm/mach-at91/at91sam9261_devices.c index daf3e66cfe1d4..d6d1e769c2bc4 100644 --- a/arch/arm/mach-at91/at91sam9261_devices.c +++ b/arch/arm/mach-at91/at91sam9261_devices.c @@ -284,7 +284,7 @@ static struct i2c_gpio_platform_data pdata = { static struct platform_device at91sam9261_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; diff --git a/arch/arm/mach-at91/at91sam9263_devices.c b/arch/arm/mach-at91/at91sam9263_devices.c index 32a7e4339107c..e051376e47643 100644 --- a/arch/arm/mach-at91/at91sam9263_devices.c +++ b/arch/arm/mach-at91/at91sam9263_devices.c @@ -540,7 +540,7 @@ static struct i2c_gpio_platform_data pdata = { static struct platform_device at91sam9263_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; diff --git a/arch/arm/mach-at91/at91sam9rl_devices.c b/arch/arm/mach-at91/at91sam9rl_devices.c index 628eb566d60ce..4862b23ac82e4 100644 --- a/arch/arm/mach-at91/at91sam9rl_devices.c +++ b/arch/arm/mach-at91/at91sam9rl_devices.c @@ -319,7 +319,7 @@ static struct i2c_gpio_platform_data pdata = { static struct platform_device at91sam9rl_twi_device = { .name = "i2c-gpio", - .id = -1, + .id = 0, .dev.platform_data = &pdata, }; -- 2.47.3
