From a79220b7633b3926a9bd3527bdac3f04dbe6845c Mon Sep 17 00:00:00 2001 From: Matej Kenda Date: Mon, 5 Mar 2007 13:06:40 +0100 Subject: [ARM] 4246/1: i2c-pxa: add adapter class to platform specific data Reposted patch for kernel 2.6.21-rc2. The driver i2c-pxa doesn't set the class member in i2c_adapter, which is used to register the I2C adapter. The hwmon (sensors) drivers (e.g. adm1021) that are connected to a i2c-pxa adapter don't attach because they expect that the adapter supports class I2C_CLASS_HWMON. This patch adds functionality to allow platforms to set the class and pass it as platform_data to the i2c-pxa driver. Sample usage in platform code: static struct i2c_pxa_platform_data my_i2c_platform_data = { .class = I2C_CLASS_HWMON }; static void __init my_platform_init(void) { (void) platform_add_devices(devices, ARRAY_SIZE(devices)); pxa_set_i2c_info(&my_i2c_platform_data); } Signed-off-by: Matej Kenda Signed-off-by: Russell King --- include/asm-arm/arch-pxa/i2c.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/asm-arm') diff --git a/include/asm-arm/arch-pxa/i2c.h b/include/asm-arm/arch-pxa/i2c.h index 46ec2243974a..e404b233d8a8 100644 --- a/include/asm-arm/arch-pxa/i2c.h +++ b/include/asm-arm/arch-pxa/i2c.h @@ -64,6 +64,7 @@ struct i2c_slave_client; struct i2c_pxa_platform_data { unsigned int slave_addr; struct i2c_slave_client *slave; + unsigned int class; }; extern void pxa_set_i2c_info(struct i2c_pxa_platform_data *info); -- cgit v1.2.2
