Set I2C bus frequency

Hello, 
i'd like to configure I2C bus speed to 400kHz (kernel 2632rc8). 
Setting the fastmode-flag (FM) in makro I2C_INIT still gives me "init i2c
-> 98kHz" at sytem boot. 

Anyone can help? 

Thanks alot

Google <linux i2c speed>

turns up this:

http://comments.gmane.org/gmane.linux.ports.arm.kernel/90888

possibly gives some clues about what would need to be done. Tried throwing
Samsung in the mix, but couldn't see anything.

I'll ask around at work , but don't think anyone is driving I2C devices on
the ARM (S3C2410) platform.

You can change: arch/arm/plat-s3c/dev-i2c0.c (line 53). anyway not
experienced in i2c but one i2c bus is connected EEPROM. Anyway not sure if
there's second i2c (if yes you need to create device for it ;))

Hello,

Thanks all.

i now changed i2c-s3c2410.c
There, clock is calculated, i passed 400k instead of 100k and it works.
Maybe bus speed can be set earlier somewhere...

Also important: msleep(1) functions are called there. Causing quite heavy
delays as function is slow; replaced them with udelay(1000), works much
faster now.

Just passed this link:

but sounds like you got your solution!
