Subject: IBM ocp I2C circular dependency
Date: Tue, 07 May 2002 15:02:04 +0200 [thread overview]
Message-ID: <3CD7D04C.1E9122A0@etx.ericsson.se> (raw)
i2c-adap-ibm_ocp.c uses
i2c_iic_add_bus and i2c_iic_del_bus from i2c-algo-ibm_ocp.c
i2c-algo-ibm_ocp.c uses
iic_ibmocp_waitforpin from i2c-adap-ibm_ocp.c
This makes it impossible to build as a module. I'am not shure how you want to
solv this.
Also I found a problem with the code when I access a i2c memory from
userspace and no chip is present at that address. After that it's not
possible to access anything else on the I2C bus. Works OK as long as I use
addresses that have a device that answers (I think).
