I would like to know if there is any development work under way to support these devices and if so whom I could contact about it: 1) Marvell GT-64260A (Gallileo System Controller for PowerPC) as I2C Bus Master. 2) Phillips PCA9557 & PCA9557a 8-bit I2C and SMBUS I/O port with interrupt. 3) Phillips PCA9554 & PCA9554a 8-bit I2C and SMBUS I/O port with interrupt. And a general question I did not see in the FAQ. In the lm_sensors/kernel/chips/lm87.c module the lm87_attach_adapter function is notably different from other chip's counterparts in that it makes a copy of the static i2c_client_address_data structure and calls the function "i2c_probe" using that copy. It saves the return status of this function call then goes ahead and calls the i2c_detect function (as do all the other modules I have looked at) but then returns not with the status from the i2c_detect call, but the one returned from the i2c_probe call. Why this difference? From examining the code in i2c_detect vs i2c_probe it wasn't obvious what the difference between these two functions are. Can anyone elaborate for me? Thanks, Dave Spain SkyComputers
