Hello, the attached patch introduces an ioctl function pointer in the i2c_driver structure. This is functionally equivalent to the actual command function but with different scope: - ioctl shall be used to send STANDARD ioctls to devices - command shall be used to send SPECIFIC commands to devices The actual command function is used only by some rtc and media drivers, with mixed implementation. i2c_clients_command will send a command to every device, regardless of the implementation. This could lead to a situation in which an rtc driver receives a command meant for a tuner device. The attached patch also corrects the relevant client drivers to appropriately use each interface. i2c_clients_command has been renamed i2c_clients_ioctl. The i2c core still misses a function to send a command or an ioctl directly to a specific device, but it is something I'd like to address in the short term. If this gets approved, I plan to write a generic high-layer rtc device which can use any of the low level i2c rtc drivers as the system rtc. This will be used on a number of embedded devices, like the Linksys NSLU2 and the Iomega NAS100D. Please note that this patch applies only OVER Jean's current stack.
