For modules having single clock, clk_get should be done with dev_id. But current davinci implementation handles multiple instances of the UART devices with single platform_device_register. Hence clk_get is based on con_id rather than dev_id, this is not correct. Do platform_device_register for each instance and clk_get on dev_id.
