This patch removes support for user-provided platform-specific hardware reset and clock starting/stopping functions. Hardware reset was needed earlier as getting the software reset working was tricky due to the lack of documentation. Recently, a number of people using isp116x have said the software reset is working for them. I haven't heard of anybody using the clock starting/stopping.
