The ADIS16550 is a complete inertial system that includes a triaxis
gyroscope and a triaxis accelerometer. Each inertial sensor in the
ADIS16550 combines industry leading MEMS only technology with signal
conditioning that optimizes dynamic performance. The factory calibration
characterizes each sensor for sensitivity, bias, and alignment. As a
result, each sensor has its own dynamic compensation formulas that
provide accurate sensor measurements.

When users query driver diagnosis information on the BMC, the driver
detects the query request in the scheduled task and reports
driver statistics and link status to the BMC through the bar space.

In hw_adjus_link(), the core_reset is added to try to

In addition, MAC link failure detection is added.
If the MAC link fails after core_reset, driver invokes
