+ *
+ * The PM3393 has three types of components that are

+ *
+ * DRESETB - Digital circuitry
+ * PL4_ARESETB - PL4 analog circuitry
+ * XAUI_ARESETB - XAUI bus analog circuitry
+ *
+ * Steps to reset PM3393 using RSTB pin:
+ *
+ * 1. Assert RSTB pin low ( write 0 )
+ * 2. Wait at least 1ms to initiate a complete initialization of device.
+ * 3. Wait until all external clocks and REFSEL are stable.
+ * 4. Wait minimum of 1ms. (after external clocks and REFEL are stable)
+ * 5. De-assert RSTB ( write 1 )
+ * 6. Wait until internal timers to expires after ~14ms.
+ * - Allows analog clock synthesizer(PL4CSU) to stabilize to
+ * selected reference frequency before allowing the digital
+ * portion of the device to operate.
+ * 7. Wait at least 200us for XAUI interface to stabilize.
+ * 8. Verify the PM3393 came out of reset successfully.
+ * Set successful reset flag if everything worked else try again
+ * a few more times.
