+ * The APM X-Gene PHY consists of two PLL clock macro's (CMU) and lanes.
+ * The first PLL clock macro is used for internal reference clock. The second
+ * PLL clock macro is used to generate the clock for the PHY. This driver
+ * configures the first PLL CMU, the second PLL CMU, and programs the PHY to
+ * operate according to the mode of operation. The first PLL CMU is only
+ * required if internal clock is enabled.
+ *
+ * Logical Layer Out Of HW module units:
+ *
+ * -----------------
+ * | Internal      |    |------|
+ * | Ref PLL CMU   |----|      |     -------------    ---------
+ * ------------ ----    | MUX  |-----|PHY PLL CMU|----| Serdes|
+ *                      |      |     |           |    ---------
+ * External Clock ------|      |     -------------
+ *                      |------|
+ *
+ * The Ref PLL CMU CSR (Configuration System Registers) is accessed
+ * indirectly from the SDS offset at 0x2000. It is only required for
+ * internal reference clock.
+ * The PHY PLL CMU CSR is accessed indirectly from the SDS offset at 0x0000.
+ * The Serdes CSR is accessed indirectly from the SDS offset at 0x0400.
+ *
+ * The Ref PLL CMU can be located within the same PHY IP or outside the PHY IP
+ * due to shared Ref PLL CMU. For PHY with Ref PLL CMU shared with another IP,
+ * it is located outside the PHY IP. This is the case for the PHY located
+ * at 0x1f23a000 (SATA Port 4/5). For such PHY, another resource is required
+ * to located the SDS/Ref PLL CMU module and its clock for that IP enabled.
+ *
+ * Currently, this driver only supports Gen3 SATA mode with external clock.
