1248 * Sierra PHY has 2 PLLs, viz. PLLLC and PLLLC1. So in this case, PLLLC is used for PCIe
1249 * and PLLLC1 is used for QSGMII. PHY is configured in two steps as described below.
1251 * [1] For first step, phy_t1 = TYPE_PCIE and phy_t2 = TYPE_QSGMII
1252 * So the register values are selected as [TYPE_PCIE][TYPE_QSGMII][ssc].
1253 * This will configure PHY registers associated for PCIe (i.e. first protocol)
1254 * involving PLLLC registers and registers for first 2 lanes of PHY.
1255 * [2] In second step, the variables phy_t1 and phy_t2 are swapped. So now,
1256 * phy_t1 = TYPE_QSGMII and phy_t2 = TYPE_PCIE. And the register values are selected as
1257 * [TYPE_QSGMII][TYPE_PCIE][ssc].

1259 * involving PLLLC1 registers and registers for other 2 lanes of PHY.
