A standard high-speed 1.5 GHz input clock of SATA_PHY is provided by the DPLL_SATA.CLKDCOLDO output. PRCM. SATA_REF_GFCLK ( derived from the SYS_CLK) should be enabled, to provide the necessary DPLL_SATA and SATA_PHY clocking within the SATA subsystem.
Depending on the SATA_REF_GFCLK (SYS_CLK derived) frequency, following settings should be made in the CTRL_MODULE_CORE.CONTROL_PHY_POWER_SATA[31:22] SATA_PWRCTL_CLK_FREQ bitfield for proper operation:
