21  * __prci_readl() - read from a PRCI register
22  * @pd: PRCI context
23  * @offs: register offset to read from (in bytes, from PRCI base address)
26  * address of the PRCI register target described by @pd, and return
48  * @r: value read from the PRCI PLL configuration register
50  * Given a value @r read from an FU740 PRCI PLL configuration register,
91  * assemble a PRCI PLL configuration register value, and return it to
98  * Returns: a value suitable for writing into a PRCI PLL configuration
117  * __prci_wrpll_read_cfg0() - read the WRPLL configuration from the PRCI
118  * @pd: PRCI context
119  * @pwd: PRCI WRPLL metadata
122  * the PRCI identified by @pd, and store it into the local configuration
135  * __prci_wrpll_write_cfg0() - write WRPLL configuration into the PRCI
136  * @pd: PRCI context
