clk/sifive/fu540-prci.c

16  * The FU540 PRCI implements clock and reset control for the SiFive
18  * over all PRCI resources.
20  * This driver is based on the PRCI driver written by Wesley Terpstra:
27 #include <dt-bindings/clock/sifive-fu540-prci.h>
140  * @va: base virtual address of the PRCI IP block
143  * PRCI per-device instance data
155  * @cfg0_offs: WRPLL CFG0 register offset (in bytes) from the PRCI base address
169  * struct __prci_clock - describes a clock device managed by PRCI
175  * @pd: PRCI-specific data associated with this clock (if not NULL)
177  * PRCI clock data.  Used by the PRCI driver to register PRCI-provided
196  * __prci_readl() - read from a PRCI register
197  * @pd: PRCI context
198  * @offs: register offset to read from (in bytes, from PRCI base address)
201  * address of the PRCI register target described by @pd, and return
223  * @r: value read from the PRCI PLL configuration register
225  * Given a value @r read from an FU540 PRCI PLL configuration register,
266  * assemble a PRCI PLL configuration register value, and return it to
273  * Returns: a value suitable for writing into a PRCI PLL configuration
292  * __prci_wrpll_read_cfg() - read the WRPLL configuration from the PRCI
293  * @pd: PRCI context
294  * @pwd: PRCI WRPLL metadata
297  * the PRCI identified by @pd, and store it into the local configuration
310  * __prci_wrpll_write_cfg() - write WRPLL configuration into the PRCI
311  * @pd: PRCI context
312  * @pwd: PRCI WRPLL metadata
316  * configuration register identified by @pwd in the PRCI instance
336  * @pd: struct __prci_data * for the PRCI containing the CORECLK mux reg
356  * @pd: struct __prci_data * for the PRCI containing the CORECLK mux reg
463  * PRCI integration data for each WRPLL instance
481  * List of clock controls provided by the PRCI
511  * __prci_register_clocks() - register clock controls in the PRCI with Linux
