dt-bindings: clock: Add SAMA7D65 PMC compatible string

2024-12-17T08:10:21Z

Add the `microchip,sama7d65-pmc` compatible string to the existing binding, since the SAMA7D65 PMC shares the same properties and clock requirements as the SAMA7G5. Export MCK3 and MCK5 to be accessed and referenced in DT to assign to the clocks property for sama7d65 SoC.

dt-bindings: clk: at91: Add clock IDs for the slow clock controller

2024-12-08T15:55:26Z

Add clock IDs for the slow clock controller. Previously, raw numbers were used (0 or 1) for clocks generated by the slow clock controller. This leads to confusion and wrong IDs were used on few device trees. To avoid this add macros.

clk: at91: sama7g5: Allow MCK1 to be exported and referenced in DT

2022-01-25T01:05:45Z

MCK1 feeds the External Bus Interface (EBI). EBI's clock rate is used to translate EBI's timmings to SMC timings, thus we need to handle MCK1 in the EBI driver. Allow MCK1 to be referenced as a PMC_TYPE_CORE clock from phandle in DT.

clk: at91: sama7g5: register cpu clock

2020-12-19T19:50:56Z

Register CPU clock as being the master clock prescaler. This would be used by DVFS. The block schema of SAMA7G5's PMC contains also a divider between master clock prescaler and CPU (PMC_CPU_RATIO.RATIO) but the frequencies supported by SAMA7G5 could be directly received from CPUPLL + master clock prescaler and the extra divider would do no work in case it would be enabled.
