2022-01-24clk: at91: sama7g5: Allow MCK1 to be exported and referenced in DTGravatar Tudor Ambarus 1-0/+1
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.

2022-01-24clk: at91: allow setting PMC_AUDIOPINCK clock parents via DTGravatar Zixun LI 1-0/+1
Make AUDIOPINCK accessible via phandle to select it as peripheral clock parent using assigned-clock-parents in DT where available.

2020-12-19clk: at91: sama7g5: register cpu clockGravatar Claudiu Beznea 1-0/+1
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.
