debugfs can provide the infrastructure to trace the dependencies of clock tree hierarchy quite visibly. This patch enables to keep track of clock tree hierarchy and expose their attributes under each clock directry as below: omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/ /debug/clock/omap_32k_fck/ |-- gpt10_fck |-- gpt11_fck |-- gpt1_fck |-- per_32k_alwon_fck | |-- gpio2_fck | |-- gpio3_fck | |-- gpio4_fck | |-- gpio5_fck | |-- gpio6_fck | `-- wdt3_fck |-- ts_fck `-- wkup_32k_fck |-- gpio1_fck `-- wdt2_fck 14 directories omap:~# tree /debug/clock/omap_32k_fck/gpt10_fck/ /debug/clock/omap_32k_fck/gpt10_fck/ |-- flags |-- rate `-- usecount 0 directories, 3 files Although, compared with David Brownell's small patch, this may look bit overkilling, I expect that this debugfs can deal with other PRCM complexities at the same time. For example, powerdomain dependencies can be expressed by using symbolic links of these clocks if powerdomain supports dubgfs as well.
