WebOct 18, 2024 · However, the most likely candidate to trigger that parent change is a call to clk_set_rate(), with determine_rate() figuring out which parent is the best suited for a given rate. The other trigger would be a call to clk_set_parent(), but it's far less used, and it doesn't look like there's any obvious user for that clock.

"WebApr 8, 2013 · This patch adds a common clock driver for Silicon Labs Si5351a/b/c i2c programmable clock generators. Currently, the driver does not support VXCO feature of si5351b. Passing platform_data or DT bindings selectively allow to overwrite stored Si5351 configuration which is very helpful for clock generators with empty eeprom configuration. " - Struct clk_hw
