* clk: si570: Skip NVM to RAM recall operation if an optional property is setSaeed Nowshadi2021-02-111-4/+12
| | | | | | | | | | | | | | Recalling NVM data into RAM during probe() initiates a re-calibration of the clock. If the clock is already in-use, the recall operation can cause a glitch on the frequency out. At power on, the factory data are loaded from NVM into RAM by default. If the clock frequency has been changed since power on, the recall operation can be used to re-initialize the clock to factory setting.

* clk: si570: Migrate to clk_hw based OF and registration APIsStephen Boyd2016-08-241-7/+6
| | | | | | | | | | | | Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs.
