A future patch will implement a clock uclass driver for Tegra. That driver will call into Tegra's existing clock code to simplify the transition; this avoids tieing the clock uclass patches into significant refactoring of the existing custom clock API implementation. Some of the Tegra clock APIs that manipulate peripheral clocks require both the peripheral clock ID and parent clock ID to be passed in together. However, the clock uclass API does not require any such "parent" parameter, so the clock driver must determine this information itself. This patch implements new Tegra- specific clock API clock_get_periph_parent() for this purpose. The new API is implemented in the core Tegra clock code rather than SoC- specific clock code. The implementation uses various SoC-/clock-specific data. That data is only available in SoC-specific clock code. Consequently, two new internal APIs are added that enable the core clock code to retrieve this information from the SoC-specific clock code. Due to the structure of the Tegra clock code, this leads to some unfortunate code duplication. However, this situation predates this patch. Ideally, future work will de-duplicate the Tegra clock code, and migrate it into drivers/clk/tegra. However, such refactoring is kept separate from this series.
