2025-05-21clk: thead: Port clock controller driver of TH1520 SoCYao Zi
The driver is adapted from Linux kernel's version of clk-th1520-ap.c, with only output clocks for external sensors, which are barely useful in bootloaders, removed. Same as the mainline driver, it currently lacks of ability to enable and reconfigure PLLs, which could be implemented later.

2025-04-01clk: airoha: Add support for Airoha AN7581 SoC clockChristian Marangi
Add support for Airoha AN7581 SoC clock driver. This mainly needed for eMMC support to correctly get the current clock applied. Based on the Linux clk-en7523.c but majorly reworked for U-Boot that doesn't require CCF subsystem. Major modification, support for set_rate, realtime get_rate and split for reset part to a different driver. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
2025-02-26clk: add stub clock driverCaleb Connolly
Add a stub clock driver which can be used to bind clock controllers which aren't required for the platform to boot, but which are needed for U-Boot drivers to work. In addition, add a NOP parent driver to allow for binding the parent nodes of the clock. Initially this driver supports a Qualcomm platform where the MMC driver tries to fetch the RPM clock controller, which is not actually required for the device to work.

Moreover, it is agnostic to the alias numbering as the information about the clock is read from the device tree.
