From: "Chiam, Evon" <evon.chiam@altera.com>
This series adds Clock Manager support for the Altera SoCFPGA Agilex72
platform. It also moves the Agilex72 device trees under dts/altera and
switches the board/SoC compatible strings to the "altr" vendor prefix,
matching Agilex7m and vendor-prefixes.yaml.
The Agilex72 clock manager exposes multiple register regions (clkmgr and
three GPPLLs) and provides the peripheral clocks used by the SoC. The
driver registers the PLL, peripheral, and gate clock tree, while the DT
describes the external input references and the clock manager node.
Patch summary:
1/5: Fix Agilex72 compatible strings in the altera DT binding
2/5: Add Agilex72 clock manager DT binding and clock ID header
3/5: Add Agilex72 clock manager driver
4/5: Move Agilex72 DT from dts/intel to dts/altera and use altr
5/5: Add clock manager and input clocks to the Agilex72 DT

Altera has separated from Intel. Update the Agilex72 SoC and board
compatible strings to use the Altera vendor prefix instead of intel.

Move the Agilex72 SoC and SoCDK device trees from dts/intel to
dts/altera. Update the board and SoC compatible strings to use
the "altr" vendor.

wire the UART clocks through the clock manager instead of a fixed
clock. Set the SoCDK board-specific input clock frequencies.
