The PCIe reference clock required by the PCIe Endpoints connected to the PCIe connector corresponding to the PCIe1 instance of PCIe on J784S4-EVM is driven by the ACSPCIE module. Add the device-tree support for enabling the same. Signed-off-by: Siddharth Vadapalli <s-vadapalli@ti.com> --- Hello, This patch is based on linux-next tagged next-20240930.
