AM6442: Generating PCIe Clock from AM6442

Part Number: AM6442

Tool/software:

Hello everyone,

We have designed our own hardware based on the AM64x. Unlike the EVM, the design does not include a clock buffer for PCIe, so we need to generate the clock from the AM64 itself.

We have identified the following configuration in the device tree:

ti,syscon-pcie-refclk-out: $ref: /schemas/types.yaml#/definitions/phandle-array items: - items: - description: Phandle to the SYSCON entry - description: lock2_kick0 register offset within SYSCON - description: lock2_kick1 register offset within SYSCON - description: acspcie_ctrl register offset within SYSCON - description: pcie_refclk_clksel register offset within SYSCON - description: clock source index to source ref clock description: Specifier for enabling the ACSPCIE clock buffer for reference clock output.

We would like to know where the different offsets are defined. On https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1340937/am68a-enable-internal-pcie-clock an xlsx is referenced. Can we use it for am6442 or is there any for am6442 ? Could someone please point me to the location of this file or provide any other relevant information?

Thank you in advance for your help!

Best regards,

Rémi
