Subject: [RFC PATCH 0/2] Enable PCIe1 on J7AHP
Date: Tue, 5 Sep 2023 17:18:14 +0530	[thread overview]
Message-ID: <20230905114816.2993628-1-a-verma1@ti.com> (raw)

PCIe1 instance on J7AHP EVM EP connector has reference clock connection
from serdes unlike PCIe0 for which reference clock connection is from
on-board clock generator. To enable PCIe1 instance, ACSPCIE clock buffer
pads have to be enabled to get reference clock output available to PCIe1 EP

This enables clock source select and ACSPCIE clock buffer pads.

Achal Verma (2):
  dt-bindings: PCI: ti,j721e-pci-*: Add "ti,syscon-pcie-refclk-out"
    property
  pci: j721e: Enable reference clock output from serdes
