From: Romain Naour <romain.naour@xxxxxxx> The ACSPCIE_PROXY_CTRL registers within the CTRL_MMR space of TI's J721e SoC are used to drive the reference clock to the PCIe Endpoint device via the PAD IO Buffers. Add the compatible for allowing the PCIe driver to obtain the regmap for the ACSPCIE_CTRL register within the System Controller device-tree node in order to enable the PAD IO Buffers.
