Enable the PCIe controller and PHY nodes corresponding to RDP466. The IPQ5424 RDP466 does not have a wake gpio because it does not support low power mode. It only supports a perst gpio. Signed-off-by: Manikanta Mylavarapu <quic_mmanikan@quicinc.com> --- Changes in V7: - Incorporated the information about the absence of wake GPIO support into the commit message. arch/arm64/boot/dts/qcom/ipq5424-rdp466.dts | 41 ++++++++++++++++++++- 1 file changed, 40 insertions(+), 1 deletion(-)
