Subject: [PATCH V5 4/6] arm64: dts: qcom: ipq9574: Add PCIe PHYs and controller nodes
Date: Sun, 12 May 2024 13:58:56 +0530
Message-Id: <20240512082858.1806694-5-quic_devipriy@quicinc.com>
In-Reply-To: <20240512082858.1806694-1-quic_devipriy@quicinc.com>

Content-Transfer-Encoding: 8bit

Add PCIe0, PCIe1, PCIe2, PCIe3 (and corresponding PHY) devices
found on IPQ9574 platform. The PCIe0 & PCIe1 are 1-lane Gen3
host whereas PCIe2 & PCIe3 are 2-lane Gen3 host.

 Changes in V5:
	- Dropped anoc and snoc lane clocks from Phy nodes and enabled them
	  via interconnect.
	- Dropped msi-parent as it is handled via msi IRQ
