Subject: [PATCH V2 8/9] arm64: dts: qcom: ipq9574: Enable PCIe PHYs and controllers
Date: Tue, 4 Apr 2023 22:18:27 +0530 [thread overview]
Message-ID: <20230404164828.8031-9-quic_devipriy@quicinc.com> (raw)
In-Reply-To: <20230404164828.8031-1-quic_devipriy@quicinc.com>
Enable the PCIe controller and PHY nodes corresponding to
RDP 433
Signed-off-by: Devi Priya <quic_devipriy@quicinc.com>
---
Changes in V2:
- Moved the Board DT changes to a new patch as suggested
- Added pinctrl definitions for PCIe perst GPIOs
- Dropped the suffix denoting the lane config from pcie labels
