Subject: [PATCH v6 02/11] arm64: dts: qcom: ipq5210: Introduce RDP504 common DT file
Date: Thu, 08 Oct 2026 14:44:22 +0530 [thread overview]
Message-ID: <20261008-08-dts-v6-2-f9c4ec8664d8@oss.qualcomm.com> (raw)
In-Reply-To: <20261008-08-dts-v6-0-f9c4ec8664d8@oss.qualcomm.com>
RDP504 has USB, PCIe and SPI NAND devices populated. EMMC and NAND
share the GPIOs. The board has to be reworked to change from EMMC
to NAND variant. Rename ipq5210-rdp504.dts as ipq5210-rdp504-common.dtsi
and include it in variant specific DTS file.
Describe the fixed USB regulators, PCIe reset GPIOs, QPIC SPI NAND flash
and required pinctrl states. Enable QPIC BAM, USB and PCIe for the board.
