Radxa E25 is a network application carrier board for the Radxa CM3 Industrial (CM3I) SoM, which is based on the Rockchip RK3568 SoC. It has the following features: - MicroSD card socket, on board eMMC flash - 2x 2.5GbE Realtek RTL8125B Ethernet transceiver - 1x USB Type-C port (Power and Serial console) - 1x USB 3.0 OTG port - mini PCIe socket (USB or PCIe) - ngff PCIe socket (USB or SATA) - 1x User LED and 16x RGB LEDs - 26-pin expansion header Installation: Uncompress the OpenWrt sysupgrade and write it to a micro SD card or internal eMMC using dd.

Subject: [PATCH] arm64: dts: rockchip: Fix PCIe regulators on Radxa E25
|
|
|
|
Despite its name, the regulator vcc3v3_pcie30x1 has nothing to do with
|
|
pcie30x1. Instead, it supply power to VBAT1-5 on the M.2 KEY B port as
|
|
seen on page 8 of the schematic [1].
|
|
|
|
pcie30x1 is used for the mini PCIe slot, and as seen on page 9 the
|
|
vcc3v3_minipcie regulator is instead related to pcie30x1.
|
|
|
|
The M.2 KEY B port can be used for WWAN USB2 modules or SATA drives.
|
|
|
|
Use correct regulator vcc3v3_minipcie for pcie30x1.
