Hi, > Radxa ROCK Pi E25 is a Rockchip RK3568 SBC, which is there is no product called "ROCK Pi E25". it's "Radxa E25". https://wiki.radxa.com/Rock3/CM/CM3I/E25 > based on the Radxa ROCK Pi CM3 IO core board. there is no product called "Radxa ROCK Pi CM3 IO (core board)". it's "Radxa ROCK 3 Compute Module Industrial". (A.K.A. Radxa CM3I) https://wiki.radxa.com/Rock3/CM/CM3I > 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, not tested)] SATA is working on my E25. you may refer my dts, https://github.com/RadxaNaoki/linux/commits/rock-3 > - 1x User LED and 16x RGB LEDs > - 26-pin expansion header > > Signed-off-by: Chukun Pan <amadeus@xxxxxxxxxx> > --- > arch/arm64/boot/dts/rockchip/Makefile | 1 + > .../boot/dts/rockchip/rk3568-rock-pi-e25.dts | 623 ++++++++++++++++++ > 2 files changed, 624 insertions(+) > create mode 100644 arch/arm64/boot/dts/rockchip/rk3568-rock-pi-e25.dts I think dts should be separated, CM3I dtsi and E25 dts. > diff --git a/arch/arm64/boot/dts/rockchip/Makefile b/arch/arm64/boot/dts/rockchip/Makefile > index 0a76a2ebb5f6..dbf72f482636 100644 > --- a/arch/arm64/boot/dts/rockchip/Makefile > +++ b/arch/arm64/boot/dts/rockchip/Makefile > @@ -82,3 +82,4 @@ dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3568-bpi-r2-pro.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3568-evb1-v10.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3568-odroid-m1.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3568-rock-3a.dtb > +dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3568-rock-pi-e25.dtb > diff --git a/arch/arm64/boot/dts/rockchip/rk3568-rock-pi-e25.dts b/arch/arm64/boot/dts/rockchip/rk3568-rock-pi-e25.dts > new file mode 100644 > index 000000000000..f75a9cf48e02 > --- /dev/null > +++ b/arch/arm64/boot/dts/rockchip/rk3568-rock-pi-e25.dts > @@ -0,0 +1,623 @@ > +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) > + > +/dts-v1/;
