MIPS: Add Mobileye EyeQ6Lplus evaluation board dts

2026-04-13T13:31:41+00:00

Add the device tree of the evaluation board of the EyeQ6Lplus SoC. The board comes with 2GB of RAM and an SPI NAND connected to the octoSPI controller The UART of the SoC is used as the serial console. Signed-off-by: Benoît Monin Signed-off-by: Thomas Bogendoerfer

MIPS: Add Mobileye EyeQ6Lplus SoC dtsi

2026-04-13T13:31:41+00:00

Add the device tree include files for the EyeQ6Lplus system on chip from Mobileye. Those files provide the initial support of the SoC: * The I6500 CPU and GIC interrupt controller. * The OLB ("Other Logic Block") providing clocks, resets and pin controls. * One UART. * One GPIO controller. * Two SPI controllers, one in host mode and one in target mode. * One octoSPI flash controller. * Two I2C controllers.

MIPS: dts: loongson64g-package: Switch to Loongson UART driver

2026-04-06T12:14:24+00:00

Loongson64g is Loongson 3A4000, whose UART controller is compatible with Loongson 2K1500, which is NS16550A-compatible with an additional fractional frequency divisor register. Update the compatible strings to reflect this, so that 3A4000 can benefit from the fractional frequency divisor provided by loongson-uart. This is required on some devices, otherwise their UART can't work at some high baud rates, e.g., 115200. Tested on Loongson-LS3A4000-7A1000-NUC-SE with a 25MHz UART clock. Without fractional frequency divisor, the actual baud rate was 111607 (25MHz / 16 / 14, measured value: 111545) and some USB-to-UART converters couldn't work with it at all. With fractional frequency divisor, the measured baud rate becomes 115207, which is quite accurate. Signed-off-by: Rong Zhang Signed-off-by: Thomas Bogendoerfer

MIPS: Loongson64: dts: fix phy-related definition of LS7A GMAC

2026-01-30T14:35:26+00:00

Currently the LS7A GMAC device tree node lacks a proper phy-handle property pointing to the PHY node. In addition, the phy-mode property specifies "rgmii" without any internal delay information, which means the board trace needs to add 2ns delay to the RGMII data lines; but that isn't known to happen on any Loongson board. The ACPI-based initialization codepath, which is used on LoongArch-based 3A5000 + 7A1000 hardwares, specifies "rgmii-id" phy mode, which should be the one we are using. Add the lacking phy-handle property and set proper phy-mode. Tested on a LS3A4000_7A1000_NUC_BOARD_V2.1 board with YT8521S PHY.

MIPS: dts: Always descend vendor subdirectories

2025-12-01T09:06:16+00:00

Commit 41528ba6afe6 ("MIPS: DTS: Only build subdir of current platform") broke building of all DTBs when CONFIG_OF_ALL_DTBS is enabled unless all the various kconfig options were also enabled. The only effect that commit had was getting rid of some harmless build lines such as: AR arch/mips/boot/dts/mti/built-in.a Those lines were part of the built-in DTB support. Since commit 04e4ec98e405 ("MIPS: migrate to generic rule for built-in DTBs"), how the built-in DTBs are handled has changed and those lines are no longer generated, so revert to the prior behavior.
