This is the development kit board for the Librem 5. The current level of support yields a working console and is able to boot userspace from the Network or eMMC. Additional subsystems that are active : - Both USB ports - SD card socket - WiFi usdhc - WWAN modem - GNSS - GPIO keys - LEDs - gyro - magnetometer - touchscreen - pwm - backlight - haptic motor Signed-off-by: Angus Ainslie (Purism) <angus@akkea.ca> --- arch/arm64/boot/dts/freescale/Makefile | 1 + .../dts/freescale/imx8mq-librem5-devkit.dts | 832 ++++++++++++++++++ 2 files changed, 833 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dts
