Miller, Greg Kroah-Hartman, Paul E. McKenney, Filip Kokosinski, linux-kernel, devicetree, Joel Stanley This patchset adds a new LiteX SoC-based platform configured for mor1kx (OpenRISC) CPU coupled with LiteUART serial device. Details about LiteX can be found at https://github.com/enjoy-digital/litex. This platform is intended for further extension once drivers for other LiteX devices are merged to the kernel. NOTE: This requires another patchset to be merged first: https://lore.kernel.org/patchwork/cover/1143352/ Filip Kokosinski (1): openrisc: add support for LiteX MAINTAINERS | 1 + arch/openrisc/boot/dts/or1klitex.dts | 49 +++++++++++++++++++++++ arch/openrisc/configs/or1klitex_defconfig | 18 +++++++++ 3 files changed, 68 insertions(+) create mode 100644 arch/openrisc/boot/dts/or1klitex.dts create mode 100644 arch/openrisc/configs/or1klitex_defconfig -- 2.23.0 ^ permalink raw reply [flat|nested] 3+ messages in thread
