Add Device Trees for Actions Semiconductor S500 SoC and LeMaker Guitar SoM and base board. Signed-off-by: Andreas Färber <afaerber@suse.de> --- v4 -> v5: * Renamed files from s500* to owl-s500* v3 -> v4: * Adopted lower-case timer interrupt-names (Mark) v2 -> v3: * Fixed uart2 reg offset * Enlarged timer reg size * Added 2 Hz timer interrupts, interrupt-names * Disabled CPUs 1-3 for now (cf. later patches) * Added Cortex-A9 SCU, global timer, TWD timer/wdt nodes * Added HOSC clock for timer v1 -> v2: * Reworded subject * Updated ARCH_OWL to ARCH_ACTIONS (Arnd) * Adopted "actions" vendor prefix * Dropped irq.h include * Added memory@0 node for Guitar SoM * Dropped bogus uart3 clock-frequency * Added device_type for CPU nodes * Fixed UART reg size * Adopted SPDX-License-Identifier (Rob) * Added remaining UART nodes * Added timer node arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/owl-s500-guitar-bb-rev-b.dts | 26 ++++ arch/arm/boot/dts/owl-s500-guitar.dtsi | 22 ++++ arch/arm/boot/dts/owl-s500.dtsi | 176 +++++++++++++++++++++++++ 4 files changed, 226 insertions(+) create mode 100644 arch/arm/boot/dts/owl-s500-guitar-bb-rev-b.dts create mode 100644 arch/arm/boot/dts/owl-s500-guitar.dtsi create mode 100644 arch/arm/boot/dts/owl-s500.dtsi
