Add Device Trees for Realtek RTD1195 SoC and MeLE X1000 TV box. Reuse the existing RTD1295 watchdog compatible for now. Reviewed-by: Rob Herring <robh@kernel.org> [AF: Fixed r-bus size, fixed GIC CPU mask, updated memreserve] Signed-off-by: Andreas Färber <afaerber@suse.de> --- v2 -> v3: * Fixed r-bus size in /soc ranges from 0x1000000 to 0x70000 (James) * Adjusted /memreserve/ to close gap from 0xa800 to 0xc000 for full 0x100000 * Changed arch timer from GIC_CPU_MASK_RAW(0xf) to GIC_CPU_MASK_SIMPLE(2) squashed from RTD1395 v1 series v1 -> v2: * Dropped /memreserve/ and reserved-memory nodes for peripherals and NOR (Rob) * Carved them out from memory reg instead (Rob) * Converted some /memreserve/s to reserved-memory nodes arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/rtd1195-mele-x1000.dts | 31 ++++++++ arch/arm/boot/dts/rtd1195.dtsi | 127 +++++++++++++++++++++++++++++++ 3 files changed, 160 insertions(+) create mode 100644 arch/arm/boot/dts/rtd1195-mele-x1000.dts create mode 100644 arch/arm/boot/dts/rtd1195.dtsi
