Subject[PATCH v4 3/8] ARM: dts: Prepare Realtek RTD1195 and MeLE X1000
Date
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, updated memreserve & memory]
Signed-off-by: Andreas Färber <afaerber@suse.de>
---
v3 -> v4:
* Inserted /memory reg entry to compensate reduced r-bus size (James)
* Extended GIC reg and added interrupt (Marc)
* Added comments to /memory node

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
