Subject: [PATCH v3 2/2] arm64: dts: realtek: Add RTD1319 SoC and Realtek PymParticle EVB
Add Device Trees for Realtek RTD1319 SoC family, RTD1319 SoC and
Realtek PymParticle EVB.
Signed-off-by: James Tai <james.tai@...ltek.com>
---
v2 -> v3:
* Add virtual maintenance interrupt for architecture timer
* Correct the GIC redistributor address range
v1 -> v2:
* Reserve the boot ROM address
* Reserve boot loader address
* Reserve audio/video FW address
* Reserve RPC and ring buffer address
* Reserve TEE address
* Support 1 GiB RAM by default
* Reduce rbus range to 2 MiB
* Apply the syscon for ISO,MISC,CRT,SB2,SCPU_WRAPPER
* Adjust compatible strings order in document
