Subject: arm64: dts: mediatek: mt8195-demo: update and reorder reserved memory regions
From: Macpaul Lin <macpaul.lin@xxxxxxxxxxxx>
commit 6cd2a30b96a4b2d270bc1ef1611429dc3fa63327 upstream.
The dts file of the MediaTek MT8195 demo board has been updated to include
new reserved memory regions.
These reserved memory regions are:
- SCP
- VPU,
- Sound DMA
- APU.
These regions are defined with the "shared-dma-pool" compatible property.
In addition, the existing reserved memory regions have been reordered by
their addresses to improve readability and maintainability of the DTS
file.
Cc: stable@xxxxxxxxxxxxxxx # 6.1, 6.4, 6.5
