[PATCH 3/3] arm64: dts: ti: k3-am62p5-sk: Reserve 576 MiB of global CMA

[Devarsh Thakkar]

From: Brandon Brnich <b-brnich at ti.com>

AM62p has different multimedia components such as Camera, Display, H264
Video Codec which uses CMA for buffer allocations. We require 576MiB for 12
channel decode-to-encode 720x480 at 30FPS use case.
