Subject: ARM: dts: keystone-k2hk: Add MSM RAM node
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b4d15ba8e7d23b9bfd859f414977d081ef0eed68;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: keystone-k2hk: Add MSM RAM node

Add the RAM managed by the Multicore Shared Memory Controller (MSMC)
as a mmio-sram node. The 66AK2H SoCs have 6 MB of such memory. Any
specific MSM memory range needed by a software module ought to be
reserved using an appropriate child node.
