Subject: [PATCH 0/2] arm64: dts: ti: k3-j72xx-main: Switch MAIN R5F clusters to Split-mode

J721E and J7200 SoCs have two R5F clusters in the MAIN domain, and both
of these are configured for LockStep mode at the moment. Switch both of
these R5F clusters to Split mode by default to maximize the number of
R5F cores. The MCU R5F cluster continues to be in the preferred LockStep
mode.

Note that this configuration is the default for remoteproc mode (kernel
driver boots the R5F processors). These will be overridden for early-
booted remoteprocs through the corresponding IPC-only support in the K3
R5F remoteproc driver.
