Subject: [PATCH 0/3] TI K3 R5F remoteproc support on J7200 SoCs

Hi All,

The following series enhances the K3 R5F remoteproc driver to add support
for the R5F clusters on the newer TI K3 J7200 SoC family. The J7200 SoCs
have 2 R5FSS clusters, and both clusters are capable of supporting either
the LockStep or Split-modes like on the existing AM65x and J721E SoCs.

The R5FSS IP though is revised compared to K3 AM65x and J721E SoCs and has
two new features: 
 1. TCMs are auto-initialized during module power-up, and the behavior
    is programmable through a SEC_MMR register bit.
 2. The LockStep-mode allows the Core1 TCMs to be combined with the 
    Core0 TCMs effectively doubling the amount of TCMs available.
    The LockStep-mode on previous SoCs could only use the Core0 TCMs.
    This combined TCMs appear contiguous at the respective Core0 TCM
    addresses.

The series is based on 5.10-rc1, and can apply on top of the current rproc-next
branch as well. Following is the patch summary:
 - Patch 1 updates the dt-bindings
 - Patch 2 introduces new SoC data logic and handles the TCM auto-init
   feature
 - Patch 3 handles the TCM adjustment logic in Split-mode

regards
Suman
