Subject: [PATCH v2 0/2] dt-bindings: arm: keystone: ti,sci: add entries for
 boot mboxes

K3 devices use the system controller HW block to run the TIFS firmware,
currently we document the RX and TX channels only however before the
firmware is loaded, a different set of  mailboxes are required to load
firmware to the HW block.

This patch set documents the missing mailboxes in the binding.

- Remove maxItems entry
- Remove RFC tag from patch (added by mistake in v1)
- Document the new mailboxes in mboxes instead of mbox-names
- Provide example with all the mailboxes set
- Update commit title to have "ti,sci"
- Split into two patches
- Link to v1: https://lore.kernel.org/r/20251111-k3_syscon_add_boot_mailboxes-v1-1-529a27f21076@ti.com
