    mailbox: omap: Add support for TI K3 SoCs · 9c1f2a5d
    Suman Anna authored
    The TI K3 AM65x and J721E family of SoCs have a new Mailbox IP that
    is based on the existing Mailbox IP present in OMAP architecture based
    SoCs. Each instance of the legacy OMAP Mailbox IP is now a single cluster
    within the newer Mailbox IP instance on K3 architecture based SoCs. A
    single K3 Mailbox IP instance has multiple clusters with each cluster
    providing the same functionality as the existing OMAP Mailbox IP.
    
    Reuse the existing OMAP Mailbox driver to extend the support for this
    newer IP present within the Main NavSS block on K3 SoCs. The K3 family
    of SoCs use 64-bit ARMv8 processors for running Linux, so the driver is
    also enhanced to deal with the differences between the 32-bit message
    payloads and the 64-bit pointers used by the client drivers.
