What is the name of A53 in master list? Is the NAVSS0_LO and NAVSS0_HI denotes the path from MPU A53?

If so, MPU A53 can access peripherals on MCU and WKUP domain, right?

If yes, Does current Linux driver already implemented to manipulate MCU_perherials and WKUP_peripherals directly?

Hi Tony,

CC_ARMSS0 & CC_ARMSS1 stands for Compute cluster ARM subsystem 0 & 1 for A53 cores. I believe that is what you wanted to know.

NAVSS0/1 are for UDMA.

Yes. That is possible. Ex: A53 used MCU domain mcu_cpsw for ethernet.

Keerthy,

Thanks for reply.

But I did not find CC_ARMSS0 /CC_ARMSS1 in any connectivity matrix tables: Table 3-10 to Table 3-16, which master name in those table stand for MPU computer cluster?

Tony,

The NAVSS0 entries correspond to the A53 connectivity. The A53 can access everything in the system including IP on the MCU domain.

Kyle
