Hello All, This series adds the QoS for DSS on J721E, J721S2 and J784S4 family of SoCs.
Before adding the support, cleanup is done for AM62A QoS support[0] and common bit mask defines are moved to the common file so that they are not defined every time we add QoS support for a new K3 platform.
Further, to simplify the logic, macros are used to populate the value of registers and values as suggested by Andrew[1]
Before adding QoS support, we need to map the ORDERID to the traffic type (RT/NRT) in J7 platforms. On J721E, ORDERID 0-7 and 8-15 are two groups which needs to be mapped. We are mapping 0-7 to NRT and 8-15 ORDERID as RT for both NAVSS0_NBSS_NB0 and NAVSS0_NBSS_NB1 On J721S2 and J784S4, we have 3 groups, 0-3, 4-9, 10-15. Here we are mapping first two groups as NRT and 10-15 as RT for both NAVSS0_NBSS_NB0 and NAVSS0_NBSS_NB1.
Changelog v1->v2: - Simplify the logic to populate values[1] - Remove ASEL type which is to be taken up separately as suggested in [2]
