[PATCH v2 0/8] Enable QoS for DSS on J7 family of TI SoCs
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]

QoS bit mapping are common across all K3 SoCs so move those defines to common header file (k3_qos.h). This ensures that we do not define these for each SoC.

For the QOS registers, instead of using the raw values for calculation for each reg field, use a defined macro which takes in argument for all the reg fields to get the desired value. Do the similar simplification for QOS register and group registers and make the corresponding changes for am62a_qos_uboot file.

Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is done by setting the DSS DMA orderID to greater than 7.
Before setting up the QoS, the ORDERID needs to be mapped to VBUSM sources using setup_navss_nb() function call that sets the threadmap for NBSS registers. (Section 10.2.10.1.2 "NB Parameters" in TRM[0])
Section 3.3.2 "Quality of Service (QoS)" in the TRM[0] provide more details.

Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is done by setting the DSS DMA orderID to greater than 9.
Before setting up the QoS, the ORDERID needs to be mapped to VBUSM sources using setup_navss_nb() function call that sets the threadmap for NBSS registers. (Section 10.2.9.2.10 "Quality of Service" in TRM[0])
Section 3.2.1 "Quality of Service (QoS)" in the TRM[0] provide more details.

Enable Quality of Service (QoS) blocks for Display SubSystem (DSS), by servicing the DSS - DDR traffic from the Real-Time (RT) queue. This is done by setting the DSS DMA orderID to greater than 9.
Before setting up the QoS, the ORDERID needs to be mapped to VBUSM sources using setup_navss_nb() function call that sets the threadmap for NBSS registers. (Section 10.2.9.2.10 "Quality of Service" in TRM[0])
Section 3.2.1 "Quality of Service (QoS)" in the TRM[0] provide more details.

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.
[...]
Applied to u-boot/next, thanks!
