Hello Georgi, This small series adds interconnect driver support for SDX55 platform for scaling the bandwidth requirements over RPMh. The driver has been tested on SDX55-MTP and gives below DDR metrics using mbw [1] tool: Src port: SDX55_MASTER_AMPSS_M0 Dest port: SDX55_SLAVE_EBI_CH0 Command: mbw 100 With bandwidth 500000: AVG Method: MEMCPY Elapsed: 0.59058 MiB: 100.00000 Copy: 169.324 MiB/s With bandwidth 700000: AVG Method: MEMCPY Elapsed: 0.29267 MiB: 100.00000 Copy: 341.678 MiB/s With bandwidth 900000: AVG Method: MEMCPY Elapsed: 0.19608 MiB: 100.00000 Copy: 510.005 MiB/s The copy speed seems to be the same for all bandwidth less than 500000 and greater than 900000. Note: The CPUFreq governer needs to be set to something other than schedutil to see the difference. Otherwise the speed seems to be the same for all bandwidth. Thanks, Mani [1] https://github.com/raas/mbw Changes in v2: * Changed the copyright year to 2021, fixed Kconfig dependency and constified provider struct definitions.
