QCN5502 is a 4x4:4 802.11n WiFi SoC that is very similar to QCA956x. This repo contains QCN5502 initvals for various devices.
After obtaining ath_hal.ko from the manufacturer GPL dump or firmware, the initvals can be extracted using python3 extract_qcn5502_initvals.py ath_hal.ko vals.h
Overall, these initvals are very similar to QCA956x initvals found in ath9k except for adding 0x20000 to many addresses and adding 4th-chain related addresses. I don't know why the initvals are slightly different for different devices but it doesn't seem to make a big difference.
vals_ath9k_proposed.h contains initvals that I'm proposing for inclusion in ath9k. I edited certain values to enable the clock doubler, which matches stock firmware behavior and seems necessary for decent performance.
