Serge Vasilugin reports: To improve mt7620 built-in wifi performance some changes: 1. Correct BW20/BW40 switching (see comments with mark (1)) 2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531 3. Set bbp66 for all chains. 4. US_CYC_CNT init based on Programming guide, default value was 33 (pci), set chipset bus clock with fallback to cpu clock/3. 5. Don't overwrite default values for mt7620. 6. Correct some typos. 7. Add support for external LNA: a) RF and BBP regs never be corrected for this mode b) eLNA is driven the same way as ePA with mt7620's pin PA but vendor driver explicitly pin PA to gpio mode (for forrect calibration?) so I'm not sure that request for pa_pin in dts-file will be enough First 5 changes (really 2) improve performance for boards w/o eLNA/ePA. Changes 7 add support for eLNA Configuration w/o eLAN/ePA and with eLNA show results tx/rx (from router point of view) for each stream: 35-40/30-35 Mbps for HT20 65-70/60-65 Mbps for HT40 Yes. Max results for 2T2R client is 140-145/135-140 with peaks 160/150, It correspond to mediatek driver results. Boards with ePA untested.
