ramips: create shared DTSI for MT7620 Phicomm K2x series devices Improve compatibility of the device tree include file. Now a new .dtsi file will support both PSG1218A, PSG1218B and K2G.

ramips: add new flash layout support to Phicomm K2 Descriptions： Phicomm K2 (PSG1218) got a new "permanent_config" partition after update firmware to v22.5. This partition located in front of the firmware partition, same as The Phicomm K2P and K2G. Due to this change the new bootloader can't load previous firmware any more. This commit is aimed at add support for Phicomm K2 which official firmware version is 22.5.x or newer. For which runs old firmware version, just update OpenWrt that has a prefix of "k2-v22.4". For uniform naming, this commit also changed the model name PSG1218 to a more recognizable name K2, refer to Phicomm K2G, K2P K2T. OpenWrt selection table: official firmware version OpenWrt v22.4.x.x or older phicomm_k2-v22.4 v22.5.x.x or newer phicomm_k2-v22.5 Installation: Same as Phicomm K2G, K2P, PSG1208. a. TFTP + U-Boot b. Open telnet by some web page vulnerability (Search Baidu by key words "K2 telnet"), and then we can upload firmware image to /tmp and write it to firmware partition with mtd instruction.

mac80211: rt2x00: experimental improvements for MT7620 wifi 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.
