What about the other problems like wrong settings width, wrong settings position and missing settings? Should I resend them? Btw. keep in mind that the functions have conflicting settings (different PINs). Kind regards, Sven

The pinctrl-rt2880 code doesn't support multiple functions with the same name. This will result in incorrect pinmux configuration. The MT7621 uses 2 bit wide configuration of the sdhci, spi, mdio, pcie, wdt, uart2 and uart3. But the code only changed a single bit for uart3, uart2 and mdio. Also the order of uart2 and uart3 group was exchanged. The spi "nand" settings was also reserved only 7 PINs instead of 8 as the spi "spi" setting.
