| Subject: [PATCH] arm64: dts: orange-pi-zero-plus2: enable AP6212a WiFi/BT combo |
| |
| Enable AP6212a WiFi/BT combo chip on orange-pi-zero-plus2 board: |
| - WiFi SDIO interface is connected to MMC1 |
| - WiFi REG_ON pin connected to gpio PA9: attach to mmc-pwrseq |
| - WiFi HOST_WAKE pin connected to gpio PL7 |
| - BT is connected to UART1 |
