- port configs/cubie_a5e/linux-6.6/board.dts from linux-5.15 (keep hardware config, add radxa,a527 compatible per 5.15->6.6 port convention) - add configs/default/linux-6.6/bsp_defconfig from tina1.5.0 - add missing boot0_nandfastboot_sun55iw3p1.bin
- board.dts: add always-on wifi_power_en (PM2) and wifi_chip_en (PM1) fixed regulators per radxa a733 scheme, drop conflicting power_en/ wlan_regon from rfkill node so sunxi-rf can probe (aic8800 dkms depends on sunxi_wlan_get_bus_index) - bsp_defconfig: enable AW_GMAC/AW_GMAC_METADATA/AW_STMMAC_ETH and friends for ethernet
Bluetooth (hci0) was created but non-functional: HCI Reset timed out (0x1003 tx timeout) because PG6-PG9 (UART1 TX/RX/CTS/RTS) were left UNCLAIMED. Add the uart1 pin group and wire pinctrl-0/pinctrl-1 into &uart1 so the pins are muxed to UART function. PG bank stays at 1.8V; no uart-supply added pending schematic review.
- sdc2 (eMMC): disable by default (base SKU has no eMMC, avoids CMD1 timeout) - twi0: disable (no board-level pinctrl/device, avoids pinctrl probe error) - keep rfkill empty pinctrl props and 1.8V BLDO1 wlan_power: removing them makes mmc1 (wifi SDIO) stall with dma hold bit timeout and RCU hang - bsp_defconfig: enable CONFIG_SND_SOC_SUNXI_CODEC_HDMI for HDMI audio

There was a problem hiding this comment.
这两个不是布尔值呀，应该还有具体的pinctrl引用和字符串名称
Use panfrost (mainline, supports Mali-G57 Valhall) instead of the vendor ARM mali-valhall driver: - gpu: override compatible to arm,mali-valhall-jm so panfrost binds - gpu: name the bus clock "bus" so panfrost enables bus-gpu (fixes the soft reset timeout) - gpu: use lowercase interrupt-names (job/mmu/gpu) as panfrost matches them case-sensitively (fixes IRQ not found) Userspace note: the sunxi display engine cannot scan out panfrost's AFBC framebuffers, so export PAN_MESA_DEBUG=noafbc (e.g. in /etc/environment) until the de_afbd decoder supports the format.
