该驱动因为版本问题，代码中的snd_soc_codec方法被弃用，我们尝试修改代码，但是修改依旧有很多函数报错无法编译通过拿来使用。
而后我们在github上找了一份tas5805m的驱动，如下：
这份驱动可以编译通过，我们将TAS5805M通过I2C挂着之后，驱动proble成功，有如下打印：

通过命令查看TAS5805M在RK3566上被成功注册为声卡。如下：
console:/ # cat /proc/asound/cards
0 [rockchiphdmi ]: rockchip_hdmi - rockchip,hdmi
rockchip,hdmi
1 [rockchiptas5805]: rockchip_tas580 - rockchip,tas5805m
rockchip,tas5805m
2 [ROCKCHIPSPDIF ]: ROCKCHIP_SPDIF - ROCKCHIP,SPDIF
ROCKCHIP,SPDIF
但是喇叭并没有声音出来，我们量了TAS5805M的供电都正常。硬件设计如下：
想请问是否有在RK3566-Android11平台上使用的TAS5805M驱动，或者能否仿照老版本tas5805m的驱动帮忙修改一份能在RK3566上使用的TAS5805M的驱动出来。
我们因为对音频驱动不是很熟悉，尝试修改无法解决，能否帮忙支持一下。
