针对 Everest Semi 的 ES8388 芯片即将停产的情况，我们在 RK3588 Linux 平台上成功替换了对应的替代型号 ES8390，并成功移植了相关驱动。
据悉，ES8390 与 ES8389 属于同一芯片 IC，共用同一套内核驱动，区别在于 ES8390 的封装设计可以 P2P 即将停产的 ES8388，因此如果原硬件设计是 ES8388 的用户，可以使用 ES8390 直接替代。
若是新产品设计，建议后续使用 ES8389 的封装设计，其性价比会更高。
1. 硬件平台 基于 RK3588J HCD810 主板，进行 ES8388 芯片替换验证。
2. 软件环境 软件环境为：统信桌面操作系统 V20。
3. 驱动移植 (1) 内核声卡部分的改动如下：

4. 测试验证
查看声卡列表 cat /proc/asound/cards 可以发现有 ES8389 设备注册，同时内核 log 信息也显示 ES8389 驱动加载成功。
实测：喇叭、耳机、麦克风功能正常，验证通过。
