pn557 upgrading OS from Android 13 to Android 15

[Dennis89]

我们一直在开发具有PN553和PN557 NFC功能的Android 15设备。
（系统Android版本为15，之前一直是Android版本为13，这次我们需要为PN557升级）
NFC移植的参考源代码具体从链接网址获取源代码。

问题1：

请告诉我应该参考哪个具体链接获取源代码，期待您给一个地址。

问题2：

源代码同时支持PN553和PN557？
还是，它只支持PN557？

期待您们的回复，谢谢！

Hi  jimmy:

Thank you for your patient replies and explanations! So, can I understand that the PN557 product itself supports upgrading/porting to Android 15, but your official team has not provided a dedicated porting guide for the PN557? I look forward to your reply! Thank you!

PN557 information is not public. I cannot find any driver source code and document for this product. I think you could check this product with local NXP distributor and NXP Marketing to request the support of it.

Unfortunately, there is no Android 15 porting guide for PN557. We only have porting guide for PN7160 and PN7220.
