TI中文支持网ti的各位大神，你们好。
我们自己做的板子，使用am3352平台，电源管理芯片使用的是tps650250，这个芯片不与I2C连接，我讲4.9.28内核移植到板子上以后发现MMC卡功能不能正常使用，/dev/目录下面没有mmc开头的设备，经过在omap_hsmmc.c驱动的probe中加载打印发现probe函数执行过程中调用omap_hsmmc_reg_get函数时返回失败。
怀疑是自己修改的设备树文件有问题，麻烦各位大神帮忙看下设备树中mmc相关的配置是否哪里有问题，谢谢。

Jian Zhou：
首先和您确认下，U-boot下可以初始化并引导MMC卡么？
LONGFEI LI1：
回复 Jian Zhou:
可以的，这个板子在老的版本（3.2内核）上跑的很好，所有功能都正常。更新到4.9.28内核后需要配合设备树，感觉应该是设备树配置有问题，求帮忙看下我的设备树关于mmc的部分是否有哪里不正确，谢谢。
