UHS 1 SD card not detected on nano

Hi,

  1. the WAR to bypass CMD11 in kernel image (Jetson Nano SD card enters back to high speed mode instead of uhs mode after soft reboot)
  2. has “nvidia,vmmc-always-on” in the dt?

These two patches are for both Nano and NX. This should resolve the low speed issue.

As for the “1)UHS1 SD not detected in Nano.” issue, please try different cards and add vmmc-supply to the gpio you are using.
