   8 commit 1e31927aa64545ee97a2a41db9984c9931afc50a upstream.

  10 Recently kernelCI reported the board mt7622-rfb1 has a fail test with
  11 kernel: ERROR: did not start booting whose details could be seen at [1].
  12
  13 The cause is that UART0 can't output anything when it's missing a proper
  14 pin setup with current DTS, so the essential driver is always getting
  15 enabled to fix up the issue.
