   4 Subject: [PATCH] overlays: Deprecate and delete the sdtweak overlay
   5
   6 The sdtweak overlay has been superseded by the board-specific
   7 sd_* parameters such as sd_poll_once, sd_overclock etc.
   8
   9 For example, replace:
  10
  11     dtoverlay=sdtweak,poll_once
  12
  13 with:
  14
  15     dtparam=sd_poll_once
  16
