   4 Subject: [PATCH] Revert "firmware: raspberrypi: register clk device"
   5
   6 This reverts commit 91f2cf4a6b2131016b1ae9c9500245f0572112c7.
   7
   8 Revert this because the clock driver won't probe without a DT node, and
   9 creating it as a platform device won't give it one. Doing so avoids the
  10 following error message:
  11
  12     raspberrypi-clk raspberrypi-clk: Missing firmware node
