+From b2691aee386b18425a7b96cca05e3bcceb8678ae Mon Sep 17 00:00:00 2001

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