From e7f2fcf4bf0b0a227f564fcdde46f3bdd326c1b2 Mon Sep 17 00:00:00 2001

Subject: [PATCH] firmware: raspberrypi: register clk device
Commit 91f2cf4a6b2131016b1ae9c9500245f0572112c7 upstream.
Since clk-raspberrypi is tied to the VC4 firmware instead of particular
hardware it's registration should be performed by the firmware driver.
