-Subject: [PATCH] clk: raspberrypi: register platform device for
- raspberrypi-cpufreq
-
-Commit e2bb18347c8e5c4187831f3700c380e3c759601a upstream.
-
-As 'clk-raspberrypi' depends on RPi's firmware interface, which might be
-configured as a module, the cpu clock might not be available for the
-cpufreq driver during it's init process. So we register the
-'raspberrypi-cpufreq' platform device after the probe sequence succeeds.
