+Subject: [PATCH 4/5] cpufreq: add driver for Raspbery Pi
+
+Raspberry Pi's firmware offers and interface though which update it's
+performance requirements. It allows us to request for specific runtime
+frequencies, which the firmware might or might not respect, depending on
+the firmware configuration and thermals.
+
+As the maximum and minimum frequencies are configurable in the firmware
+there is no way to know in advance their values. So the Raspberry Pi
+cpufreq driver queries them, builds an opp frequency table to then
+launch cpufreq-dt.
+
+Also, as the firmware interface might be configured as a module, making
+the cpu clock unavailable during init, this implements a full fledged
+driver, as opposed to most drivers registering cpufreq-dt, which only
+make use of an init routine.

+Subject: [PATCH 5/5] clk: raspberrypi: register platform device for
+ raspberrypi-cpufreq
+
+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.
