here is the list for Linux 5.3:
cpufreq/raspberrypi-cpufreq.c
gpio/gpio-raspberrypi-exp.c
clk/bcm/clk-raspberrypi.c
staging/vc04_services/bcm2835-audio/bcm2835-pcm.c
staging/vc04_services/interface/vchiq_arm/vchiq_arm.c
staging/vc04_services/bcm2835-camera/mmal-vchiq.c
firmware/raspberrypi.c
hwmon/raspberrypi-hwmon.c
soc/bcm/raspberrypi-power.c (*)
(*) There is already a blob-free driver called soc/bcm/bcm2835-power.c,
but it still needs improvements.
Since the ARM cores doesn't have full access, it may not possible to
replace all these drivers. An alternative approach for blob-freeness on
BCM2837 would be an open VC4 firmware [1].

Good luck
