Hi all,
this aims at adding cpufreq support to the Raspberry Pi family of
boards.

The series first factors out 'pllb' from clk-bcm2385 and creates a new
clk driver that operates it over RPi's firmware interface[1]. We are
forced to do so as the firmware 'owns' the pll and we're not allowed to
change through the register interface directly as we might race with the
over-temperature and under-voltage protections provided by the firmware.

Next it creates a minimal cpufreq driver that populates the CPU's opp
table, and registers cpufreq-dt. Which is needed as the firmware
controls the max and min frequencies available.

This was tested on a RPi3b+ and RPI2b, both using multi_v7_defconfig and
arm64's defconfig.
How do we go about merging this? Stefan, will you pick up patch 3, 6 and
7 and submit them for 5.3/5.4? Viresh has already picked up patch 4.
is it possible to let patches 1,2, 3 and 5 go via clk-tree?

I would take care of 6 and 7.

Stefan
are you fine with the series, since Viresh already picked up patch 4?

are you okay with my suggestion above?

Stefan
