Subject: Re: [PATCH v3 04/25] clk: bcm: rpi: Allow the driver to be probed by DT

Quoting Maxime Ripard (2020-05-27 08:45:00)
> The current firmware clock driver for the RaspberryPi can only be probed by
> manually registering an associated platform_device.
> 
> While this works fine for cpufreq where the device gets attached a clkdev
> lookup, it would be tedious to maintain a table of all the devices using
> one of the clocks exposed by the firmware.
> 
> Since the DT on the other hand is the perfect place to store those
> associations, make the firmware clocks driver probe-able through the device
> tree so that we can represent it as a node.
