Any chance to actually review this code before you throw it under a
different maintainer's responsibility?

And what's wrong with patches, why a pull request here?

Since the patchset is spanning several subsystems and some file
dependencies were shared between maintainers, Florian was so kind
to funnell all patches through the Broadcom tree, as the following
mail explains:

https://lore.kernel.org/all/0e154ae3-e0ab-4a4e-aa39-999ea1c720ed@broadcom.com/

Let me summarize the patch history here below:

dt-bindings: clock: Add RaspberryPi RP1 clock bindings - 
	Reviewed-by: Krzysztof and Florian [1,2]

clk: rp1: Add support for clocks provided by RP1 - 
	Stephen: [3]

pinctrl: rp1: Implement RaspberryPi RP1 gpio support - 
	Reviewed-by: Linus W. and Stefan W. [4,5]

misc: rp1: RaspberryPi RP1 misc driver -
	Acked-by: Bjorn H. and Greg [6,7]

pinctrl: rp1: Implement RaspberryPi RP1 pinmux/pinconf support -
	Acked-by: Linus W. [8]

Regarding the testing phase, I and some colleagues at SUSE have tested
the patchset from quite some time now.
