Hi,

This is a follow-up of the discussion here: https://lore.kernel.org/linux-clk/20210319150355.xzw7ikwdaga2dwhv@gilmour/

This implements a mechanism to raise and lower clock rates based on consumer workloads, with an example of such an implementation for the RaspberryPi4 HDMI controller.

There's a couple of things worth discussing:

• The name is in conflict with clk_request_rate, and even though it feels like the right name to me, we should probably avoid any confusion

• The code so far implements a policy of always going for the lowest rate possible. While we don't have an use-case for something else, this should maybe be made more flexible?

Ping?
