2020-06-19clk: bcm: rpi: Discover the firmware clocksMaxime Ripard1-12/+141
The RaspberryPi4 firmware actually exposes more clocks than are currently handled by the driver and we will need to change some of them directly based on the pixel rate for the display related clocks, or the load for the GPU. Since the firmware implements DVFS, this rate change can have a number of side-effects, including adjusting the various PLL voltages or the PLL parents. The firmware also implements thermal throttling, so even some thermal pressure can change those parameters behind Linux back. DVFS is currently implemented on the arm, core, h264, v3d, isp and hevc clocks, so updating any of them using the MMIO driver (and thus behind the firmware's back) can lead to troubles, the arm clock obviously being the most problematic. In order to make Linux play as nice as possible with those constraints, it makes sense to rely on the firmware clocks as much as possible. However, the firmware doesn't seem to provide some equivalents to their MMIO counterparts, so we can't really replace that driver entirely. Fortunately, the firmware has an interface to discover the clocks it exposes. Let's use it to discover, register the clocks in the clocks framework and then expose them through the device tree for consumers to use them.

2020-06-16reset: simple: Add reset callbackMaxime Ripard2-0/+27
The reset-simple code lacks a reset callback that is still pretty easy to implement. The only real thing to consider is the delay needed for a device to be reset, so let's expose that as part of the reset-simple driver data.
