Seems like lots of stuff would break. > A few may break indeed. However, there are very few clocks that are actually exported out of the SoC (2 to 4) and they are very rarely used (usually only one to clock an audio codec). The other affected dts are the boards using the flexcom and my opinion is that we should probably get the flexcom stuff back in the dtsi anyway.. So yes, some out of tree board dts may break but they are pretty easy to fix. Also, the DT ABI compatibility is not broken so I don't expect too much breakage overall. -- Alexandre Belloni, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
