I previously added a msm-vibrator driver to the input subsystem, however that's not the correct approach since the direct register writes should occur from within the clk subsystem based on the conversation at https://lore.kernel.org/lkml/20190516085018.2207-1-masneyb@onstation.org/ So this patch series: - Adds support for setting the clock duty cycle to clk-rcg2.c - Removes the msm-vibrator driver and adds a generic clk-vibrator driver in its place. No one is using this driver at the moment so we shouldn't get any complaints. I also included the defconfig and dts changes. Once this whole series is deemed to be ready, it can be merged in pieces through the different subsystems. I included everything here as one patch series so everyone can see the complete picture of what I'm doing. Sorry it took me awhile to get back to correcting this; was working on other tasks on this phone.
