[PATCH 0/7] qcom: add clk-vibrator driver

[Brian Masney]

This patch series adds support for the vibrator that's found on the
Nexus 5 phone. 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@xxxxxxxxxxxxx/

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.
