Subject: [PATCH 0/5 v7] input: pwm-beeper: add feature to set volume

This series implements volume control for the pwm-beeper via sysfs.

The first patch changes the devicetree documentation from txt to yaml.

The original author of the following patches is Frieder Schrempf.
I picked them from this [0] LKML thread from 2017. Since it looks like
his email address changed in the meantime I changed it in the Author
and Signed-off-by, as well as in the copyright statements.
I did some minor changes on the patches that they apply and work with
the current kernel.

The last patch was added to fix loading/unloading of the driver.

I recently posted a v6 [1], changes since v6:

 * Convert devicetree binding documentation from txt to yaml
 * Use DEVICE_ATTR_[RO|RW] properly
 * Change Frieders Mail address
 * Added Signed-off and Tested-by statements
 * Fix module unloading

Regards
Manuel
