#https://lkml.org/lkml/2016/6/14/967

Pwm channels don't send uevents when exported, this change adds the
channels to a pwm class and set their device type to pwm_channel so
uevents are sent.

To do this properly, the device names need to change to uniquely
identify a channel.  This change is from pwmN to pwm-(chip->base):N

When disabling an omap device (not when removing the driver), the
device is removed but the hwmod's linger.

Fix the resource leak and the crash when calling omap_device_idle()
after the device's omap data have been removed.

Having an omap serial device without a serial aliases doesn't
work. For now fallback to using the hwmod instance.

When using DT the driver devm_kalloc's platform data and assigns them
directly to the pdev->dev.platform variable.

This is wrong since device de-registration expects the data to be
kmalloc'ed instead, resulting in a crash.

Fix by copying the platform data to a kmalloc buffer.

We are going to need the overlays to appear on sysfs with runtime
global properties (like master enable) so turn them into kobjects.

They have to be in sysfs so that people can have information about the
overlays applied in the system, i.e. where their targets are and whether
removal is possible. In a future more attributes can be added
in a backwards compatible manner.

A throw once master enable switch to protect against any
further overlay applications if the administrator desires so.

A kernel command line option is provided as well.
