This series alters the PWM core to allow the registration of controllers
that begin with inversed polarity output. It also modifies the Broadcom
Kona driver to take advantage of this new call.
Arun Ramamurthy (1):
drivers: pwm: bcm-kona: Dont set polarity in probe
Tim Kryger (1):
drivers
Add a new function to register a PWM chip with channels that have their
initial polarity as inversed. This benefits drivers of controllers that
by default operate with inversed polarity by removing the need to modify
the polarity during initialization.

The bootloaders used with Broadcom mobile SoCs are capable of handling
a device tree separately from the zImage so there is no need for this
option to be enabled.
