pwm: pwm-tiehrpwm: PWM driver support for EHRPWM (2012-07-26 07:45:20 +0200)
----------------------------------------------------------------
PWM subsystem for Linux 3.6
The new PWM subsystem aims at collecting all implementations of the
legacy PWM API and to eventually replace it completely. The subsystem
has been in development for over half a year now and many drivers have
already been converted. It has been in linux-next for a couple of weeks
and there have been no major issues so I think it is ready for mainline
inclusion.
The biggest disadvantage of the legacy PWM API is that it allows only a
single implementation and therefore prevents multiple PWM drivers to be
built into the same kernel image. The PWM framework solves this issue
by keeping the same public API, but at the same time adding a core to
which PWM providers can register. This has the advantage that nothing
changes for users of the legacy API, while at the same time allowing the
implementation changes that are required to move away from the global
namespace of PWM devices in order to support multiple PWM providers in
the same system.
