To configure DM timer in PWM mode the following needs to be set in OMAP_TIMER_CTRL_REG using set_pwm callback: - Set toggle mode on PORTIMERPWM output pin - Set trigger on overflow and match on PORTIMERPWM output pin. - Set auto reload This is a one time configuration and needs to be set before the start of the DM timer. But the current driver tries to set the same configuration for every period/duty cycle update, which is not needed. So move the PWM setup before enabling timer and do not update it in pwm_omap_dmtimer_config().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
