It also fixes a bug in the pwm core where the enabled state was incorrect on failed calls to enable. Also, a new function was added to the pwm core to add pwm chips with inversed polarity for chips that have a different default polarity than the core. The prevents incorrect polarity being reported. Debug info has been added to help debug configuring duty cycle and period. These changes are required for the Kona PWM driver to work on Cygnus. The same PWM IP is being used. Changes from v7: - Polarity changes take effect immediately instead of being deferred until enable is called. Changes from v6: - Move new debugging info for duty cycle and period in config function into its own commit. - Add kona_pwmc_prepare_for_settings() function to remove duplicated code. Changes from v5: - Address Dmitry's comment on code cleanup of pwm_enable() in pwm core. - Including all patches from different contributors in this patchset. Some were left out in v4. Changes from v4: - Rebased to Tim Kryger's patch that adds support in pwm core to add driver with inversed polarity. - Removed patch 2 that resolved difference between hardware default polarity and pwm framework default polarity. The default polarity is set properly now when the pwm driver is registered with the pwm framework.
