Subject: [RFC PATCH 01/15] pwm: add the pwm_is_enabled() helper
Date: Wed, 1 Jul 2015 10:21:47 +0200 [thread overview]
Message-ID: <1435738921-25027-2-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1435738921-25027-1-git-send-email-boris.brezillon@free-electrons.com>
Some PWM drivers are testing the PWMF_ENABLED flag. Create an helper
function to hide the logic behind enabled test.
This will allow us to smoothly move from the current approach to an atomic
PWM update approach.

Subject: [RFC PATCH 01/15] pwm: add the pwm_is_enabled() helper
Date: Wed, 1 Jul 2015 10:21:47 +0200 [thread overview]
Message-ID: <1435738921-25027-2-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1435738921-25027-1-git-send-email-boris.brezillon@free-electrons.com>
Some PWM drivers are testing the PWMF_ENABLED flag. Create an helper
function to hide the logic behind enabled test.
This will allow us to smoothly move from the current approach to an atomic
PWM update approach.
