Subject: [Patch v4 1/6] pwms: pwm-ti*: Get the clock from the PWMSS (parent)
Date: Mon,  7 Mar 2016 14:39:42 -0600	[thread overview]
Message-ID: <1457383187-17166-2-git-send-email-fcooper@ti.com> (raw)
In-Reply-To: <1457383187-17166-1-git-send-email-fcooper@ti.com>

The eCAP and ePWM doesn't have their own separate clocks. They simply
utilize the clock provided directly by the PWMSS. Therefore, they simply
need to grab a reference to their parent's clock.
