Subject: [PATCH 16/17] ARM: davinci: dm646x: switch to using the clocksource driver
Date: Fri, 11 Jan 2019 18:21:33 +0100 [thread overview]
Message-ID: <20190111172134.30147-17-brgl@bgdev.pl> (raw)
In-Reply-To: <20190111172134.30147-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We now have a proper clocksource driver for davinci. Switch the platform
to using it.
