Subject: [PATCH 10/17] ARM: davinci: da850: switch to using the clocksource driver
Date: Fri, 11 Jan 2019 18:21:27 +0100
Message-ID: <20190111172134.30147-11-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.
