Subject: [PATCH v4 05/11] ARM: davinci: da830: switch to using the clocksource driver
Date: Mon, 18 Mar 2019 13:10:54 +0100 [thread overview]
Message-ID: <20190318121100.28132-6-brgl@bgdev.pl> (raw)
In-Reply-To: <20190318121100.28132-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We now have a proper clocksource driver for davinci. Switch the da830
platform to using it.
