Subject: [RESEND PATCH 08/10] ARM: davinci: dm644x: switch to using the clocksource driver
Date: Mon, 22 Jul 2019 15:17:46 +0200 [thread overview]
Message-ID: <20190722131748.30319-9-brgl@bgdev.pl> (raw)
In-Reply-To: <20190722131748.30319-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
We now have a proper clocksource driver for davinci. Switch the dm644x
platform to using it.
