Subject: [PATCH v3 2/3] ARM: davinci: dm365: switch to using the clocksource driver
Date: Fri, 10 Jan 2020 18:16:42 +0100	[thread overview]
Message-ID: <20200110171643.18578-3-brgl@bgdev.pl> (raw)
In-Reply-To: <20200110171643.18578-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We now have a proper clocksource driver for davinci. Switch the dm365
platform to using it.
