Subject: [PATCH v5 4/5] ARM: dts: da850-evm: enable cpufreq
Date: Wed, 17 Apr 2019 17:27:00 +0200 [thread overview]
Message-ID: <20190417152701.23391-5-brgl@bgdev.pl> (raw)
In-Reply-To: <20190417152701.23391-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Enable cpufreq-dt support for da850-evm. The cvdd is supplied by the
tps65070 pmic with configurable output voltage. By default da850-evm
boards support frequencies up to 375MHz so enable this operating
point.
