Subject: [PATCH 4/8] clk: davinci: add a reset lookup table for psc0
Date: Wed, 21 Mar 2018 13:08:03 +0100	[thread overview]
Message-ID: <20180321120807.18032-5-brgl@bgdev.pl> (raw)
In-Reply-To: <20180321120807.18032-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

In order to be able to use the reset framework in legacy boot mode as
well, add the reset lookup table to the psc driver for da850 variant.
