Subject: [PATCH 3/5] meson: pinctrl-gxbb: add support for TEST_N pin
Date: Wed, 1 Aug 2018 12:00:21 +0200 [thread overview]
Message-ID: <1533117623-27856-4-git-send-email-narmstrong@baylibre.com> (raw)
In-Reply-To: <1533117623-27856-1-git-send-email-narmstrong@baylibre.com>
The Amlogic Meson GXBB SoCs needs a Secure Monitor call to set the TEST_N
direction, add a special bank to support this pin.
Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
