Subject: [PATCH 3/6] ARM: dts: am437x-gp-evm: Add pinctrl for debugss pins
Date: Wed, 7 Nov 2018 10:34:17 +0530 [thread overview]
Message-ID: <1541567060-5671-4-git-send-email-j-keerthy@ti.com> (raw)
In-Reply-To: <1541567060-5671-1-git-send-email-j-keerthy@ti.com>
From: Dave Gerlach <d-gerlach@ti.com>
The pins used by debugss are not configued by default, place pulldowns
on the pins for maximum power savings during sleep.
Signed-off-by: Dave Gerlach <d-gerlach@ti.com>
[t-kristo@ti.com: converted to use AM4372_IOPAD macro]
