Subject: [PATCH 3/4] ARM: dts: iwg20d-q7-common: Add LCD support
Date: Wed, 30 Oct 2019 13:43:33 +0000 [thread overview]
Message-ID: <1572443014-17335-4-git-send-email-fabrizio.castro@bp.renesas.com> (raw)
In-Reply-To: <1572443014-17335-1-git-send-email-fabrizio.castro@bp.renesas.com>
The iwg20d comes with a 7" capacitive touch screen, therefore
add support for it.
