From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mans Rullgard Subject: [PATCH 1/2] devicetree: mxsfb: add reset-active property Date: Tue, 15 Dec 2015 17:24:56 +0000 Message-ID: <1450200297-19243-1-git-send-email-mans@mansr.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Rob Herring , Pawel Moll , Mark Rutland , Ian Campbell , Kumar Gala , devicetree@vger.kernel.org, linux-kernel@vger.kernel.org Cc: marex@denx.de List-Id: devicetree@vger.kernel.org Some boards connect the LCD_RESET pin to a reset input on the display panel. On these boards, this pin must be set to the proper level for the display to function. This adds an optional "reset-active" property to the "display" subnode such that devicetrees can specify the desired polarity of the LCD_RESET pin.
