Subject: [RESEND PATCH 1/2] devicetree: mxsfb: add reset-active property
Date: Tue, 12 Jan 2016 10:22:20 +0000 [thread overview]
Message-ID: <1452594141-26073-1-git-send-email-mans@mansr.com> (raw)
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.
