Subject: [PATCH 07/12] ARM: dts: imx6-sabreauto: add reset-gpios property for max7310_b
Date: Wed, 7 Dec 2016 16:57:48 -0800 [thread overview]
Message-ID: <1481158673-15937-8-git-send-email-steve_longerbeam@mentor.com> (raw)
In-Reply-To: <1481158673-15937-1-git-send-email-steve_longerbeam@mentor.com>
The reset pin to the port expander chip (MAX7310) is controlled by a gpio,
so define a reset-gpios property to control it. There are three MAX7310's
on the SabreAuto CPU card (max7310_[abc]), but all use the same pin for
their reset. Since all can't acquire the same pin, assign it to max7310_b,
that chip is needed by more functions (usb and adv7180).
