Subject: [PATCH 09/11] ARM: dts: imx6-sabreauto: add reset-gpios property for max7310_b
Date: Mon, 12 Jun 2017 11:24:02 -0700 [thread overview]
Message-ID: <1497291844-14632-10-git-send-email-steve_longerbeam@mentor.com> (raw)
In-Reply-To: <1497291844-14632-1-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).
