Subject: [PATCH 03/13] ARM: tegra: Add gpio-ranges property
Date: Wed, 17 Jun 2015 15:42:13 +0200	[thread overview]
Message-ID: <1434548543-22949-4-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <1434548543-22949-1-git-send-email-tomeu.vizoso@collabora.com>

Specify how the GPIOs map to the pins in Tegra SoCs, so the dependency is
explicit.

This currently will add a duplicated entry in the map from pins to gpios
in the pinmux controller but it should be harmless and will be fixed in a
later commit.

Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>

---

v2:	* Change number of gpios to 251 to match pinctrl-tegra124.c
	* Add note about duplicated mapping
	* Add the property to all the other Tegra SoCs
