Subject: tegra: Allow boards to perform early GPIO setup
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=cb7a1cf36a59772670adcd2c90cee40c2ed1bc60;p=u-boot.git

tegra: Allow boards to perform early GPIO setup

The new gpio_early_init() function, which does nothing by default, can
be overridden by boards to configure GPIOs at an early stage.
