[PATCH 16/23] ARM: u300: support regulators in the device tree

Linus Walleij linus.walleij at stericsson.com
Mon Apr 22 05:57:48 EDT 2013


From: Linus Walleij <linus.walleij at linaro.org>

Now that we have enabled board power and the AB3100 regulators,
put the regulator data into the device tree and enable it so
we can start to tie regulators to devices. To begin with we're
only supplying the power to the board itself.
