From ec43b08b5733494ad88aa618ecdf534320dd8207 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 20 Nov 2012 22:24:33 +0000 Subject: ssb: add GPIO driver Register a GPIO driver to access the GPIOs provided by the chip. The GPIOs of the SoC should always start at 0 and the other GPIOs could start at a random position. There is just one SoC in a system and when they start at 0 the number is predictable.
