From cf0936b06d8e98a157630e99f647e2ff6d29d7ad Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 20 Nov 2012 22:24:30 +0000 Subject: bcma: 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.
