From e39d5ef678045d61812c1401f04fe8edb14d6359 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Mon, 9 Aug 2010 07:58:48 +0200 Subject: powerpc/5xxx: extend mpc8xxx_gpio driver to support mpc512x gpios The GPIO controller of MPC512x is slightly different from 8xxx GPIO controllers. The register interface is the same except the external interrupt control register. The MPC512x GPIO controller differentiates between four interrupt event types and therefore provides two interrupt control registers, GPICR1 and GPICR2. GPIO[0:15] interrupt event types are configured in GPICR1 register, GPIO[16:31] - in GPICR2 register. This patch adds MPC512x speciffic set_type() callback and updates config file and comments. Additionally the gpio chip registration function is changed to use for_each_matching_node() preventing multiple registration if a node claimes compatibility with another gpio controller type.
