From b7b23ffcf7d8fac66e9976329a75e8f9bbee2419 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 29 Nov 2013 20:18:15 +0100 Subject: [PATCH] ARM: OMAP2+: Remove legacy smsc911x and smc91x GPMC support When connecting an ethernet chip to the GPMC, such as smc91x or smsc911x, a GPIO has to be requested to be used as an IRQ and also the IO memory for a GPMC chip-select. When booting with DT the chip-select allocation is handled in a generic manner in the GPMC driver and the GPIO to IRQ mapping is made by the DT core so this code is not needed anymore now that mach-omap2 related boards are DT-only.
