From 9899b81e7ca5c285b825ff10ca9357dd18813d83 Mon Sep 17 00:00:00 2001 From: Mike Sinkovsky Date: Wed, 4 Apr 2012 19:33:53 +0000 Subject: Ethernet driver for the WIZnet W5300 chip Based on original driver from chip manufacturer, but nearly full rewite.

This mirrors the device tree property nvidia,vbus-gpio. This makes the VBUS GPIO handling identical between booting with board files and device tree; the driver always does it. This removes the need for board files to request and initialize the GPIO early during their boot process, perhaps even before the GPIO driver is ready to process the request.

This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on Emma Mobile EV2. Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on two I/O memory ranges and the 32 GPIOs are hooked up to two interrupts. In the case of Emma Mobile EV2 this GPIO building block is used as main external interrupt controller hooking up 159 GPIOS as 159 interrupts via 5 driver instances and 10 interrupts to the GIC and the Cortex-A9 Dual.
