From 64882709ef07f3eae29c7afc5aa8b84d12733a72 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 15 Nov 2011 11:54:15 +0000 Subject: mdio-gpio: Add reset functionality to mdio-gpio driver(v2). This patch adds phy reset functionality to mdio-gpio driver. Now mdio_gpio_platform_data has new member as function pointer which can be filled at the bsp level for a callback from phy infrastructure. Also the mdio-bitbang driver fills-in the reset function of mii_bus structure. Without this patch the bsp level code has to takecare of the reseting PHY's on the bus, which become bit hacky for every bsp and phy-infrastructure is ignored aswell.
