From 8c6bda1a89c148f3a28edc09a76dac9bff57d8ee Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Thu, 21 Apr 2005 17:09:08 -0700 Subject: [PATCH] [TG3]: Fix tg3_set_power_state() Fix tg3_set_power_state to drive GPIOs properly based on the TG3_FLAG_EEPROM_WRITE_PROTECT flag. Some delays are also added after D0 and D3 power state changes. Signed-off-by: Michael Chan Signed-off-by: David S.
