From 53a759c89b7924b2cd218b40fa4b51f9220f20b1 Mon Sep 17 00:00:00 2001 From: Martin Wetterwald Date: Thu, 13 Apr 2017 10:08:44 +0200 Subject: smsc95xx: Add comments to the registers definition This chip is used by a lot of embedded devices and also by the Raspberry Pi 1, 2 & 3 which were created to promote the study of computer sciences. Students wanting to learn kernel / network device driver programming through those devices can only rely on the Linux kernel driver source to make their own. This commit adds a lot of comments to the registers definition to expand the register names.
