From ff3cbc2cb606c8f804b611291efe207d07275a18 Mon Sep 17 00:00:00 2001 From: Andrea Merello Date: Wed, 26 Mar 2014 21:02:05 +0100 Subject: [PATCH] rtl8180: introduce functions for setting ANAPARAM 2 and 3 params rtl8180 has one register for analog converters setting ,rtl8185 has two and rtl8187se has three. Setting those registers require more than a simple write, and for one of them a function is already provided. This patch introduces functions for the other two. rtl8187se will use them. rtl8185 doesen't yet, but should Signed-off-by: Andrea Merello Signed-off-by: John W.
