From 49d19cc794e73c3383283a5366ff31572d71a795 Mon Sep 17 00:00:00 2001 From: "Mark A. Greer" Date: Tue, 25 Mar 2014 08:54:33 -0700 Subject: [PATCH] NFC: trf7970a: Only write 'ISO Control' when its changing The current code always writes to the 'ISO Control' register when the RF framing is set. That's not necessary since the register's value doesn't always change. Instead, only write to it when its value is actually being changed. Signed-off-by: Mark A.
