From 551288bd8ba5db8f7553a9b7e4420fd005767b88 Mon Sep 17 00:00:00 2001 From: John Keeping Date: Thu, 18 Aug 2016 20:08:41 +0100 Subject: [PATCH] rockchip: i2c: move register write out of inner loop There is no point in writing intermediate values to the txdata registers. Also add padding to the debug logging to make it easier to read when there are leading zeroes.
